The Denver Police Department has announced that Matthew Mann, 38, had prompted a "modified lockdown" yesterday at Denver Health Medical Center, where he used to work.
At this writing, the facts of the case remain sketchy. But Mann's Facebook page states that he recently ran his own gun-related business and is currently working in the field of "survival instruction."
Photos, video and details below.
The first word of something untoward happening at Denver Health popped up on the Denver police Twitter feed yesterday morning.
Here's that message:
BREAKING: Denver Police are questioning a former employee from DHMC regarding threats made - related to earlier lockdown
— Denver Police Dept (@DenverPolice) April 11, 2013
The DPD later released the basics. According to the department, officers were contacted by Denver Health staff at around 6:58 a.m. yesterday morning about a former employee, subsequently identified as Mann, who had made what are characterized as "possible threats against staff." In response, DHMC went into modified lockdown. According to 7News, that means the hospital remained open, but no one was allowed in or out of the building without ID. The lockdown was put in place at around 11:30 a.m. and lifted a little past 1 p.m.
In addition, DHMC circulated an internal communication to everyone on its system warning people to be on the lookout for Mann, who was feared to be armed and dangerous. A small photo of Mann was included.
Mann's Facebook page certainly suggests that he knows his way around weaponry. He's listed as having worked at Denver Health from 2000 to 2010 -- but a year prior to his departure from the hospital, he's also said to have run Mann Precision Arms, LLC, whose own Facebook page lists a Centennial address on East Panama Drive. It appears to have gone out of business late last year, as indicated by this message on the page from a potential customer:
O.k., I just drove by the Panama location a few days ago and looked inside and Rick is correct, the shop is completely empty, there is NOTHING there but the old sign on the front of the building. Don't know what happened to them, but their website is also completely gone.
In 2013, Mann's Facebook page indicates that he began working as a "senior instructional designer" for Colorado Survival Instruction, an operation that appears to be in its nascent stages; the page has just 72 likes right now.
The profile photo for Colorado Survival Instruction shows some of the gear presumably deemed necessary:
Meanwhile, on Mann's Facebook page, he demonstrates plenty of enthusiasm for firearms. For instance, the April 7 photo directly below is accompanied by this caption: "Couple a sweet ol honeys. Colt .22 short 24k, mother o pearl grip, side loading derringers. Consecutive serial #'s, original box, one even has buck shot scars......yummy." There are also plenty of pro-gun graphics like this one: It's important to note that Denver police reps have not indicated where Mann was arrested, or if he was armed at the time. Neither has information about the nature of the alleged threats been shared. However, Mann was taken into custody on suspicion of felony stalking and misdemeanor harassment.
