Robert Victor Frandsen who stabbed another man to death after catching him in bed with Frandsen's estranged wife - pleaded guilty Monday to a reduced charge.

In a hearing Monday before 3rd District Judge Frank Noel, Frandsen, 39 - originally charged with second-degree murder - pleaded guilty to manslaughter, a second-degree felony, and attempted aggravated assault, a Class A misdemeanor.Frandsen admitted being under extreme emotional distress on the morning hours of March 2 when he went to his home, 5324 S. Appian Way, and found Vance E. Boren, 31, in bed with Mrs. Frandsen, according to court documents and testimony.

A fight ensued, during which Boren was stabbed in the heart with a pair of scissors. Frandsen then fought with his wife, whom he threw to the floor and kicked in the head.

In allowing Frandsen to plead to manslaughter rather than murder, prosecutor Howard Lemcke explained to the court that he believed the probable outcome at trial would have been manslaughter.

Noel accepted the plea and set sentencing for Jan. 6.
