OAK HARBOR, Ohio — The Ohio Highway Patrol has identified the third teenager killed Thursday morning in a two-vehicle crash in Salem Township.

Joshua Coy, 19, of Oak Harbor died shortly after the 11 a.m. crash at Magruder Hospital in Port Clinton. Officials initially withheld Mr. Coy’s name because his family had not yet been notified.

Driver Cora Roob, 19, of Port Clinton was pronounced dead at the scene in rural Ottawa County about three miles from Oak Harbor, according to the the Sandusky post of the Ohio Highway Patrol. Her other passenger, Barbara Redfern, 18, of Oak Harbor, died a short time later at the hospital.

A single marijuana joint was discovered in the vehicle, but police are waiting for the results of the autopsy to determine whether drugs contributed to the crash, said Lt. Brian Gockstetter, commander of the highway patrol’s Fremont post.

“It smelled like burned marijuana in the car, so someone had just smoked it prior to the crash,” Lieutenant Gockstetter said. “At this point, [we’re] not sure who.”

Ms. Roob was northbound on Muddy Creek North Road, troopers said, when she stopped at a stop sign at Oak Harbor Southwest Road, then pulled out into the path of an eastbound pickup truck driven by Kenneth Recker, 47, of Port Clinton. Mr. Recker was uninjured.

Ms. Redfern is the niece of Chris Redfern, a former state representative and former chairman of the Ohio Democratic Party.

Oak Harbor Southeast was closed for about three hours after the crash. Lieutenant Gockstetter said he expects the patrol’s investigation to continue for several more days.
