A black 2005 Chevrolet Avalanche pickup truck was headed east on Blanchard Avenue at unknown speed when it went left of center, striking a parked Jeep Cherokee, which then struck a parked Honda Accord that belonged to Blanchard Avenue residents, according to a Moraine Police Division report.
The impact forced the pickup to drive off the right side of the roadway and strike a pole, coming to rest on the passenger side.
The right front passenger, identified as 58-year-old Damon A. Draper of Dayton, had to be extricated from the pickup. He was taken by CareFlight to Miami Valley Hospital.
The driver, an unidentified man, also was taken to Miami Valley Hospital with suspected serious injuries.
Alcohol impairment was a suspected factor, according to the crash report.
The crash remains under investigation.
