A Santa Rosa man arrested following a nearly five-hour standoff with authorities was identified Friday as Michael Albini, 48.

Albini is one of several people who live at a Bucks Road house just south of Santa Rosa where authorities converged Thursday evening after reports of a man firing a gun.

A caller who phoned 911 at about 5:43 p.m. said heard two gunshots coming from his roommate's bedroom. The roommate was reported to be Albini, sheriff's Lt. Clint Shubel said.

Albini and some or all of the five other men at the home had been drinking, which made it difficult to sort out exactly what was happening inside, Shubel said.

Members of the Sonoma County sheriff's hostage negotiations teams contacted Albini as members of the SWAT team took up positions around the single-family home. When the occupants didn't come out of the home as instructed, deputies responded as though they were facing a possible hostage situation, Shubel said.

In later interviews with detectives, however, none of the five occupants removed from the home said they had been held hostage by Albini, he said.

Negotiations continued with Albini for several hours.

"Initially, he was very hostile, breaking stuff inside the house," Shubel said.

As negotiations went on, it appeared Albini was becoming increasingly intoxicated, so SWAT officials opted not to immediately confront him, Shubel said.

The strategy worked, because shortly after 11 p.m., by the time the sheriff's bomb squad maneuvered a remote controlled robot into the house, Albini was lying near a bed, passed out. Detectives located a handgun at the scene, Shubel said.

Albini was taken by ambulance to a local hospital. He was later booked into Sonoma County Jail on suspicion of illegal discharge of a firearm, making terrorist threats, assault with a deadly weapon, being a person prohibited from carrying a firearm and resisting arrest.

He was being held without bail, with his first court appearance scheduled for July 30.
