A 57-year-old Bend man was killed Tuesday when he lost control of his motorcycle on U.S. Highway 395 near Ukiah, and the bike went down an embankment, according to Oregon State Police.

A preliminary investigation indicated that Mark Hall Pfenning was riding a 2009 Buell north on Highway 395 near state Highway 244 when he lost control on a curve to the left. The motorcycle slid on its side across the turnout on the shoulder, according to an OSP news release, and traveled down the embankment.

The time of the crash has not been confirmed. However, a motorist stopped on the side of Highway 395 about 12:50 p.m. when he saw a motorcycle over the edge of the road, the news release stated.

Emergency responders found Pfenning lying near the motorcycle. He was dead at the scene, according to OSP. The state police, who released Pfenning’s identity this morning, are continuing to investigate, the news release stated.
