DENVER >> A Colorado sheriff’s deputy was shot and killed today, the third officer to be gunned down in the line of duty in the state in the past five weeks.

El Paso County Deputy Micah Flick, 34, was killed while investigating a stolen vehicle in Colorado Springs, about 70 miles south of Denver, authorities said.

Two other deputies, a Colorado Springs police officer and a bystander were injured, authorities said. All were hospitalized, but the extent of their injuries wasn’t immediately released.

The lone suspect was also killed, authorities said.

The names of the injured officers, the bystander and the suspect were not immediately released.

Sheriff Bill Elder said Flick, who was killed on his 11th anniversary with the department, is survived by his wife and two children.

Colorado Gov. John Hickenlooper said the deadly violence against officers is having a grave impact on the state.

“We will once more come together to provide sympathy and strength for the deputy’s loved ones and pray for the recovery of those injured,” he said in a written statement. “However, we also must come together and say enough is enough. We want each officer, every deputy, to know we are grateful for their service.”

Adams County Deputy Heath Gumm was killed Jan. 24 and Douglas County sheriff’s Deputy Zackari Parrish was killed on New Year’s Day.

Gumm, 31, was shot while chasing a suspect. Parrish, 29, was shot in suburban Denver by a man with a history of mental health issues.

Monday’s shooting occurred in a neighborhood of single-family homes, apartments and retail stores just east of downtown Colorado Springs, a city of about 465,000.

Television coverage showed dozens of emergency vehicles responding to the scene.
