"Particular cruelty" has brought an Iron Range teenager several more years in prison for killing his roommate and burning the body in an abandoned ore mine pit.

Dylan B. Gilbertson, 19, of Hibbing was sentenced Wednesday to a 35-year term for the death of 20-year-old Jaysen Greenwood in May. With credit for time served in jail since his arrest, Gilbertson will be imprisoned for roughly 23 years before he's eligible for supervised release.

Gilbertson pleaded guilty in November to second-degree murder and was sentenced in St. Louis County District Court in Virginia. His term is almost 10 years longer than state guidelines call for because "the victim was treated with particular cruelty," according to the state statute.

Because the defendant agreed to the longer sentence, the state didn't convene a grand jury to consider a first-degree murder charge, said County Attorney Mark Rubin.

Greenwood's charred remains were found by someone walking in the Mott Pit area of Mountain Iron on May 19. Investigators believe Greenwood died less than 24 hours earlier.

Greenwood had been stabbed, beaten and strangled in a dispute that apparently started in the apartment the men shared. A partial knife blade remained in his chest. The state Bureau of Criminal Apprehension identified him through his fingerprints.

A 16-year-old female roommate told authorities that the men had been fighting because Gilbertson accused Greenwood of stealing electronics from him, according to the case file.
