The San Diego County Sheriff’s Department (SDSO) released new details Friday on the mysterious case of two women and a teenager found dead inside a Rancho Santa Fe home earlier this week.

The SDSO officially identified the adults as Ihnwon Mia Shin, 56, and Sayeh Amini, 52, and the girl as 15-year-old Hannah Arya.

The sheriff’s department said the San Diego County Medical Examiner’s (ME) office had completed the autopsies on the bodies and confirmed the manner of death for both Shin and Arya was homicide. Both victims suffered multiple sharp force injuries, the SDSO said.

Amini is the suspect in the homicides, officials said. She also died from multiple sharp force injuries but her manner of death was determined to be suicide.

The bodies of the murder-suicide victims were discovered on Monday around 11:50 a.m. inside a sprawling home located in the 17000 block of Via De La Valle in San Diego’s North County.

NBC 7 spoke with Carl Starrett Thursday night, an attorney representing Amini’s family. Starrett told NBC 7 Amini was the sister of Michael Arya, the owner of the Rancho Santa Fe home.

Michael died of cancer this past April and had lived at the property prior to his passing.

Starrett said Michael had appointed Amini to manage his affairs after his death and the responsibility of handling her late brother’s estate became overwhelming for Amini.

“It’s just a horrible situation," Starrett told NBC 7.

The SDSO has not released details on the motive behind the murder-suicide. Check back for updates.

With both parties now having their presumptive nominees and with new battleground-state polling and maneuvering to chew on, NBC News updated its battleground map. The result: Hillary Clinton maintains her advantage, having 255 electoral votes in her column to Donald Trump's 190; 93 are in Tossup. Back in May, it was Clinton 253, Trump 190, Tossup 95. The big changes from two months ago: We moved Florida from Tossup to Lean Dem; Nevada and Pennsylvania from Lean Dem to Tossup; Utah from Likely GOP to Lean GOP; Mississippi and Montana from Lean GOP to Likely GOP; and New Jersey from Lean Dem to Likely Dem.

About a dozen people were on a roller coaster that became stuck on the tracks at Six Flags Over Texas Friday morning.

The New Revolution Virtual Reality Coaster — formerly known as The Shockwave — stopped on the tracks during ride's initial ascent about 11 a.m.

Park officials said a sensor indicated a possible problem with the ride and stopped the train at a "safe place."

While the issue was investigated, crew members brought water to the stranded passengers. After a short wait, passengers were escorted down the emergency ramp at 11:25 a.m.

Sharon Parker, with the theme park, said the ride will be shut down for an inspection. Parker did not say when the park hoped to reopen the ride.

No further details have been released.

On Wednesday, eight people were escorted off a stuck roller coaster at Frontier City in Oklahoma.

The Oklahoma riders, which included children aged 7 to 15, were stranded on the coaster for about an hour before they were safely removed.

A new state law, co-authored by a San Diego legislator, went into effect Friday, requiring parents to vaccinate their children before they can go to school.

Students in all public and private K-12 schools in the state, licensed day cares, preschools and after school programs must get more than 10 federally recommended vaccines, or they will have to be home schooled, according to the law. 

Home schooled students and those in individualized education programs are exempt.

Governor Brown signed the bill last year creating a universal vaccine mandate for all children in the state.

The vaccine debate provoked strong feelings on both sides with some parents feeling it took away their right to figure out what is best for their children, while others didn’t want their own kids getting sick by being exposed to unvaccinated children.

Among the strictest vaccine laws in the country, the law goes too far in the opinion of thousands of parents who feel it makes medical exemptions too difficult to get.

Heather Hawkes decided to move to Florida with her two girls after the California law was passed.

“My older daughter had a pre-existing medical condition,” Hawkes explained. “It was just infuriating to think that we’d been working with a team of specialists and doctors to make a decision for her health and the state was coming in and acting like a medical provider and take that decision from us.”

She said she’s getting a medical exemption in Florida.

Doctor J. Howard of Sharp Rees-Stealy Medical Center told NBC 7 medical reasons to avoid vaccinating children are very rare.

“Other doctors in the community have chosen, since they have an anti-vaccine stance, to accept off-the-wall things like a family history of asthma. We do not feel that’s a valid reason.”

Birdey Elementary parent Shawn Vandriver was alarmed several years ago to find out his son’s school had high rates of parents not vaccinating their children.

He said he respected their choices, but did not want it to endanger his son’s health.

“I would say that parents that choose not to vaccinate their children, they are making a choice. They’re choosing to home school their children,” Vandriver said.

Parents can exempt their children from the law if they feel it goes against their family’s personal beliefs, but they would have already needed to have filled out an exemption form and have gotten it approved by the end of last year.

The bill is open-ended, which means the state could add more required vaccines in the future.

About $25 million was dispensed by federal health officials Friday to help states at risk from Zika defend against its spread — cash taken from other programs because Congress has not approved fresh funding to fight the virus, NBC News reported. 

New Zika funding has been deadlocked in Congress, despite demands from President Barack Obama for increased funding to the tune of $1.9 billion. 

"I expect Congress to get this funding done before they leave for vacation, before they adjourn. That's part of their basic responsibility," Obama said.         

Republicans in the Senate presented a $1.1 billion spending plan with provisions that Democrats said were unacceptable. 

The Centers for Disease Control and Prevention said there are 935 confirmed cases in at least 45 states and Washington D.C. Another 2,000 cases were reported in Puerto Rico, Samoa and the U.S. Virgin Islands.

San Diego’s biggest 4th of July fireworks show, the Big Bay Boom, goes down Monday, and is expected to draw up to a half-million patriotic spectators.

Two senior ISIS commanders were killed in a U.S.-led coalition airstrike in the Iraqi city of Mosul, according to the Pentagon, NBC News reported. 

Basim Muhammad Ahmad Sultan al-Bajari, the terror group's deputy minister of war, and Hatim Talib al-Hamduni, an ISIS military commander, were killed in the June 25 airstrike, the U.S. military said. 

Al-Bajari, a former member of al Qaeda, oversaw the original offensive to capture Mosul in June 2014, the Pentagon said. Hatim Talib al-Hamduni was an ISIS military commander in Mosul and the head of military police for the self-proclaimed Ninawa state. 

The airstrikes come as Iraqi forces claim to have freed the city of Fallujah from ISIS’ grip.

A female giraffe from the San Diego Zoo prematurely delivered a dead calf while being transported to the Calgary Zoo in Canada, Calgary Zoo officials said.

Marci, a five-year-old Masai giraffe, was seen breeding with a male giraffe a couple of months ago, but zoo officials were not sure if she was pregnant or how far along she might be. 

“Although she did not show any signs of pregnancy, San Diego Zoo Global officials advised the animal care staff at the Calgary Zoo of the possibility,” the Calgary Zoo said in a statement.

While it is the policy of both the San Diego Zoo and Calgary Zoo to not move giraffes in their third trimester, it is often difficult to tell how far along a giraffe is in her pregnancy.

The San Diego Zoo believed Marci was likely in her second trimester, which is typically a safe time to travel, according to Jamie Dorgan, Director of Animal Care at the Calgary Zoo.

A necropsy on the stillborn fetus revealed that she was in her third trimester.

"If we had more information, more precise information, and thought she was nearing her pregnancy, we would've held off on the shipment, and I'm quite comfortable the SD Zoo would've as well,” Dorgan said.

Marci was under constant observation during the entire trip through closed circuit cameras, and the team took action as soon as she delivered," according to the Calgary Zoo.

Giraffe populations are rapidly declining due to poaching and habitat loss; Marci was being sent to the Calgary Zoo to help boost the future of the Masai giraffe species.

The San Diego Zoo is not commenting on what happened, simply saying that they did not have a veterinarian during the transport.

Marci is healthy and settling in well in Canada, zoo officials said.

Currently the San Diego Zoo Safari Park has six males and three female Masai giraffes.

The San Diego Zoo has four males and four female giraffes.

Federal health officials on Friday widened an already big recall of flour after four more people got sick from food poisoning linked to the flour, NBC News reports.

No one has died or developed the most dangerous symptoms from the E. coli infections, but 42 people have become ill from the General Mills flour, the Centers for Disease Control and Prevention and the Food and Drug Administration said.

The CDC said health officials have found harmful E. coli 0121 strains in General Mills flour collected from the homes of ill people in Arizona, Colorado, and Oklahoma. On Friday, the CDC said Indiana has been added to the list of states with ill people. 

The General Mills recall covers types of Gold Medal Flour, Gold Medal Wondra Flour, and Signature Kitchens Flour.

A former Ohio seminary student who pleaded guilty to trying to adopt and buy baby girls in Mexico so he could sexually molest them was sentenced in San Diego Friday to more than 15 years behind bars.

In April, Joel Alexander Wright, 23, admitted to seeking sex with infants he wanted to adopt from Tijuana. He will serve 188 months in federal custody, the office of U.S. Attorney Laura E. Duffy, of the Southern District, confirmed.

At Wright's sentencing, U.S. District Judge Dana M. Sabraw also imposed the added condition of lifetime supervision.

In his plea agreement, Wright admitted he had written numerous explicit emails in which he described, in graphic detail, his desire to sexually assault girls under the age of 4 in Mexico.

“There are no words to describe the horror that might have happened, had an innocent baby been placed in this man’s arms,” Duffy said in a statement in April.

Wright, a former seminary student at Pontifical College Josephinum in Columbus, Ohio, had plans of becoming a priest.

At his sentencing, Judge Sabraw noted that in his role as a seminary student, Wright held himself out as someone kind, thoughtful and trustworthy, when all the while he plotted a heinous crime.

"This defendant represents the darkest of demons," Duffy said Friday. "His attempted crime was unthinkable. I applaud our law enforcement partners for stopping Wright in his tracks, and for all their efforts to keep children safe from individuals who have a sexual interest in children both here in the United States and abroad.”

On Nov. 25, 2015, investigators said Wright began posting ads on Craigslist seeking a female tour guide in Mexico, according to his guilty plea.

When an unidentified witness replied to his ads, he told the witness he wanted to “adopt/own a baby girl (under the age of 3)” and have sexual intercourse with her, according to the plea agreement.

According to court documents, Wright also communicated via email with an undercover agent. In an email with the investigator, Wright said he had purchased infant pain relief medication and a “pretty outfit” for a 1- or 2-year-old in anticipation of a would-be encounter with the child.

On Jan. 29, 2016, Wright flew into the San Diego International Airport. There, he called the undercover agent with whom he had been emailing and told him he had landed in San Diego. Wright thought the agent was going to help him get to Mexico and did not realize he had been communicating with someone in law enforcement. 

Wright had two cell phones and a duffel bag. Inside, the bag agents found baby clothes, sleep aids, bottles, toys, candy and lubricant, prosecutors said.

Special agents with Homeland Security Investigations approached Wright outside the airport’s baggage claim area and arrested him on the spot.

According to officials with U.S. Immigration and Customs Enforcement (ICE), Wright had planned to travel from San Diego to Mexico to have sex with at least three babies. He pleaded guilty to one charge of attempted enticement of a minor.

Wright will have to register as a lifetime sex offender.

Hillary Clinton’s campaign is holding a contest to select a supporter who will give a speech on stage at the Democratic National Convention in Philadelphia to formally nominate her as the party’s presidential nominee, NBC News reports. 

Supporters have to submit a video explaining what Clinton’s nomination means to them and why they think she should be the next president. 

Judges are looking for “comfort on camera, charisma” and “a compelling personal narrative,” according to the contest rules. The winner will be flown to Philadelphia to speak at the event and will receive one night in a hotel for an estimated value of $2,500.

The campaign has been holding a number of high-profile contests to inspire small-dollar fundraising, including dinners with Clinton and tickets to see the Broadway hit "Hamilton" with the former secretary of state. 

Democrats are considering approving what is being called the most progressive platform in the party's history, though supporters of Bernie Sanders are still not satisfied with provisions on trade and some other issues.

A draft of the platform, obtained by NBC News, was approved by a 15-member subcommittee and sent Friday to members of the full platform committee. The committee will have a chance to make changes before the platform is voted on at the Democratic National Convention later this month in Philadelphia.

The draft platform states Americans should earn $15 per hour. It calls for abolishing the death penalty. The draft platform also calls for making community college free and easing student loan burdens. It calls for giving the District of Columbia statehood and banning assault weapons.

However, some of the stickiest issues remain unresolved -- at least as Sanders supporters see it.

The sister of slain actress Sharon Tate said she’s doing what she can to make sure convicted Manson Family follower Leslie Van Houten dies behind bars. 

Debra Tate told NBC News she has delivered 138,700 signatures to California Gov. Jerry Brown’s office asking him to deny Van Houten’s parole bid after nearly 50 years in prison. 

"I feel very strongly that she should remain behind bars," Tate said. "It came out at her last parole hearing that she is in communication with Charles Manson."

Van Houten said Manson did write to her, but she turned the mail over to authorities and did not write back. 

Now 66, Van Houten was deemed “suitable for parole” in April by the Board of Parole Hearings. She was convicted along with other cult members of the 1969 killings of Leno and Rosemary LaBianca. She was not part of the crew that killed Tate and four others in a rented home.

San Diego’s beaches are expected to be packed over the Independence Day weekend, and accordingly lifeguards plan to bring in extra staff.

The Fourth of July is typically the busiest beach weekend of the year with tens of thousands of people flocking to the coast.

The ocean should to be warm this weekend, which means a lot of holiday beachgoers will be in the water.

There will be 20 lifeguards in Mission Beach alone over the weekend, and 30 on the Fourth.

Police will also have command posts at popular beaches.

Police and lifeguards are reminding beachgoers to not bring alcohol or glass or tents that close in all directions. Only open tents are allowed.

They also advise owners to leave their pets at home until after 6 p.m.

Plastic containers are allowed, but remember to pack out all trash so the beaches stay clean.

Swimmers should stay in areas where they can touch the ground, always swim with a buddy, and use lifeguard stands as a reference to where they were originally swimming. Beachgoers should always check with a lifeguard before getting in the water.

“You might see a spot where it’s inviting. Rip currents look inviting. They don’t have any waves. It looks like a nice calm area, but it’s just a big, deep hole where the water recirculates,” Lt. Rick Romero of San Diego Lifeguards said.

Lifeguards say kids get lost every year during the Fourth, so parents should keep a close eye on their kids; Police usually see an uptick in pool drowning deaths over the holiday as well, so parents need to watch kids closely when they’re swimming in the backyard.

The surf is expected to be up to five feet.

Presumptive Republican nominee Donald Trump has dedicated a lot of time in his recent speeches and rallies to rehashing past primary contests and attacking fellow Republicans, NBC News reports.

On Friday, Trump spoke at the Western Conservative Summit in Denver about his defeat in Colorado, how Indiana turned out to be his firewall and that he was robbed of delegates in Louisiana. Consistently throughout the week, Trump lauded his historic primary accomplishment, telling crowds that he earned the "most votes in the history of the Republican primary system.”

The Trump team has expended considerable energy over the past few weeks normalizing and building out the bare bones operation for the general election.

But for every sound bite that fits a pivot to the general, Trump adds another that looks back at his past successes and slights those in his party who have yet to fall in line.

Scientists and doctors from UC San Diego and Brazil met at Rady Children’s Hospital in Kearny Mesa Friday to share the latest research on the Zika virus and efforts to develop a possible vaccine.

Clinical work on related diseases in the same family as Zika has scientists hopeful.

“The good news is that we have related vaccines that are much closer to development. In fact there's a vaccine for a virus called Dangie virus that is starting to be used in certain parts of the world, and that's in the same family of viruses as Zika,” Doctor Mark Sawyer, a pediatric infectious disease specialist, said. 

Symptoms of Zika are usually mild and last from two to seven days. They include fever, skin rash, conjunctivitis, muscle and joint pain, malaise and headache. The disease can be dangerous for pregnant women, however.

The mosquito-borne virus can spread through sex and has caused women in several countries to give birth to children with birth defects, including microcephaly and Guillain-Barre syndrome.

The virus has also been detected within the U.S.
