VANDALIA, Ohio (AP) — A police pursuit in Ohio eventually led to the kidnapping of a tractor-trailer driver, spurring another pursuit and a lengthy standoff that culminated in a shootout between two suspects and Ohio state troopers, leaving both suspects mortally wounded.

The initial pursuit began around 1 a.m. Wednesday in London, when a police officer stopped a van. London Police Chief Glenn Nicol said a man and a woman in the van gave the officer false information, then drove away as the officer walked back to his cruiser.

The van ultimately stopped at a truck stop on US 42. The two van occupants got out and were briefly chased on foot by police, including an officer who tried to stop the pair with a stun gun. The male suspect also pointed a gun at the officers but did not fire it, authorities said.

The man and woman then got into a tractor-trailer cab that was unlocked and did not have a trailer attached. The truck driver was in the vehicle at the time, and the truck was soon driven away from the truck stop, hitting a London police cruiser but causing no injuries.

The Ohio State Highway Patrol and officers from other law enforcement agencies then chased the truck cab through several counties before the pursuit ended in Vandalia on Interstate 70 west, near the Dayton International Airport Access Road.

Authorities then negotiated for about four hours with the two suspects before deciding to approach the vehicle in a bid to free the hostage. One of the suspects then fired several shots from a handgun at troopers who returned fire, critically wounding both suspects. No troopers were injured, authorities said.

The truck driver who was taken hostage suffered only minor injuries and was treated at a hospital.

The names of the two suspects were not released.

The Ohio Bureau of Criminal Investigation will lead an investigation into the shooting.
