A pair of armed robbers and two others, including the driver of a hijacked UPS truck, were killed in an exchange of gunfire with South Florida police officers after the suspects on Thursday led authorities on a high-speed chase.

The robbers held up a jewelry store before commandeering the UPS truck and holding its driver hostage, according to Coral Gables Police. After fleeing the scene and evading police for dozens of miles, the truck stopped in the middle of rush hour traffic as dozens of armed officers surrounded it.

In addition to the suspects and the driver, a female bystander was also killed in the crossfire. No further details regarding her death and identity have been provided.

"There was exchanged fire between law enforcement and the suspects and unfortunately the suspects are now deceased," George Piro, the special agent in charge of the F.B.I.'s Miami office, said. "But two additional innocent civilians were also deceased."

A total of 19 officers fired at the truck, according to NBC Miami. In one video, a bystander caught between the UPS truck and law enforcement captured video of the shootout from inside their vehicle.

The UPS employee taken hostage was killed in the ensuing shootout. His name was not publicly released, but family members confirmed his death to local news outlets.

"We are deeply saddened to learn a UPS service provider was a victim of this senseless act of violence," the package delivery company said in a statement. "We extend our condolences to the family and friends of our employee and the other innocent victims involved in the incident. We appreciate law enforcement's service and will cooperate with the authorities as they continue the investigation."

The incident quickly sparked criticism of law enforcement's handling of the situation.

Former Department of Housing and Urban Development official Brandon Friedman described the shootout as "appalling." He saidthe department should be held accountable for "choosing to assault the vehicle in the middle of stopped rush hour traffic" and using occupied vehicles as "human shields."

The Coral Gables Police Department declined to comment and the F.B.I. has not responded to NPR's inquiries.
