A five-year-old boy died in this Dallas wreck.

Authorities now plan to charge a 17-year-old with negligent homicide in connection with an accident in Dallas that killed a child.

Gabriel Valdez, 5, died in the crash at 10:30 p.m. Tuesday on I-20 near Polk Street.

Police say the teenager was driving an SUV with his mother and three children as passengers when he sideswiped a semi-truck.

Gabriel was riding in the back seat and was ejected from the SUV by the impact of the crash.

He was pronounced dead at the hospital.

It was one of two fatal crashes last night.

Hickory Creek Police and the Denton County Sheriff's department are investigating a fatal wreck on Interstate 35E at the Lewisville Lake bridge.
