Incident Overview
In late August, a tree-trimming crew in Apple Valley, Minnesota, was involved in a fatal accident when a hydraulic grapple mounted on a truck closed on the head of 26-year-old Tyler Anthony Lynch. The criminal complaint filed by Dakota County alleges that Christopher Boone Crimmins, 34, and Lynch were “f—ing around” and watching the shadows cast by the equipment and the worker. While focusing on the shadows, Crimmins maneuvered the grapple so its silhouette appeared to grab Lynch’s shadow, but the machine itself moved toward Lynch’s head and crushed it. Police and a witness reported seeing the grapple pinch or hit Lynch’s head, and officers found him on the ground with extensive blood and a severe head injury. Lynch was pronounced dead at the scene.
Legal Actions and Official Responses
Crimmins, the only crew member licensed to operate the hydraulic grapple, was charged with one count of second-degree manslaughter involving culpable negligence. The Dakota County Attorney’s Office set bail at $40,000 without conditions or $20,000 with conditions, and noted that a conviction could carry up to 10 years in prison and a $20,000 fine. Attorney Kathy Keena expressed “deepest condolences” to Lynch’s family and praised the Apple Valley Police Department for its investigation. Judge Adam Johnson scheduled Crimmins’ next court appearance for early September.
Workplace Context and Safety Concerns
The incident occurred during a routine branch-clearing job. Hydraulic grapples are powerful, truck-mounted devices used to lift and move large debris, and only operators with a commercial license may control them. The complaint suggests that the workers’ informal “shadow-playing” diverted attention from the equipment, creating an “unreasonable risk” that led to the fatal outcome. Authorities emphasized that negligence in monitoring such machinery can result in severe injury or death.
