MIAMISBURG, Ohio (AP) — One man is dead and three people were detained in a nearby city after a shooting on Interstate 75 in Ohio, authorities said.

Sgt. Paul Neinhaus of the Miami Township police department says occupants of a blue Jeep began shooting at about noon Monday at a car driven by a 64-year-old man in the southbound lanes of I-75.

The Dayton-area man was found deceased in his vehicle, which had been hit three times and was found pulled off the side of the highway, police said.

Lt. Mike Siney told reporters that it’s unclear whether road rage prompted the shooting or whether the victim and his assailant or assailants knew each other.

A suspect vehicle was spotted by a Middletown police officer and stopped, and Siney said the female driver was arrested on several outstanding warrants. Police said she and two other people were being questioned in the shooting, which closed the highway for about three hours.
