The man arrested in the fatal shooting during opposing rallies in Denver has been identified as a private security guard for a local TV station.

KUSA (AKA 9News) revealed that Matthew Dolloff, 30, was the man who was taken into custody by the police on Saturday. Dolloff was contracted through Pinkerton, a private security agency, by the TV station. 

“It has been the practice of 9NEWS for a number of months to contract private security to accompany staff at protests,” the station stated on their website.

Dolloff was initially being held at the Denver Downtown Detention Center for suspicion of first-degree murder after an argument resulted in gunfire. The man who was shot was transported to a nearby hospital where he was later pronounced dead.

On Sunday, police confirmed that Dolloff was indeed the man they arrested and revealed that he was being charged with first-degree murder.

“Matthew Dolloff (DOB 03-07-1990) is being held for Investigation of First Degree Murder in connection w/the shooting that occurred yesterday at 10 W. 14th Ave. This remains an active investigation; any additional updates will be released as it becomes available. #Denver,” the DPD stated in a tweet.

Joe Montoya, division chief of investigations for the Denver Police Department, revealed that police were initially in the area on Saturday to keep “two groups with opposing views” apart.

At the time, a “Patriot Rally” was set for 2 p.m. while a counter-protest “BLM-Antifa Soup Drive” was scheduled for 1:30 p.m. to “drown out” the opposition.
