Two Lawrence men were injured and treated at Lawrence Memorial Hospital after separate one-vehicle accidents Saturday in Douglas County.

Sgt. Steve Lewis, a Douglas County Sheriff’s Office spokesman, said Caleb Bates, 26, rural Lawrence, was injured around 4 a.m. Saturday on a gravel road east of the town of Lone Star when he fell asleep and his 1996 Jeep Cherokee struck a concrete bridge.

Lewis said Bates had left the vehicle at the scene because officers found him hours later at his home. He was taken to LMH from his residence and was treated for his injuries and later released, according to an LMH spokeswoman.

Officers do not suspect alcohol was a factor in the wreck, but Bates was cited for leaving the scene of an accident, Lewis said.

In a separate accident, 17-year-old Shane Humason of Lawrence was injured Saturday afternoon when he lost control of his pickup truck southwest of Lawrence. Lewis said at 2 p.m. Humason lost control on a curve on a gravel road in the 1200 block of East 1135 Road.

Humason, who was wearing his seat belt, had to be extricated from the truck. He was taken to LMH with head and leg injuries but was later released, a hospital spokeswoman said.

Lewis said Monday no citations had been issued to Humason.
