Brighton police officers wear a black ribbon over their badge and fight back tears as the hearse carrying Deputy Heath Gumm arrived at the Adams County Coroner's office.
Gumm was taken to an area hospital and pronounced dead there. The Colorado Fraternal Order of Police law enforcement union named him as Heath Gumm, 32, KUSA reported. The suspect reportedly ran off again, before being caught and taken into custody.
The only suspect description available for the pair is that they are light-skinned, black males or dark-skinned, Hispanic males. He had been with the Adam's County Sheriff's Office since 2013.More news: EU Sanctions Venezuela as Almagro Condemns Presidential Elections
