St. Joseph County Police are investigating an accident that left a man in a wheelchair with severe head injuries Friday evening.
Police say 49-year-old Charles Dawson of Niles was driving his motorized wheelchair down the northbound lanes of State Road 933 in northern St. Joe County when a pickup truck ran into him.
The driver was identified as 37-year-old Joel Hernandez-Villalobos of South Bend. He was not inured but was arrested for operating a motor vehicle without a license.
Authorities do not believe drugs or alcohol were a factor in the crash. They are interviewing witnesses to try to understand why Dawson was operating his scooter in the middle of S.R. 933.
