Police say a man was so severely beaten following an argument over drugs outside an Aurora motel that his injuries "could result in permanent brain injury or possibly death."

Just before 9:00pm last night, police were called to a bloody scene outside of a motel on 44th and Greenlake Way N.

Officers found a man on the ground with a "golf-ball sized bump" on his head and a "significant amount of blood coming from his mouth," laying next to a silver-multi tool and a pair of shoes, a police report says.

"I heard the sound of him gargling his own blood," Officer Adam Beatty wrote in his report. "I feared he might suffocate and gently rolled him onto his side."

A woman at the scene told police the victim had been in a fight with another man, who had run across Aurora, jumped over the median, and fled southbound

Police reviewed security tapes from the motel and identified a suspect, who they discovered was staying at another motel down the street.

Officers arrested the man in his room, where he told police that prior to the fight, he was with another woman and the victim, and they were trying to buy some heroin.

The victim didn't have enough money, which sparked an argument.

The suspect told police the victim pulled out a knife, and that he punched the victim to defend himself.

Police booked the man into the King County Jail for assault. Jail records indicate he has been arrested numerous times for drug possession.

During the arrest, police also found a "very poorly counterfeited $100 bill" in the suspect's wallet, which was taken into evidence.

Thanks to Silver for the tip.
