Minnesota man charged in death of co-worker crushed by hydraulic grapple in prank gone wrong

The man is accused of saying he was trying to make the shadows look like a truck’s grapple had his co-worker’s head but didn’t realize where it was before he closed the claw.

A Minnesota man is accused of crushing his co-worker’s head with a hydraulic grapple while the pair were “f------ around” during a tree-trimming job, killing the 26-year-old co-worker.

Christopher Boone Crimmins, 34, is charged with second-degree manslaughter, accused of operating a truck-mounted hydraulic grapple that closed on his co-worker’s head.

According to a criminal complaint filed Friday in Dakota County, Crimmins told police that he and Tyler Anthony Lynch, 26, were working together in Apple Valley on Thursday afternoon when the two started “f------ around.”

The men noticed the grapple’s shadow and Lynch’s shadow on the ground, and Crimmins began moving the grapple to make it look like it was grabbing Lynch, the complaint says. Crimmins was watching the shadows rather than Lynch himself, it says, and didn’t realize the grapple was closing in on Lynch’s actual head until it crushed it.

Police found Lynch on the ground “with a large amount of blood around his body and a significant injury to his head,” according to the Dakota County Attorney’s Office.
