BOONE, Iowa (AP) - A Georgia man admitted killing his former roommate in 2009, saying he did so to protect himself, according to a videotaped interview with Iowa police that aired during the man’s trial Wednesday.

Prosecutors rested their case against John Green after calling investigators and state officials to the stand and showing video of Green’s conversation with Sac City authorities in 2014 after they tracked him to Florida. Green, 55, is charged with first-degree murder in the death of 58-year-old Mark Koster, of Sac City.

During the interview, Green told police 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 choked Koster out of self-defense and later dragged his body to the basement, where he covered it with kitty litter bags and left a note saying Koster had left to visit a friend in Florida.

Koster was declared missing in 2010. His remains were found buried in the home after new owners began renovations.

Jonathan Thompson, associated state medical examiner, testified about his experience performing the autopsy. He said what was left of Koster appeared “mummified” and that the only way to identify him was through dental records. His death was ruled a homicide caused by strangulation, but Thompson said he came to that conclusion only after seeing Green’s interview with police.

Green’s original trial was held in Webster County because his attorney argued that pretrial publicity would make it impossible for Green to receive a fair trial in Sac City. The same argument was used against holding the second trial in Fort Dodge. The first ended in a mistrial.
