(West Chester)--A crushing end to the search for an autistic West Chester boy. The body of 6 year old Joshua Al-Lateef was found in a retention pond near his Wyndtree Drive apartment. Hundreds of volunteers and first responders decended on the West Chester area Thursday, looking for the non verbal child, who went missing around 5:30pm Wednesday. First responders from across the region and state used sonar, drones, K-9's and helicopters in the effort to find Joshua. Volunteers who helped with the search gathered at the Mulhauser Barn Friday for a candlelight vigil.
