KINGMAN - Motorcycle accidents claimed the lives of two Kingman residents in separate weekend incidents.
A 13-year-old Kingman boy was killed Sunday in an off-road collision with his older brother.
According to Kingman Police Capt. Rusty Cooper, Joshua Graffius was riding in a desert area near Calumet Avenue and North Sage Street with his brother and friends.
Graffius' older brother, 15, jumped his motorcycle off of a berm and landed on his younger brother, who rode into his path at about 2:20 p.m.
A Kingman Fire Department spokesman said both brothers were traveling at a high rate of speed prior to the accident.
Graffius was transported to Kingman Regional Medical Center, where he later died. His brother was also transported to KRMC with a broken leg.
Cooper said no criminal charges would be filed and that both brothers were wearing protective gear.
"The cause of the collision is a tragic accident," he said in an email.
On Friday, the driver of a 1996 Chevrolet Caprice failed to stop at a stop sign at Monroe Street and Louise Avenue, striking Sky Christian Duey, 20, who was killed.
The 77-year-old woman could face charges, but alcohol was not a factor, according to Cooper.
Duey was riding west on a Yamaha off-road motorcycle when the woman struck him.
According to a spokesman with the Kingman Fire Department, Duey sustained serious injuries throughout his body, especially his head.
He was transported to KRMC, where he later died. Duey was not wearing a helmet.
