MIAMI (AP)- A Florida Highway Patrol trooper is dead after authorities say his patrol car was rear-ended by another vehicle while stopped along the shoulder of Florida's Turnpike.

The Florida Highway Patrol says 35-year-old Patrick Ambroise was killed while on duty Saturday evening.

Ambroise was parked on the right shoulder of the northbound lanes of Florida's Turnpike in western Miami-Dade County when investigators say a second vehicle veered onto the shoulder and struck the patrol car.

Ambroise was trapped in his vehicle and pronounced dead at the scene.

The driver of the second vehicle, 19-year-old Jonathan Robert Garcia, was transported by helicopter to Jackson Memorial Hospital with serious but stable injuries.

Ambroise leaves behind a wife and two young daughters.
