The Tucson Police Department has identified the man who was shot and killed on Tuesday night to be 35-year-old Thomas Allen Dickinson.

Officers responded to the homicide near Kolb and I-10 yesterday around 6:45 p.m Tuesday.

According to a media release from TPD:

"Homicide detectives responded to continue the investigation. They were able to determine that the security guard was on duty, but not affiliated or working for the businesses in that area. The guard was traveling in his marked security vehicle from one job site to another. While stopped at the red light at E. Science Park Drive, he reported that an unknown male threw a rock at his vehicle. The guard turned east on to Science Park Drive in an attempt to confront the subject about the incident. The guard lost sight of the male and then relocated him in the desert area northeast of the intersection and an altercation ensued. During the altercation, the male subject reportedly picked up a large rock and the guard fired a handgun at the subject, striking him one time."

Tucson Police say Dickinson was shot by a security guard and was pronounced dead by Tucson firefighters on scene.

The security guard has been detained.
