MIAMI (AP) — Four people, including a UPS driver, were killed Thursday after robbers stole the driver’s truck and led police on a chase that ended in gunfire at a busy Florida intersection during rush hour, the FBI said.

Both robbers were shot and killed, and the fourth victim was in a nearby vehicle when shots rang out at a crowded intersection in Miramar, about 20 miles north of where the incident began, FBI Special Agent in Charge George Piro said during a news conference Thursday night.

It all began shortly after 4 p.m., when police in Coral Gables received a silent alarm at the Regent Jewelers store in the city’s Miracle Mile area. Coral Gables Police Chief Ed Hudak said during a news conference that two suspects were at the store and that shots were being fired when police arrived.

The suspects fled in a truck, then carjacked the UPS delivery truck and its driver not long afterward to start the chase into the southern portion of Broward County, running red lights and narrowly avoiding some crashes along the way. The UPS truck finally stopped in one of the middle lanes of a busy roadway, caught behind a wall of other vehicles waiting for a red light to turn green.
