A St. Joseph man died Monday after being thrown from his motorcycle over the weekend.

Traffic Officer Scott Gary with the St. Joseph Police Department said 36-year-old Tony Cox was southbound on St. Joseph Avenue around 3 a.m. Saturday on his motorcycle. Gary said a witness reported seeing Cox racing another motorcycle down the Avenue.

“Cox starting getting up onto the southbound 229 exit ramp and failed to navigate the curve,” Gary said. “He went off the right side of the road and hit two drainage culverts.”

Cox was thrown about 15 to 20 feet from his motorcycle and landed in another drainage culvert.

Gary said Cox was wearing a helmet but it was not DOT approved but more of a novelty helmet.

Cox was taken to Mosaic Life Care for treatment then later transported to KU Medical Center. Gary said his family made the decision to take him off of life support late Monday morning.
