Cloquet Man Sentenced To 39 Years After Murder Plea
A St.Louis County murder case that remained unsolved for 13 years is finally coming to a close. Joseph John Couture Jr. of Cloquet pleaded guilty Friday in the September 2000 murder of Trina Louise Langenbrunner.
According to the Duluth News Tribune, the 42-year-old Couture was sentenced to over 39 years in prison; 386 months on 2nd-degree murder charges, and another 86 months on additional convictions.
The guilty plea included charges of second-degree murder, witness tampering and abetting arson, says the St.Louis County Sheriff’s Office.
Langenbrunner, who was 33 at the time, was found stabbed to death near a gravel pit in St. Louis County. The murder occurred on September 3, 2000.
Sandra Couture, the wife of convicted John Couture, also pleaded guilty to first-degree witness tampering, first-degree aiding and abetting arson last March. The woman admitted to setting a fire to the house of a witness, which also destroyed the owner’s car and killed two dogs.
The St.Louis County murder remained a cold case until last year.
