A man was found dead in a bathroom at a popular Colorado amusement park surrounded by explosives, guns, and ammunition, police said Monday.

Authorities are investigating whether 20-year-old Diego Medina committed suicide instead of launching an attack at Glenwood Caverns Adventure Park "of devastating proportions."

Medina is believed to have broken into the park while it was closed, where police say he was armed with an AR-style rifle, a handgun, and explosives. Explosive devices were also found in his vehicle, and he was wearing black tactical gear displaying "patches and emblems that gave the appearance of being associated with law enforcement," body armor, and "what appeared to be a ballistic helmet," the sheriff's office said.

"While this investigation is still ongoing and very active, it is important to realize that given the amount of weaponry, ammunition, and explosive devices found, the suspect could have implemented an attack of devastating proportions upon our community and first responders," the Garfield County Sheriff’s Office said in a statement.

Maintenance workers found Medina's body in a woman's bathroom Saturday morning while getting ready to open the park, Garfield County Sheriff Lou Vallario said.

The message, "I am not a killer, I just wanted to get into the caves," was written on a wall of the bathroom where Medina was found, Villario added, though he could not say whether Medina had written it.

The park was likely to be crowded on a fall weekend during hunting season when people were keen to view the leaves changing colors, the sheriff said. He also noted that because of the extreme elevation of the park, which often requires a gondola to reach, emergency operations in getting anyone wounded to a hospital would have been extremely difficult.

"We had the potential for something heinous and gruesome to happen in this community, and we were fortunate that it did not occur, but it certainly, for lack of a better term, took away the innocence of our community,” Vallario added, per the Denver Post.

Some explosives surrounding Medina and in his vehicle proved to be fake, but others were real. No additional explosives were found in the park, and the guns around Medina had no serial numbers, authorities said, adding that during its preliminary investigation, no criminal record for Medina was found.

Glenwood Caverns Adventure Park is "America’s only mountaintop theme park," its site reads, with it lying "7,100 feet above sea level" on top of Glenwood Springs.
