This is abomination: The man said he loved his girlfriend even though he almost severed her head and left her body to decay on the porch for days after she “pushed him too far.”

Shane Levi Cole Roberts, 46, from Billings, Montana, received an 85-year prison sentence on Friday, January 10, 2026, for the deliberate homicide of his 52-year-old girlfriend, Genna Rae Moncada-LaCombe, whom he nearly decapitated in August 2024. Neighbors reported a foul odor from their Sioux Lane apartment on August 24, 2024, leading police to discover her decomposing body wrapped in blankets, towels, and a shower curtain on the front porch, while Roberts hid in a closet with a dog. He pleaded guilty after evidence including bloodied knives, a hatchet, hammer, and phone photos of her body in a bathtub surfaced, and he admitted to his mother from jail that she “pushed him too far.”​

Crime Evidence

Autopsy revealed multiple stab and blunt force wounds, including a neck cut nearly severing her head.
