A driver who lost control of his pickup truck and landed in a retention pond dialed 911 for help before he drowned.

The Florida Highway Patrol on Wednesday was investigating how 22-year-old Umberto Delgado Jr. ended up in the retention pond located off a highway exit ramp in the Orlando suburb of Ocoee.

During Tuesday night's phone call, Delgado was able to tell the dispatcher his location, what happened to him and said he was worried his truck would sink. He told the dispatcher that he was trying to get out before the call ended.

Delgado was pronounced dead by Orlando Fire Department divers who found him in his submerged pickup truck.
