A man arrested for allegedly shooting and killing a man inside of his Green Valley Ranch home early Sunday morning initially told investigators the victim had broken into his home, according to police records.

Michael Lewis, 46, is currently being held for investigation of first-degree murder and possession of a weapon by a previous offender for the incident, which took place in his home in the 4700 block of North Ireland Court.

Denver officers found the victim inside the home with multiple gunshot wounds. An autopsy showed the man had two gunshot wounds to each leg. He was also shot in the back of the head.

He was pronounced dead at the hospital, and has not been identified.

According to the police report, Lewis called 911 and said someone broke into his house and he had to shoot him. He told the dispatcher that he had shot the victim in the leg.

Investigators say there was no evidence anyone broke into Lewis’ home.

Police say Lewis has an extensive arrest record, including felony forgery – a conviction for which he spent five years in prison.

The victim also has an extensive criminal record, and had been arrested for burglary, according to the police report.

The incident remains under investigation.
