The afternoon sun hung low over Apple Valley, casting long, sharp silhouettes across the asphalt. It was late August, the kind of golden hour that usually signals the tail end of a grueling shift, the sweet relief of approaching quitting time. High above the street, perched in the operator seat of a boom truck, 34-year-old Christopher Boone Crimmins gripped the controls. Down below, 26-year-old Tyler Anthony Lynch moved among the scattered debris, clearing fallen branches.
They were coworkers sharing a familiar rhythm. Days on a tree-trimming crew are defined by heavy machinery, roaring engines, and the grinding fatigue of physical labor. To break the monotony, crews often find small pockets of amusement. On this particular evening, those pockets turned fatal. Don't forget to check out our earlier post on this related article.
Against the pavement, the harsh light painted a striking contrast. The silhouette of the truck's massive hydraulic grapple—a heavy steel claw designed to hoist thick timber—stretched out beside the shadow of a human form.
Boredom met machinery. If you want more about the history of this, Al Jazeera provides an in-depth summary.
According to police charging documents, Crimmins and Lynch noticed the shadow play projected onto the street. What began as a spontaneous impulse to kill time morphed into a tragic game. Crimmins maneuvered the heavy boom, manipulating the steel jaws overhead so that their shadow appeared to playfully reach out and grab Lynch's shadow. It was a fleeting moment of dark humor on a quiet suburban street, a harmless illusion born of fatigue.
Except heavy steel does not care about shadows.
Safety protocols in industrial trades are written in blood, forged over decades of industrial accidents. Every commercial driver's license holder, every boom operator, is taught that industrial equipment is an extension of human error waiting to happen. Crimmins was the only one on the crew certified to operate the commercial vehicle, the one trusted with the controls. But familiarity breeds a dangerous brand of comfort.
When operators look at a screen, a mirror, or a shadow instead of the physical workspace, sensory disconnect occurs. Spatial awareness evaporates.
Crimmins stopped watching his coworker. His eyes tracked the flat, two-dimensional projections on the ground instead of the three-dimensional reality unfolding ten feet away. He closed the hydraulic grapple.
The transition from a game to a catastrophe takes a fraction of a second. A witness nearby watched in horror as the steel mechanism moved toward Lynch, closing with crushing force. There was no time to shout. No time to run.
When Apple Valley police arrived at the scene just after seven in the evening, the golden light had given way to the stark glare of emergency cruisers. Lynch lay on the pavement with catastrophic head trauma, surrounded by a pool of blood. He was pronounced dead right there, yards away from the tools of his trade.
Crimmins now faces a charge of second-degree manslaughter, caught in the legal machinery of the Dakota County justice system. He sits in jail, waiting for court dates that cannot undo a split-second lapse in judgment.
A family is mourning a twenty-six-year-old man who went to work and never came home. A coworker faces a future defined by an avoidable mistake. Out on the streets of Minnesota, the sun still sets, casting long shadows across the pavement, waiting for those who forget how quickly a game can turn real.
