Baby 'Left In Car By Forgetful Dad' Found Dead
The man told investigators that he had forgotten to drop his child off with a babysitter, San Jose Police Department spokeswoman Sergeant Heather Randol said.
The man parked his SUV in a residential street and picked up a van he reportedly uses for work.
The baby remained inside the parked SUV for 10 hours until his father returned to find his son unconscious, ABC reported.
He called police shortly after 7pm on Wednesday, but it was too late.
The boy was pronounced dead a short time later, Sgt Randol said.
One local resident who knows the father and was working near the parked car told local news he had no idea the baby was inside because the vehicle has tinted windows and the child was not crying.
Another neighbour, Kevin Carroll, told the San Francisco Chronicle he had walked by the SUV three times but did not notice the baby.
Mr Carroll told the newspaper he saw firefighters go into the SUV in the evening and heard one of them say: "The baby is dead".
It is not clear how hot it was inside the SUV. Temperatures on Wednesday were reported at around mid-20sC (mid-70sF) but they might have been significantly higher inside the vehicle.
The Santa Clara County District Attorney's Office is reviewing the case, but no charges have been filed so far.
The identities of the father and baby have not been disclosed.
