Christopher Moon Kills Wife Cassandra Moore, Also Known as Cassie Clinger, Then Himself in Murder-Suicide Near Idaho–Wyoming Line, Deputies Say

A Wyoming man shot and killed his wife Wednesday morning before turning the gun on himself during a police standoff at a residence near the Idaho–Wyoming border, authorities said. No motive has been released.

Christopher Moon, 43, called 911 at approximately 8:06 a.m. and told dispatchers that he had murdered his wife, Cassandra Moore, 23, and planned to take his own life, according to ABC4.

Deputies with the Lincoln County Sheriff’s Office, along with SWAT teams, responded to the couple’s home in Star Valley near Freedom, Wyoming, along the Idaho border. Officers located Moon sitting inside one of two parked vehicles on the property and attempted to negotiate with him by phone. Despite repeated efforts to convince him to surrender, Moon fatally shot himself in front of law enforcement, authorities said.

A subsequent search of the residence revealed the body of Moon’s wife inside the home. Cassandra Moore was also known publicly by her maiden name, Cassie Clinger, which was used on her social media accounts.

The couple is survived by three children — two boys and an infant daughter. Authorities confirmed the children were not at the home at the time of the shooting.

Photos shared on social media show the couple celebrating their marriage in late July 2024. In the aftermath of the incident, Clinger’s mother, Cynthia, posted a statement in the Facebook group We Are Not Alone disputing any suggestion that her daughter died by suicide.

“I want you to know she did not take her own life,” she wrote. “Her life was taken from us and her beautiful kids. Rest in paradise my beautiful, beautiful girl.”

The We Are Not Alone Facebook group was created by Cassie Clinger, who used the platform to openly discuss her mental health struggles in an effort to help others facing similar challenges. In a post shared as recently as December 5, 2025, Clinger described ongoing struggles with depression, anxiety, postpartum issues, and mood instability, while expressing gratitude for the support she received from her psychiatrist, counselor, and members of the group.

Following Wednesday’s tragedy, tributes poured in from group members. One post read, “I barely knew Cassie. I found this group. It made me feel better, do better and want to be better. Cassie, you are amazing. You have touched lives way more than you know. You are already missed.”

A GoFundMe fundraiser established to support Clinger’s family states that her death has left “a profound void in the lives of everyone who knew and loved her.” Funds raised will go toward funeral and memorial expenses, as well as immediate and ongoing support for her children.

In addition, a Facebook auction group titled Caring for Cassie has been created, with donated items from businesses and individuals being auctioned to benefit her family.
