A Minnesota tree-trimming worker has been charged with second-degree manslaughter after authorities said his coworker died when a hydraulic grapple crushed his head during horseplay on the job. The incident occurred Thursday in Apple Valley, where Christopher Boone Crimmins, 34, was operating equipment mounted on a truck. His coworker, Tyler Anthony Lynch, 26, was on the ground clearing branches when the fatal incident occurred. Lynch was pronounced dead at the scene, according to authorities.
Investigators said the two men were watching the shadows cast by the equipment and began moving the grapple as though it were grabbing Lynch’s shadow. Authorities allege that Crimmins failed to monitor the actual machinery and Lynch’s position before opening and closing the grapple. The Dakota County criminal complaint states that the conduct created an unreasonable risk of death or serious bodily harm.

Fatal incident during tree-trimming work
The incident took place in Apple Valley, Minnesota, during a tree-trimming job on Thursday. Crimmins was working from the back of a truck and operating a boom, which is a movable mechanical arm used to handle tree material. Lynch was working on the ground and cleaning up branches. Police responding to a report of an incident found Lynch with severe head trauma and a significant amount of blood around him. Emergency personnel pronounced him dead at the location.
The criminal complaint identifies the two workers and describes the event as occurring while they were engaged in horseplay. Authorities have not alleged that the men intended for anyone to be injured, but prosecutors say the operation of the machinery nevertheless created a serious and foreseeable danger.
How the hydraulic grapple moved
According to the complaint, sunlight was casting shadows of both the grapple and Lynch onto the street. The men were reportedly playing with those shadows, and Crimmins allegedly moved the grapple so its shadow appeared to grab Lynch’s shadow. Investigators say he was focused on the shadows rather than the physical position of the grapple and his coworker.
Authorities allege that Crimmins then opened and closed the grapple while it was moving toward Lynch. The equipment itself, rather than only its shadow, reached Lynch’s head. A witness told investigators that the grapple appeared to hit or pinch Lynch before the fatal injury.
The complaint described the coworkers as “f,ing around” with the shadows cast by the equipment.
Evidence documented by investigators
Officers at the scene observed the grapple directly above Lynch and found blood on the machinery, according to the complaint. The physical evidence was consistent with the allegation that the grapple had made contact with Lynch’s head. Investigators also relied on a witness account describing how the equipment approached and struck or pinched him.
The complaint says Crimmins was not monitoring either the actual grapple or Lynch as he operated the boom. That alleged failure to watch the equipment and the person working nearby is central to the prosecution’s claim that the incident resulted from reckless conduct rather than an unavoidable equipment malfunction.
Manslaughter allegation and potential penalty
Crimmins has been charged with one felony count of second-degree manslaughter in Dakota County. Prosecutors allege that he acted negligently by consciously taking chances that created an unreasonable risk of causing death or great bodily harm to another person.
The charge is an allegation, and the case must proceed through the Minnesota court system. If convicted, Crimmins could face a maximum sentence of 10 years in prison and a $20,000 fine. The available charging documents describe the authorities’ account of the incident and do not establish a final determination of guilt.
Custody and next legal steps
Officials said Crimmins was being held at the Dakota County Jail after the charge was filed. Bail was set at $40,000 without conditions or $20,000 with conditions. The conditions attached to the lower bail amount were not detailed in the available account.
The case will continue as prosecutors and the defense address the manslaughter allegation in court. Further proceedings are expected to determine how the evidence, witness account and operation of the hydraulic grapple will be considered under Minnesota law.

Summary
