Tuesday morning, a Will County judge announced the trial will start on Monday, June 14.
Peterson is charged with murder in the death of his third wife, Kathleen Savio.
Peterson and his attorneys are happy with the trial date and say it gives them time to get ready.
"We look forward to the case proceeding to trial. We're gonna present a vigorous defense, and we look forward to a verdict in our favor," said George Lenard, Peterson's defense attorney.
Peterson is also a suspect in the disappearance of his fourth wife, Stacy, but he has not been charged in that case.
