The Florida man accused of killing his roommate in Sac City back in 2009, and then hiding the body, has pleaded not guilty.
John Green entered a written plea of not guilty in Sac County District Court. Prosecutors say Green choked his former roommate Mark Koster to death in Koster's Sac City home in 2009 before leaving town.
Koster's body was discovered during renovations in 2012.
Green was arrested last month in Florida and is being held without bond in the Sac County Jail.
His next court date is scheduled for June 2.
