Gunman found dead at Glenwood Caverns adventure park, Colorado, wearing full body armor and armed with an assault rifle

A heavily armed man killed himself rather than carry out an apparent plan to shoot up a mountaintop amusement park in Colorado, authorities said on Monday.

Diego Barajas Medina, 20, was found dead in a women's bathroom by a maintenance crew at Glenwood Caverns Adventure Park on Saturday morning, before it opened to the public.

He apparently entered the park while it was closed, armed with an AR-style rifle, a semi-automatic handgun and explosives.

Barajas Medina was wearing body armor and tactical clothing, similar to what a police SWAT team member might wear, authorities said.
