The Wilson County man accused of killing his in-laws by placing a bomb in their home last week pleaded not guilty to the charges against him in court this morning.

Richard Parker, 49, appeared in Judge John Wootten Jr's Wilson County courtroom shackled and cuffed to face his charges in the deaths of his mother-in-law Marion Setzer, 72, and her husband, Jon Setzer, 74. A special grand jury indicted Parker last week on two counts of felony first-degree murder, two counts of premeditated first-degree murder and one count of unlawful possession of a prohibited weapon.

The 15th Judicial District Public Defender's office will represent Parker, although a specific attorney has not been named.

Jon Setzer died at the scene of the explosion last week at his home on Vance Lane in Lebanon.

Marion Setzer died Wednesday at Vanderbilt University Medical Center.

Parker and his family live right behind the Setzers' home and shared a driveway. It was not immediately clear if any family attended the hearing.

Parker is being held in the Wilson County Jail on a $1 million bond. His next court date has been scheduled for April 8.
