A 9-year-old boy with autism was found dead in a swimming pool at an Inglewood park hours after he was reported missing at the same park, police said.

Zavire Dion Portis was last seen just before 4 p.m. on Sunday, Sept. 8 at Vincent Park, 700 E. Warren Lane in Inglewood, according to the Inglewood Police Department.

Police said the boy’s mother stopped her car briefly at the park to get a drink of water from the fountain. When she returned to the vehicle Zavire had wandered away and could not be found.

The only other witnesses were the boy’s two siblings who were also in the car, but they are also special needs children who couldn’t provide information to investigators.

Police brought in a helicopter and a bloodhound to search the area but were unable to find the child.

The Los Angels County Fire Department confirmed they responded to a report at about 9:50 p.m. of a drowning at the park. It turned out to be Zavire.

Police believe it was an accidental drowning, but they planned a full investigation to rule out the possibility of foul play.
