The funeral for James Davies was held at the Denver First Church of the Nazarene.
"The procession following the funeral will leave the church and proceed westbound on Hampden Ave. to Wadsworth Blvd., then northbound to Alameda Ave., then westbound to Kipling St., then northbound to W. 6th Ave., then westbound to Indiana St. and finally southbound Indiana St. into the Jefferson County Fairgrounds," according to a statement released by Lakewood Police.
Traffic delays are expected along the procession route.
In the 42-year history of the Lakewood Police Department, Davies is the first officer to die in the line of duty.
"We will learn from this, every time an officer is lost in the line of duty, there are lessons learned. Lessons learned from this incident we will pass this along to other agencies in hopes they never have to experience a similar tragedy," Lakewood Police Chief Kevin Paletta told 9NEWS.
He says the department feels the loss every day.
"We're going about our duties with heavy hearts," Paletta said. He says during these difficult times, the the department is encouraged by the outpouring of the community.
Davies was in a backyard investigating reports of gunfire and was in full uniform when another officer behind a fence shot him on Friday.
Police say 37-year-old Joe Anthony Ruiz is accused of firing gun shots that led to the police shooting.
He appeared in court Sunday to be advised of his rights.
Officers were investigating reports of a prowler in the neighborhood when they heard the gunfire.
Police then set up a perimeter around Ruiz's house as they prepared to search the place.
