Investigators say there are no ties between recent shootings involving public officials and a Colorado shooting that killed a man outside the home of a sheriff's deputy and a prosecutor.

Grand County coroner's officials say Joshua Lee Stevens of Coral, Mich., died of multiple gunshot wounds.

The Colorado Bureau of Investigation says it appears that late Monday, Stevens pounded on the door at the home of Deputy District Attorney Heather Stein and sheriff's Lt. John Stein, who live in a former hotel building in Hot Sulphur Springs. Shots were fired after Stevens tried to force his way in. No other specifics on the shooting have been released.

Investigators said Thursday the Steins didn't know Stevens, who had been in town for about a week looking for work. Authorities are trying to determine whether alcohol or drugs affected Stevens' behavior.

Hot Sulphur Springs is near Rocky Mountain National Park.
