A man killed by Douglas County SWAT officers Sunday outside a Parker motel was identified today as Ronald Talmage.

SWAT officers shot Talmage, 45, after he threatened them with a gun, according to the Jefferson County Sheriff's Office, which wanted to question Talmage about the slaying of 41-year-old Robert Alurac.

Alurac, from Anchorage, Alaska, was found dead July 23 outside of a home for sale near Morrison while a real-estate agent showed the house to a client.

No arrests have been made in connection to Alurac's death.

The Jefferson County Sheriff's Office said Monday that Alurac's girlfriend, Colleen Kay Barrett, 46, has been missing since about the time of his death and investigators are concerned for her welfare.
