In early February 2014, a domestic disturbance escalated into a tragic series of events that left three people dead, including Sherri Pachello. The incident began to unfold when Pachello went to pick up her daughter, Alisha Johns, from the Frederick home of her husband, Cimmeron Johns. The couple had been experiencing marital problems, with a history of domestic violence. Concern for her daughter's safety likely prompted Pachello's intervention that fateful evening.
What followed was a desperate attempt to flee from an escalating threat. Witnesses reported seeing Cimmeron Johns chasing the vehicle carrying his wife and mother-in-law. The chase came to a grim end in Weld County, where the bodies of both Sherri Pachello and Alisha Johns were discovered the following day. The women had been murdered, their lives cut short in a final, violent encounter. The search for the perpetrator immediately focused on Cimmeron Johns, who had disappeared after the chase.
The manhunt for Cimmeron Johns led authorities to a Thornton apartment complex. There, he was found barricaded inside one of the units, leading to a tense standoff with law enforcement. The situation escalated further when gunfire was exchanged between Johns and the officers on the scene. Ultimately, the standoff concluded with Johns taking his own life. The investigation that followed revealed the depth of the domestic turmoil that had preceded the murders, including a recent severe assault on his wife. A woman named Rosanne O'Donnell later pleaded guilty to being an accessory to the crime for assisting Johns after the murders.
