Rahsaun Bush was sleeping in the bed of a York City woman when Kanyleron McDavid -- the woman's ex-boyfriend -- stormed in and attacked him.
Bush responded by pulling out his .40-caliber handgun from under his pillow and firing five times at the man, according to his defense attorney, chief public defender Bruce Blocher.
Bush then fled the woman's home, York City Police have said.
McDavid, 29, of New Bern, N.C., died inside the woman's 417 Walnut St. home of multiple gunshot wounds, according to the York County Coroner's Office.
"The question is whether or not excessive force was used (by my client)," Blocher said.
On Thursday, Bush, 21, of no fixed address, pleaded guilty to voluntary manslaughter and possessing a firearm with an obliterated serial number.
Self-defense? Blocher said Bush acted in what's called "imperfect self-defense," meaning he mistakenly believed he was acting in self-defense.
As part of a negotiated plea agreement, charges of first- and third-degree murder were dropped, Blocher said.
It will be up to presiding Common Pleas Judge Michael E. Bortner to determine the appropriate punishment for Bush, the attorney said.
The judge ordered a pre-sentence investigation to help him make that determination, court records state. Sentencing is set for June 24 for the manslaughter case as well as for an unrelated burglary Bush also pleaded guilty to on Thursday.
The maximum possible sentence for voluntary manslaughter is 10 to 20 years in prison.
Just met: Blocher said his client had only met the woman the day of the homicide. Although Bush was sleeping in bed with the woman, nothing romantic was going on, the attorney said.
Police said McDavid had been in a relationship with the woman for several months, but that it ended the day before he was killed.
McDavid had returned to her home to retrieve his cellphone, which is when he realized she was in bed with a new man, police said.
He burst into her third-floor bedroom and physically attacked Bush, who shot him in the head and torso, police said.
Bush fled, leaving the gun behind, but was captured in Harrisburg a few days later by U.S. marshals, police said.
Chief deputy prosecutor David Sunday could not immediately be reached for comment.
