Suspect arrested after deadly shooting in north Denver Wednesday night

Being held for investigation of 1st-degree murder

DENVER - A suspect has been arrested after the deadly shooting in north Denver Wednesday night, the Denver Police Department announced Thursday morning.

Police have not released the suspect's name.

Sources tell CALL7 Investigator John Ferrugia the suspect is Daryl Dwayne Thompson, 42. Thompson was booked into the Downtown Detention Center early Thursday on investigation of first-degree murder, intimidating a witness or victim, tampering with a witness or victim and accessory to a crime, according to jail records. He is being held without bond.

The victim and the suspect were involved in an argument when the suspect pulled a gun and shot the victim at about 8:40 p.m. Wednesday at East 38th Avenue and Grape Street, Denver Police spokesman John White said.

The victim was transported to an area hospital where he later died.

SWAT officers surrounded a north Denver home where the shooting suspect was believed to be barricaded Thursday morning. After a standoff, police said the suspect was not inside, but was arrested several hours later.

The exact cause of death of the victim and his identification will be released by the Denver Office of the Medical Examiner.

Thompson has a lengthy Colorado arrest history dating to 1989, when he was arrested at age 19 for auto theft. He also has 11 arrests for assault, along with arrests for attempted murder, aggravated robbery, domestic violence, violating a protection order, weapons violation, burglary and obstructing police.

Thompson's nicknames are "Mad Dog," "OG Madd" and "Mad Dog O," according to his Colorado Bureau of Investigation arrest history.
