Armed Man Kills Self at Colorado Amusement Park, Preventing Potential Mass Attack

20-year-old Diego Barajas Medina found dead with explosive devices and guns at Glenwood Caverns Adventure Park in potential mass attack, prompting a sweeping investigation.

Diego Barajas Medina, a 20-year-old man, was found dead at Glenwood Caverns Adventure Park with multiple firearms and explosives, prompting an investigation into a potential mass shooting plot.
Authorities believe Medina, who was wearing a black ballistic vest and helmet, broke into the amusement park Friday night and killed himself there early Saturday.
Medina's brother David claimed that Medina had a fascination with law enforcement and owned guns and a vest because he aspired to become an officer.
Garfield County Sheriff Lou Vallario said Medina could have caused significant damage at the adventure park had he chosen to use his weapons.
Investigators found a message near Medina's body reading, 'I am not a killer, I just wanted to get into the caves', though it's not confirmed if Medina wrote it.
Medina's weapons were identified as untraceable 'ghost guns', highlighting an issue with unserialized, home-assembled firearms.
