“He was dressed in black colored tactical clothing bearing patches and emblems that gave the appearance of being associated with law enforcement,” read the sheriff’s office statement.

“The suspect had been heavily armed with a semi-automatic rifle and semi-automatic handgun with multiple, loaded magazines for both weapons," the statement continued. “He was wearing body armor and what appeared to be a ballistic helmet.”

The bomb squad members also swept the park to find any IEDs that may have been planted on the premises and the rides, said authorities. “Our investigation has so far indicated that nobody in the public was at risk,” continued the sheriff’s office statement. “It would appear that the suspect’s actions were limited to the property of the Glenwood Caverns.”

“While this investigation is still ongoing and very active,” said the sheriff’s office, “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 on our community and first responders.”

“This very sad and tragic incident reminds us how much our Glenwood Springs community means to us,” Nancy Heard, the theme park’s general manager, said in a statement shared with PEOPLE. “We appreciate the swift action and thorough work of the Garfield County Sheriff’s Department and Coroner’s Office, as well as the Garfield County All Hazard Response Team and other authorities assisting in the investigation, working together to ensure the park is safe to reopen. Thank you for all you do.”

The park also noted its safety measures in the statement.

“Multiple security programs are in place including an extensive network of security cameras, alarms, fencing, gates and posted signage,” the park’s statement noted. “Lock-out protocols provide protection for engineering, ride operation and ride-restricted areas, as well as sensitive buildings. The incident on October 28 did not take place in any of these areas and was not related to any rides or attractions.”
