Hill made an initial appearance in King County District Court. He is being held on $150,000 bail and has a second court appearance scheduled for Friday.
According to a probable cause statement released during Thursday's hearing, Hill's girlfriend told police she was assaulted numerous times for more than five hours on Tuesday.
The woman told police she was struck 15 to 20 times by Hill, including being hit with a bottle of alcohol in the legs and torso.
The woman told police she was restrained from leaving his residence for most of the day, and had her cellphone taken by Hill.
The statement also says Hill used a knife to cut up two of the woman's purses and a pair of shoes.
Hill is being held on investigation of third-degree assault-domestic violence and unlawful imprisonment-domestic violence. Both are felonies in Washington state.
