BOONE, Iowa (AP) – A videotaped interview with Iowa police officers reveals that a Georgia man admitted he killed his former roommate in 2009. The video that aired in court Wednesday shows 55-year-old John Green talking with Sac City authorities in 2014 after they tracked him to Florida. Green is charged with first-degree murder in the death of 58-year-old Mark Koster, of Sac City.

During the interview, Green told police that he was watching a show on his computer when Koster came at him with a baseball bat, angry over how Green had prepared their dinner. Green said he then strangled Koster out of self-defense. Koster was declared missing in 2010. His remains were found buried in the basement of his home after new owners began renovations.
