1990 cold case closed
A St. Amant man pleaded guilty to manslaughter and second-degree kidnapping in court on Jan. 8.
Kenneth Lavigne, 50, of St. Amant was linked through a DNA analysis to a cold case from 1990, the murder of 38-year old Jeanie Lavigne, his uncle's ex-wife.
Jeanie's body was discovered on Dec. 17, 1990, by hunters near La. 431, sexually abused with her throat slashed. Kenneth admitted to kidnapping her the previous day from her home and bringing her to the Summerfield area.
Lavigne was linked to the case by new DNA technology. Though he refused to give a DNA sample, investigators had evidence that he was at the crime through a paternal DNA test from her son, Ryan Lavigne. He was arrested in 2013 in McComb, Miss.
Lavigne was sentenced to 21 years for manslaughter. He will appear in court on April 18 for his sentencing on second-degree kidnapping.
