Colorado DA: 'Active Investigations' into Migrant Gang Activity

Arapahoe County District Attorney John Kellner says the state is aggressively prosecuting gang-related crimes and has a multi-agency task force investigating the problem.

Colorado has "open and active investigations" into gang activity, according to Arapahoe County District Attorney John Kellner.

Kellner, who spoke to Fox News's "America's Newsroom" on Friday, said that law enforcement is aggressively prosecuting any gang-related cases that come across their desks. He also said that there is a multi-agency task force looking into these crimes.

"Whenever we see a gang try to infiltrate our community or get a foothold, we're going to prosecute them vigorously," Kellner said.

Kellner's comments come after Democratic Colorado Gov. Jared Polis called migrant gang violence at Aurora apartment complexes "misinformation."

However, Kellner strongly disagrees with the governor's assessment.

"This isn't 'misinformation,'" Kellner said. "Right now there's an active investigation into a massive shootout that occurred outside one of these apartment complexes, and one man ended up dead. That's not misinformation. These are real problems."

Kellner pointed to previous initiatives combating members of the Mexican gang MS-13 that attempted to plant roots in the city.

"We indicted over a dozen members of that gang, prosecuted them for multiple murders, multiple shootings, violent crimes, and several of them are spending the next few decades looking back on their life choices in prison and regretting them," Kellner said. "And some of them are spending the rest of their lives in prison in Colorado."

The apartment building at the center of the controversy has been overrun by alleged gang members, according to one resident.

"I've heard criticism from some folks saying things like 'This is imaginary,'" Kellner continued. "I can tell you the people in this apartment complex, the people of aura, it's not imaginary.

"This is a real example of how cities across the country that are extremely far away from our border are dealing with the impacts of a failed border policy."

According to reporting from the New York Post, more than 40,000 migrants have arrived in the Denver area since December 2022.

"The situation is real, but it also needs to be put into context so that the reputation of an entire city of over 400,000 residents is not adversely impacted by what has occurred in several isolated apartment buildings owned by the same out-of-state slum lord," Aurora Mayor Mike Coffman said in a previous statement to Fox News Digital.
