Two people died Thursday morning in separate one-car crashes.

The first crash was reported about 4:23 a.m. on Route 202 in Greene, near Key Hill Road, where police found a 2004 Jeep Grand Cherokee had left the road and hit some trees, killing the driver, according to the Androscoggin County Sheriff’s Office.

Craig Ward, 41, of Winthrop was alone in the vehicle and was pronounced dead at the scene. He apparently crossed the center line and the opposite lane of traffic.

No other vehicles were involved, and no one else was injured.

Ward was not wearing a seat belt. Police do not suspect speed or alcohol were factors in the crash, although the investigation continues.

That area of Route 202 has a speed limit of 50 mph. Chief Deputy Bill Gagne said that section was repaved recently, and the Department of Transportation added rumble strips to the center line, a safety measure meant to alert drivers when they veer too close to oncoming traffic.

The second crash was reported just before 7:30 a.m. on Whichers Mill Road in Alfred. Maine State Police said April Robinson, 52, of Alfred was killed when her car left the road and hit a tree. She was the only occupant of the vehicle.

The cause of the crash is still under investigation.
