Former paramedic threatened to 'go sniper' on supervisors at Denver Health, affidavit says

DENVER - Court documents outline how far a former Denver paramedic was allegedly willing to go to get even with supervisors, who he blamed, for the loss of his job.

Police arrested 38-year old Matthew Mann on April 11, after threats he allegedly made on Facebook led to a partial lockdown at Denver Health Medical Center.

The affidavit for a search warrant indicates that Mann posted a message that read, “Going sniper on anyone wearing bars” [referring to a Lieutenant’s collar insignia].

Mann worked as a paramedic at Denver Health from 2004 to 2012.

He told police that his superiors blamed him for an ambulance crash and that they believed he was careless and reckless. He said he was facing termination, so he chose to resign.

Just after midnight on April 11, Mann started posting messages online. They were seen by coworkers, the affidavit said.

One received a text message from Mann which said, “I should go in there and kill those (expletive.)”

The co-worker wrote back and asked Mann if he was OK.

Mann replied, “I’m pretty far from okay.  I’ve got (names of supervisors) and many more already scouted, positioned and set.  I’m ready to kill almost everyone with bars and I’m trying to find a reason not to do it.”

According to the affidavit, Mann also texted that after killing his former supervisors he would disappear into the mountains.

“I’ll kill their children if I have the opportunity just to remove their DNA from the gene pool,” Mann texted.

The affidavit shows that once Mann was arrested, he told police that he had a psychotic break and was venting his anger on the message board.

When an investigator asked if he still wished to shoot the command staff, Mann replied, “Honestly, (expletive) yeah. They are a tumor and they need to be excised. They are a disease, a disease controlled by money.”

According to the affidavit, Mann told police he knew where his supervisors lived and even spent time in a field adjacent to one of the homes, with a rifle.

“I’ve spent nights and days outside their homes with them in the cross hairs just waiting,” he said.

The court document states that Mann told investigators he studied each residence to determine what order he should kill them to ensure his escape.

Mann has been charged with four counts of stalking and making threats. He has posted a $50,000 bond.

7NEWS tried to contact Mann to get his response to the affidavit and was told that he’s not commenting.

When asked about details in the court document, Denver Health released a statement that simply said, “The safety of our workforce is important to us.  Denver Health takes any and all threats of violence against our employees seriously.”

Mann told investigators that since his resignation, he’s been working as a gunsmith and opened a gun shop called Mann Precision Arms.

The affidavit states that he is also a certified concealed carry instructor, a certified survivalist and self-taught long-range precision shooter.

“Mann said he could shoot a fifty-cent piece at a distance of 1,000 yards with his custom-made .338 Lapua rifle,” the affidavit states.

During the police interview, Mann said he owns between forty-five and fifty firearms.

He voluntarily consented to let the Denver Police Department take temporary custody of his firearms for safekeeping.

Mann is due back in court May 24.
