A Minnesota tree worker is charged with second-degree manslaughter after on-the-job “horseplay” with heavy equipment killed his coworker.
Story Snapshot
- Prosecutors charged a boom operator after a hydraulic grapple crushed a coworker’s head.
- The complaint says the operator admitted moving the grapple while “messing around” with shadows.
- Officials allege culpable negligence, not a freak accident, under Minnesota’s manslaughter law.
- Tree-care is among the nation’s most dangerous jobs, with high fatality rates, regulators say.
What Prosecutors Say Happened
Dakota County prosecutors charged Christopher Boone Crimmins, 34, with second-degree manslaughter after a fatal incident in Apple Valley on August 20. The county’s release says a hydraulic grapple on a boom truck crushed 26-year-old Tyler Anthony Lynch’s head. Prosecutors allege Crimmins acted with culpable negligence that created an unreasonable risk. That standard focuses on careless actions that a reasonable person would avoid when using dangerous equipment at work.
The criminal complaint, as summarized in news reports, states Crimmins told police he and Lynch noticed the sun casting machine and human shadows on the street. Crimmins said he moved the grapple to make it look like the machine grabbed Lynch’s shadow. He then closed the grapple without realizing it was next to Lynch, and it crushed Lynch’s head. Lynch died at the scene, according to those reports citing the complaint.
Why This Is A Criminal Case, Not Only A Safety Case
Workplace deaths often lead to safety inspections and fines, but not always to criminal charges. Prosecutors file manslaughter when they believe conduct was so careless that it crossed a legal line. The county’s announcement signals they see more than a tragic mishap here. Their theory is that moving and closing a hydraulic grapple while “messing around” created an obvious, deadly risk, making Crimmins criminally responsible under state law.
Regulators also track patterns in this industry. The Occupational Safety and Health Administration says tree trimming and clearing work has a high rate of serious injuries and deaths. The agency launched a regional emphasis program after hundreds of inspections tied to fatalities or hospitalizations in recent years. The broader data show repeated hazards from heavy equipment, struck-by events, falls, and electrocution in tree care operations.
Safety Culture And The “No Horseplay” Rule
Tree work depends on strict controls because a small mistake can be fatal. Safety training in high-hazard jobs drills a simple rule: no horseplay around heavy machinery. The complaint’s account, if proven, describes a choice to use a grapple for a prank rather than for work. Prosecutors argue that decision created an unreasonable risk for anyone on the ground near the machine’s jaws. A jury will weigh that claim against the defense’s explanation of what the operator intended.
🚨 In a prank gone terribly wrong, a man has been charged with second degree manslaughter.

Many readers on both the right and the left see a larger failure when obvious rules are ignored and people die on routine jobs. They blame a system that rushes crews, skimps on training, or shrugs at safety until tragedy strikes. Government oversight can feel slow or reactive. Yet this case shows officials stepping in after the fact with criminal charges, while the same industry still logs high fatality rates year after year, according to regulators and researchers.
What Comes Next In Court And On Job Sites
Crimmins faces a second-degree manslaughter charge, which will move through the Minnesota courts. He is presumed innocent unless the state proves its case. The core legal fight will center on whether his actions meet the standard of culpable negligence. Separate from court, expect workplace safety investigators to review training, supervision, and site controls to decide if civil penalties or changes are needed to prevent another death like this one.
