County prosecutors charged Christopher Boone Crimmins with second-degree manslaughter after a fatal job-site incident.
Court filings say Crimmins admitted he was “f—king around” with the machine’s shadow before the grapple closed on Tyler Lynch’s head.
Tree work remains one of the nation’s deadliest jobs, with high rates of struck-by and fall deaths.
The case shows how a workplace tragedy can cross into criminal court when officials see culpable negligence.

Charge Filed After Fatal Grapple Incident in Minnesota

Dakota County Attorney Kathy Keena charged Christopher Boone Crimmins, 34, with second-degree manslaughter for culpable negligence after a deadly tree-trimming incident in Apple Valley on August 20, 2026, around 7 p.m. The county’s release says police responded and found coworker Tyler Anthony Lynch fatally injured at the scene. The filing states Crimmins operated a hydraulic grapple attached to a boom truck during the job. The charge marks the state’s claim that his actions created an unreasonable risk of death.

According to a local report that cites the criminal complaint, Crimmins told police he and Lynch noticed strong shadows on the street and began “f—king around.” Crimmins said he moved the grapple to make its shadow look like it was grabbing Lynch. He told officers he failed to realize the machine was next to Lynch, and when he closed the grapple, it crushed Lynch’s head. Lynch, 26, was pronounced dead at the scene, the station reported.

From Workplace Tragedy to Criminal Case

State law allows prosecutors to bring manslaughter charges when conduct shows culpable negligence that creates an unreasonable risk. The county’s statement links that standard to Crimmins’s alleged behavior with heavy equipment during active work. The filing does not claim intent to harm; it claims reckless or careless operation led to death. That is a common line in cases where officials believe normal safety rules were ignored or basic caution with dangerous machines broke down.

Such cases often move on two tracks. Safety regulators focus on what could have prevented the death and whether the employer met standards. Prosecutors look at individual choices that may have crossed into crime. The criminal complaint anchors its case on Crimmins’s own account and the sequence that ended with the grapple closing on Lynch’s head. A court will weigh the facts and decide if the legal standard for culpable negligence is met.

Tree Work’s Persistent Dangers and Public Concern

Federal workplace safety officials have warned for years that tree trimming is unusually deadly. A United States Occupational Safety and Health Administration directive shows a focused push on inspections in tree trimming and clearing because of frequent fatal and severe injuries. The agency documented hundreds of inspections tied to deaths or hospitalizations over several years and highlights common fatal events like struck-by incidents, falls, and contact with power lines.

🚨 In a prank gone terribly wrong, a man has been charged with second degree manslaughter.

These facts explain why many workers and families feel the system fails them. People on the right and left see a pattern: rules on paper, but not enough real safety on the street. They also fear that when leaders react, they do so after someone dies, not before. This case, now in a criminal court, reflects that gap. A routine job turned fatal. Prosecutors now seek accountability for a choice that, they argue, ignored basic care with heavy equipment.

What Comes Next and What It Means

The court process will test the charge and the evidence. The defense can challenge how events are described and whether Crimmins’s actions, while foolish, meet the bar for culpable negligence under state law. The outcome will not change a hard truth: high-risk work needs strict habits, clear roles, and steady supervision. When those break, families pay the price. Fair, steady enforcement before the worst happens is what most Americans say they want.
