Boy dies after becoming trapped in hot car in Sylmar

SYLMAR, LOS ANGELES (KABC) -- A 3-year-old boy died Wednesday after he became trapped in a hot car in Sylmar, police said.

Emergency crews responded to the 14400 block of Foothill Boulevard and retrieved the child from the car around 3:30 p.m. He was transported to Olive View Medical Center, where he was pronounced dead.

Police say the boy was in a yard and then climbed into an unlocked car. Details on how long the child was in the hot car alone were not immediately available.

Police say his father woke up from a nap and found the boy unresponsive.

"At the very least, this is obviously a very tragic accident and it highlights the importance again of not taking for granted where your kids are and what they might be doing," Los Angeles police Lt. Paul Vernon said.

LAPD Mission Station detectives are investigating the incident as an undetermined death. No arrests have been made.
