Security company to surrender city license in wake of unlicensed guard's fatal shooting of Trump supporter at Denver rally

Following a settlement agreement with the city on Thursday, Isborn Security Services must surrender its Denver license by Friday.


The security company that employed the unlicensed guard—who is accused of fatally shooting a Trump supporter during dueling rallies in October in Denver—will surrender its own license that permits it to operate within the city limits.

Following a settlement agreement with the city on Thursday, Isborn Security Services must surrender its Denver license by Friday and will not be able to apply for a new license for five years.

Company representatives were scheduled to appear at an administrative hearing on Tuesday about the Oct. 10 shooting, The Denver Post reported.

Isborn Security had contracted 30-year-old Matthew Dolloff. NBC affiliate 9NEWS Denver contracted with the Pinkerton security company to protect the news crew covering the protests, which then subcontracted the job to Isborn Security.

Leftist militants arrived to counter-protest the "Patriot Prayer" rally with a competing event dubbed the "Black Lives Matter-Antifa Soup Drive," but the confrontation quickly turned violent as activists faced off.

On that fateful day, Dolloff reportedly shot 49-year-old conservative demonstrator Lee Keltner dead after a dispute. Dolloff is now facing second-degree murder charges for the alleged killing. He was released Nov. 3 from the downtown Denver jail after posting $500,000 bond.

It was later revealed that Dolloff is an outspoken long-time leftist. "Ran into a Trump supporter with a Trump Button on their shirt. Told them i like their im a racist button. They had nothing to say. #f—trump," Dolloff wrote on Facebook in 2016. Other social media posts uncovered further anti-police views.

A bizarre investigative piece published by 9NEWS exposed the news outlet for contracting four other unlicensed security agents in addition to the far-left gunman since June of this year.

9NEWS admitted that "those guards were not required to go through the extensive training Denver mandates all private security guards receive."

A license requires 16 hours of required training in addition to eight annual hours for renewal. To achieve armed status approved by the Denver Police Department, an applicant must be endorsed by written request.

Denver is one of few Colorado towns that require security companies and security guards to obtain licenses to work in the city. However, there is no statewide regulation of the industry.

A press response embedded in follow-up 9NEWS articles claimed that the publication "does not contract directly with individual security personnel."

"9NEWS contracted with Pinkerton and had directed that security guards accompanying our personnel not be armed. None of 9NEWS’ crew accompanied by Mr. Dolloff on Saturday were aware that he was armed," the public statement read.
