OPHIR, Ore. - A bicyclist suffered severe head trauma when he crashed while being towed behind a motorcycle Monday afternoon, the Coos County Sheriff's Office said.
Investigators believe both men were under the influence of drugs, the sheriff's office said.
The motorcyclist has a suspended driver's license - and does not have a motorcycle endorsement, the sheriff's office said.
Medics transported Jesse Dale Kruse, 27, of Gold Beach to Curry General Hospital. He was later flown by helicopter to a hospital in Portland, the sheriff said.
Deputies placed the motorcyclist - 48-year-old George Daniel Hobbs - under arrest on charges of Assault in the Third Degree, Reckless Driving and Reckless Endangering.
He also "currently has Conditional Discharge out of Curry County for Possession of Methamphetamine," the sheriff's office said.
The investigation started just before 4 p.m. Monday with a report of a crash on Nesika Road.
Medics took Kruse from the scene to the hospital as deputies began to investigate.
"Initial evidence from the crash scene alleges Hobbs was 'towing' Kruse with his motorcycle before the crash," the sheriff's office said.
That evidence included witness accounts, as well as surveillance video from a nearby home.
"Using footage from the surveillance cameras and inputting the approximate time of the crash, investigators were able to determine that Hobbs appears to be riding a motorcycle and towing Kruse on a bicycle with a short rope southbound on Nesika Road," the sheriff's office said.
The investigation found that the two were traveling at 20 to 30 mph.
"Both subjects tested positive for the presence of a controlled substance," the sheriff's office added, "leading investigators to believe controlled substances may be a contributing factor to this incident."
