Tina Marie Stimmell, 56, was shot and killed in her Mohave Valley, Arizona home on January 29, 2019, while she was sleeping. A mother of three who was also caring for three grandchildren, Stimmell’s death came at the hands of her husband, James Manker.

Manker later told investigators he intended the shooting as a mercy killing because of Stimmell’s kidney failure. That claim did not prevent prosecution. He was convicted of second-degree murder for the fatal shooting and was sentenced to 13 years in prison.
