Investigators are searching for the man who fled after dropping off two critically-injured children at a La Mesa fire station Monday.
In the meantime, there are still questions about why the children’s mother risked their lives to help protect that friend.
A one-year-old girl has died and her 2-year-old brother was still hospitalized Monday night after both were found unconscious in a swimming pool.
Initially, deputies were looking for clues at the Lamplighter Village mobile home park in Spring Valley.
That was not where the two children were injured though. Investigators say the victim's mother lied to protect a friend.
The toddlers' mother was staying at a friend's home on Sunset Avenue near the base of Mount Helix. At around 9:45 a.m., she awakened and realized she couldn't find her children.
The two toddlers were then found unresponsive in a back yard pool officials said.
Instead of calling 911, the mother and a friend put the children in a pickup truck and decided to drive to a nearby hospital.
She and her friend drove the children to La Mesa Fire Station 13 approximately 15 minutes away. Paramedics treated the children and transported them and the mother to Grossmont Hospital.
Investigators are stilling looking for the pickup driver who disappeared from the firehouse on foot.
The children's mother later told investigators she lied to protect her friend from getting in trouble for failing to enclose the pool. That may not be the whole truth either.
Investigators arrested one man and confiscated thousands of dollars in unprocessed marijuana and all the equipment used in the sophisticated growing operation from the Sunset Avenue home.
The home is a rental and worth over a million dollars however investigators described it more like a greenhouse inside.
Neighbor Carmen Young walks her dog Spike daily and said she has always been suspicious of the house.
“It's really, really closed up all the time. The bushes are too high. It's not kept up like the rest of the homes here,” Young said.
At last check San Diego sheriff's investigators say the two-year-old boy survived the trip to Rady Children's Hospital but his condition is unknown.
