BOONE, Iowa (AP) – A jury has resumed deliberations in the trial of a Georgia man accused of killing his former roommate in 2009. Jurors were scheduled today (Friday) to continue to work toward a verdict in the case against 55-year-old John Green, who is charged with first-degree murder in the death of 58-year-old Mark Koster, of Sac City. The case was sent to jurors Thursday after attorneys delivered closing arguments.

Defense attorneys say Green killed Koster in self-defense. But prosecutors argue that Green significantly outweighed Koster and therefore didn’t need to kill the man to defend himself. Koster was declared missing in 2010. His remains were later found buried in his basement after new owners began renovations.

Green’s second trial in the case began Monday. The first ended in a mistrial.
