Law enforcement in Northern Colorado is standing in solidarity with the Arvada Police Department (APD) after the death of one of their officers.

According to a Facebook post from APD, the incident occurred on Sunday (Sept. 11) morning, when police responded to a family disturbance on Arvada's W 51st Avenue.

Upon arrival, police encountered multiple people arguing. A male suspect then opened fire, injuring a female victim and killing 27-year-old Officer Dillon Michael Vakoff, who had been with APD for three years.

"Dillon is an example of everything good you would want in a police officer," said APD. "This is a tragic loss to this community, to this department, but most significantly to his family and loved ones. His service and sacrifice will never be forgotten."

After hearing the news, Northern Colorado police departments began offering condolences to APD:

We are incredibly saddened to learn of the loss of Arvada Police Officer Dillon Michael Vakoff. Please keep Officer Vakoff's family and his APD family in your prayers.
