Two people died in the region following single-vehicle crashes over the weekend, one south of Bandon and another east of Scottsburg.

Langlois' David L. Allen, 74, was hurt when his northbound 2005 Jeep Cherokee crossed the Highway 101 center line near milepost 279 at 12:15 p.m. Saturday, sped across the southbound lane and crashed into a large tree, an Oregon State Police press release said. Medics took him to Southern Coos Hospital, where he was pronounced dead.

His passenger, Richard A. Standiford, 45, of Langlois, also was taken to Southern Coos Hospital. A hospital spokeswoman said Standiford was treated and released.

Police aren't sure what caused the Jeep to crash. Emergency responders restricted traffic to one lane for about three hours following the crash. Both Allen and Standiford were wearing seat belts and both airbags inflated, a press release said. Bandon Fire Department, Bay Cities Ambulance and the Oregon Department of Transportation responded.

Several hours later, a Eugene woman died after her motorcycle crashed on a county road in Douglas County.

Diane E. Detuerk, 57, was riding a 2009 BMW motorcycle south on Weatherly Creek Road when she attempted to turn left onto state Highway 38. She lost control of the motorcycle and hit a guardrail, an Oregon State Police press release said.

Detuerk was having trouble breathing and had a large laceration on her face when emergency responders arrived, according to a Douglas County Sheriff's Office press log. She died at the scene.

Detuerk was wearing a helmet and riding equipment. A riding partner traveling a short distance ahead of her was not involved in the accident.

Traffic on Highway 38 was closed about 90 minutes following the 5:30 p.m. crash. Douglas County Sheriff's Office, Coos County Medical Examiner's Office, Scottsburg Fire Department, Lower Umpqua Hospital Ambulance, and Oregon Department of Transportation helped at the motorcycle crash site.

OSP troopers from Coos Bay are investigating both crashes.
