Law enforcement officers on motorcycles and in cruisers escorted the body of the fallen officer to Compass Christian Church during a procession ahead of a family and public viewing.
Farrar, 50, was killed last month during a high-speed chase in the Phoenix area that left another officer critically injured.
The 18-year veteran of the Chandler Police Department was struck and killed by 25-year-old Jonathan Altland Jr. at a Gilbert Ford dealership.
A $ 3 million bond has since been set for Altland, who had been driving a stolen vehicle and was also hospitalized following a shootout with several officers.
Gilbert Police Officer Rico Aranda suffered a serious head injury in the incident, according to The Associated Press.
A funeral service for Farrar began Saturday at 9 a.m. local time and was streamed live on the department’s Facebook page.
Chandler Police Chief Sean Duggan praised his colleague’s “passion for service” and called him “the consummate team player.”
“Chris lived a life of service and genuinely cared for others,” Duggan told attendees. “… Officer Chris Farrar is gone from us today, but he will never be forgotten.”
The Arizona Republic said Farrar will receive full police honors posthumously.
