Authorities say a 28-year-old Tulsa woman was killed after crashing her motorcycle in northern Oklahoma on Memorial Day.
The Oklahoma Highway Patrol says the wreck happened Monday afternoon on a county road near Avant, about 25 miles north of Tulsa. According to a preliminary report, Kristen O'Donnell was killed after crashing into a culvert.
A preliminary report says O'Donnell was pinned beneath the motorcycle for an unknown amount of time before a passer-by stopped to pull the vehicle off her. O'Donnell was pronounced dead at the scene.
The highway patrol says the cause of the crash remains under investigation.
