Tucson police are investigating a deadly motorcycle collision from Saturday night, according to a news release from the department.
TPD says at 11:11 p.m. officers and members from the Tucson Fire Department responded to a report of a serious injury collision involving a motorcycle and a vehicle at East Pima Street and North Sahuara Avenue.
As officers arrived, they located an adult male motorcycle rider with obvious signs of trauma.
Paramedics immediately transported the man to Banner University Medical Center with life-threatening injuries.
Shortly after arrival, the man succumbed to his injuries and was pronounced dead at the hospital.
The motorcycle rider has been identified as 25-year-old Christopher Campbell.
Police say the adult male driver was not injured during the incident.
Detectives from TPD's Traffic Investigations Unit were able to determine that the rider of a black 2004 Triumph motorcycle was eastbound on Pima Street in the median lane approaching North Sahuara Avenue.
Detectives say the driver of a 2006 silver Saturn was westbound on Pima Street and made a southbound turn onto Sahuara Avenue.
The motorcycle struck the Saturn on the passenger side of the vehicle. A helmet was found at the scene but it is unknown if the rider was wearing the helmet.
Police say speed does not appear to be a factor in the collision and there were no signs of impairment from the driver of the Saturn.
No citations have been issued by police at this time.
