Investigators have identified the father of a child left trapped inside his car seat after a highway accident.
California Highway Patrol officers identified 40-year-old Fabiani Arroyo as a person of interest in Sunday night's crash on southbound Interstate 5 near San Diego.
Officers say Arroyo's black Nissan Titan veered off the highway near Rosecrans Street and landed on its side on an embankment.
Arroyo's 4-year-old son was spotted by witnesses as partially ejected from the vehicle. The boy was hanging out of a window but still buckled in his car seat.
According to CHP officials, the driver took off running immediately following the crash, but then returned to the scene to unbuckle the child from the vehicle.
CHP Officer Juan Escobar said the child fell on his back and hit the concrete curb. Officials said the child fell approximately 10 feet.
The driver then got scared and took off running, according to CHP.
The boy was taken to Rady Children's Hospital with injuries from the collision and the fall, officials said Monday.
His mother has requested the hospital not release updates on her son's medical condition.
CHP officers are now looking for Arroyo as a person of interest in the investigation not only because he is believed to have been the driver who fled the scene but also because he may have caused his son additional injuries if he was the man who unbuckled the child after the crash.
Anyone with information regarding Arroyo or the crash can contact the California Highway Patrol at (619) 220-5492.
