FORWARD TWP — An Arkansas man was killed in a single-vehicle crash early this morning when his pickup truck traveled off Route 68 and ended over a culvert in a small stream in southern Butler County, authorities said.

Michael C. Cain Jr., 25, of El Dorado died at the scene of the accident that happened about 4:30 a.m. Sunday. State police are investigating but it was not immediately known what caused the wreck.

Police said Cain was traveling west on Route 68 in the township when his 2014 Dodge Ram 1500 crossed the center line and left the south side of the road. The truck hit and went over a guardrail, landing on a hillside.

The pickup slid over a concrete culvert and came to rest at an angle — with the passenger side up — in the stream, authorities said.

A neighbor heard the crash and drove to the scene, eventually finding the wreckage, said Butler County Chief Deputy Coroner John Hanovick.

The truck was 150 to 200 feet off the road and could not be seen by passing motorists.

“If (the neighbor) had not heard it,” Hanovick said, “the wreck wouldn't have been found right away. It was pretty far down the ravine.”
