Broomfield resident John O’Neill had made it out of rehab, he was in stable housing, he was sober, and he had finally got a job he loved doing: tree work. But 15 minutes into his first day, the 33-year-old found himself fighting for his life, he gripped the edge of a wood chipper as blades whipped through his legs below. Later, in a helicopter on the way to the hospital, O’Neill “technically died.”
