The suspect was caught later, but two others are at large, authorities said.
Gumm had been with the sheriff’s office since 2012, officials said in a tweet Thursday afternoon. The Colorado Police Officers Foundation has set up a PayPal account to collect donations to help the officer’s family. Donations are also being accepted through the Adams County Sheriff’s Foundation.
“On behalf of the entire sheriff’s office, we are praying for the wife and family of our fallen deputy. Please continue to keep them in your thoughts and prayers, as this is a very difficult time for the sheriff’s office,” Deputy Amanda Overton, a spokeswoman for the sheriff’s office, told reporters at a news conference Wednesday night.
Authorities have said little else about the incident or about possible charges against the suspect. But according to records obtained by The Denver Post, Dreion Martise Dearing, 22, was taken into custody Wednesday night and faces three first-degree murder charges and a felony burglary charge.
The shooting comes a few weeks after another Colorado sheriff’s deputy was killed in a Denver suburb less than 30 miles away.
Zackari Parrish, a 29-year-old deputy, was killed Dec. 31 in what Douglas County Sheriff Tony Spurlock called “an ambush-type attack on our officers.” Residents in an apartment complex in Highlands Ranch, Colo., were awakened by a barrage of gunfire early that morning. Three other deputies and a police officer from another department were wounded.
The suspect was Matthew Riehl, 37, a military veteran and former lawyer with a history of mental illness who had posted videos online criticizing the sheriff.
Authorities said deputies were called to Riehl’s apartment twice that morning, first at 3 a.m., when Riehl called to complain about his domestic partner. He streamed his brief interaction with the deputies on Periscope and can be heard saying he had been “assaulted” — even as he acknowledged that there was no physical contact. Riehl grew angrier and said “they lied” as he appeared to turn his back to the officers.
Riehl’s roommate called officers again shortly after 5 a.m. Authorities said Riehl’s roommate had left the apartment and gave the officers a key to get in. Riehl then barricaded himself inside a bedroom as he fired dozens of rounds from a rifle.
Parrish was shot multiple times, while the other deputies crawled to safety. Riehl was killed during an exchange of gunfire with a SWAT team. Before he was killed, he shot two civilians and another officer with a different police department, authorities said.
The latest shooting in Colorado drew condolences from different agencies and police departments in the state.
