Authorities are investigating the social media posts and cellphone records of a 20-year-old man who was found dead with an arsenal of weapons and explosives at Glenwood Caverns Adventure Park in Colorado. The man, identified as Diego Barajas Medina, was discovered over the weekend and is believed to have shot himself after trespassing into the park. Garfield County Sheriff Lou Vallario stated that the man was "well intended to do something very heinous," but the reasons behind his collection of weapons and explosives remain a mystery. Some of the explosives were fake while others, including pipe bombs, were real and capable of causing great harm. The FBI and other agencies are assisting with the investigation. Medina, who did not have a criminal record, lived with his mother and brother in Carbondale. Family and friends claim there were no warning signs or motives for his actions. Investigators have been speaking with the family to learn more about a possible motive. It is unclear if the note found at the scene, stating "I am not a killer. I just wanted to get into the caves," is connected to Medina. The investigation is ongoing.
