The incident occurred on Thursday evening, August 20th, at around 7 p.m. local time. Officers from the Apple Valley Police Department responded to reports of a serious injury involving Lynch, who was found on the ground with significant head trauma and blood around his body. Despite the immediate arrival of emergency services, Lynch was pronounced dead at the scene.

According to details released by Dakota County officials, Crimmins and Lynch had only recently arrived at the worksite when the incident transpired. In statements given to the police, Crimmins explained that he and Lynch had been “playing with shadows” while he operated the hydraulic grapple. He stated that Lynch had been picking up branches when they both noticed the shadow projected by the grapple. Lynch apparently encouraged Crimmins to manoeuvre the equipment to create the illusion of the grapple gripping Lynch’s shadow.
In a shocking turn of events, while Crimmins was allegedly engaged in this playful activity, he opened and closed the grapple, inadvertently crushing Lynch’s head. Crimmins claimed that he was not watching the grapple or Lynch during this critical moment. It has been reported that a witness present at the scene observed the grapple moving towards Lynch, remarking that it either hit or pinched his head, with evidence of blood found on the grapple above where Lynch lay.
Crimmins was taken into custody and is currently held at the Dakota County Jail, facing a bond set at $40,000 without conditions or $20,000 with conditions. His next court appearance is scheduled for September 10th. If convicted, he faces a potential maximum prison sentence of ten years, according to the complaint filed against him.
The community has reacted with shock and grief over the tragedy, as Lynch was described on social media as someone who had been working in professional tree services since 2021. Family members expressed their devastation on platforms like Facebook, with one relative, Charles Gallagher, sharing a heartfelt message that read, “Absolutely no words. Tyler is my stepbrother. Sending all the prayers possible for my stepdad.”
Kathy Keena, the Dakota County Attorney, has extended her condolences to the family of the deceased. She stated, “My deepest condolences to Mr. Lynch’s family members and friends, and all those affected by his death,” reflecting the sorrow felt by many in the community over this unfortunate event.
As investigations continue, police have reported that Crimmins denied being aware of any mechanical problems with the grapple equipment prior to the incident. The case has attracted significant attention, raising concerns about safety protocols and the responsibilities of operators when handling heavy machinery.
This incident underscores the tragic consequences that can stem from seemingly harmless interactions on job sites, highlighting the need for stringent safety measures and training to prevent such occurrences in the future. As the legal process unfolds, the families affected by this tragedy are left to navigate their profound loss while seeking justice for Tyler Lynch.
