Dozens of police cars and emergency vehicles were involved in a flashing light procession last night as they helped escort the body of the slain Boulder police officer away from the scene of the grocery store massacre.  

Boulder Police officer Eric Talley, 51, was among the 10 people shot dead at King Soopers in Boulder on Monday afternoon when a gunman opened fire. 

In the hours after the massacre, the slain officer's colleagues honored the father-of-seven with a procession as they followed the ambulance carrying his body to a funeral home.   

Footage shot by a helicopter news crew captured the flashing lights of emergency vehicles as they snaked their way across the city at dusk. 

The procession left from the King Soopers grocery store at around 7.45pm.

Along the way, officers and first responders saluted the fallen officer. 

Officer Mark Bliley, head of the Boulder Police Department's union, said Talley was a close friend who was passionate about policing. 

Bliley said that when on the job, Talley had a unique ability to connect with people.

'He was just a highly respected, well-loved person and officer. Just a solid person… I don't know of anyone who didn't like Eric. 

Boulder Police Chief Maris Herold said Talley had been with the Boulder Police Department since 2010.
