MOUNT MORRIS, Ill. (AP) — The Ogle County Sheriff's Department says two men have died after their motorcycles collided on a highway.

The Rockford Register Star reports a woman riding on one of the motorcycles was also seriously injured in the crash Sunday in northern Illinois. She was taken by helicopter to a Rockford medical center.

The department says a man driving east on Illinois 64 collided with the westbound motorcycle with the female passenger. It's unclear what caused the accident.

Neither the sheriff's department nor the Ogle County coroner identified the victims.
