The Grant County sheriff's office reports Collin D. Murdock was the passenger in a ATV being driven Friday on private property about seven miles east of Soap Lake. The vehicle hit a skid and Murdock apparently jumped off and hit his head on irrigation equipment.
KPQ Radio reports Murdock's friends drove him to Columbia Basin Hospital in Ephrata where he died Friday evening.
The driver of the ATV, 24-year-old Matthew J. Giandalia of Kent, suffered minor injuries. He was treated and released from Columbia Basin Hospital. Neither Giandalia nor Murdock was wearing a helmet.
