Why? The attacking housemate wanted beer money, according to an arrest warrant affidavit obtained by TheDenverChannel.com.

Corey Allen Bush, 38, was arrested July 28 and has been formally charged with three felonies -- kidnapping, menacing with a weapon and assaulting an at-risk adult with a deadly weapon, said Denver district attorney spokeswoman Lynn Kimbrough.

The older man lived on the top floor of a house at East 34th and Lawrence streets, while Bush lived on a lower floor, the affidavit said.

The victim's ordeal began on the night of July 25 when he said Bush came upstairs to his room, demanding "money for beer," the affidavit said.

When the older man said he had no money, Bush began punching him in the head and kicking him in a beating that lasted an hour, the affidavit said.

Bush, who kept pacing back and forth, later "secured" the victim to a chair and used padlocks to lock up the house and turned off the exterior lights, the affidavit said.

Bush then returned with a roofing torch and poured flammable lacquer thinner over the man's head, the affidavit said.

"The suspect then lighted the torch and began waving the flame at him … and told him that he was going to set him on fire," the affidavit said.

Bush, however, turned off the torch and picked up a large knife, the affidavit said.

"The suspect then began slapping the victim with the fixed-blade knife and telling him ... he was going to cut him up and feed him to his dog," the affidavit said.

Bush then continued to beat and kick the man, knocking him to the floor and jumping on top of him, the affidavit said.

"The suspect then began to electrocute the victim about the head and neck with a handheld Taser (stun gun)," the affidavit said.

The torture ended when a third housemate arrived outside the home and heard the victim screaming and crying, the affidavit said.

The third housemate jumped a fence and ran upstairs and found Bush standing over the victim, the affidavit said.

Bush grabbed the knife and the other housemate wrestled it away from him, the affidavit said. Bush fled and the housemate called police.

Police later searched the home and recovered a propane torch and a padlock, the affidavit said.

Bush, who remained in jail Wednesday, was also arrested June 22 at the home and convicted of making threats and disturbing the peace in a separate case, according to court records. He was sentenced to one day in jail.

It's unclear who Bush threatened in the June incident.

Bush was also arrested in 2005 during what was described as a "family violence" incident at another Denver residence, court records show.

He was found guilty of disturbing the peace and an assault charge was dismissed, according to court records. He was sentenced to 70 days in jail.
