In the spring of 2006, the life of 23-year-old Tonya Jo Goble-Studer, a female, came to a brutal and tragic end in the small community of Union Pier, Michigan. Seeking refuge from a volatile and abusive marriage, she had moved in with her mother, Vicki Dewey, and her stepfather. Tonya had taken her two children with her, a decision that would ultimately infuriate her estranged husband, Gary Studer. On April 28, 2006, a day that would forever be marked by violence, Tonya’s fears for her life escalated. She placed a desperate call to 911 from a nearby school, pleading for help and expressing her terror that Gary was going to kill her. Tragically, her plea did not result in immediate police intervention.

Gary Studer, a man with a history of violence and a severe brain injury from a past car accident, became enraged when he discovered Tonya and their children were gone. He tracked her down to her mother’s home in Chikaming Township. What followed was a violent confrontation that culminated in the shooting deaths of both Tonya and her mother. When police officers did arrive at the residence, they were met with a horrific scene. Gary Studer was found covered in blood, in the presence of his two young children. Inside the home, the authorities discovered the bodies of Tonya and Vicki Dewey.

Gary Studer was promptly arrested and faced a litany of charges, including two counts of first-degree premeditated murder, first-degree felony murder, first-degree home invasion, and felony firearm charges. During the trial, the prosecution presented the chilling 911 recording of Tonya's last call, a haunting testament to her final moments of fear. Studer’s defense attorneys argued that a combination of alcohol, drugs, and his pre-existing brain injury rendered him incapable of controlling his actions. However, a Berrien County jury was not swayed by this defense and found him guilty on all counts. The case cast a harsh light on the handling of domestic violence calls and led to a revision of the 911 dispatch policy, a change born from an unspeakable tragedy that claimed the lives of two women.
