A 20-year-old man named Diego Barajas Medina was found dead in a woman's bathroom at Glenwood Caverns Adventure Park in Colorado after shooting himself in what authorities are calling a mass shooting prevented by a mass shooter. 

The 20 year old was allegedly wearing tactical clothing that resembled that of SWAT officers and was carrying an AR-style semi-automatic rifle, a semi-automatic handgun, and multiple loaded magazines for each weapon. Authorities also found multiple "improvised explosive devices" in Medina's car.  

According to authorities, Medina snuck into the park before it opened and was planning to commit a mass-shooting event when he apparently had a change of heart, allegedly writing “I am not a killer, I just want to get into the caves,” on the bathroom wall where he was found dead. 

You know what they say, about "a good guy with a gun" right? Well, in this case, Medina was both.
