In the early morning of February 12, 2024, Sam Allan Miller, 73, and his wife Marjorie Jeanne Valentine, 72, were found dead from gunshot wounds inside their Phoenix home near 35th Street and Campo Bello Drive. Both were described as lifelong Phoenix residents, active in their church, and Sam was a U.S. Navy veteran. Responding officers arrived about 5:15 a.m. after a domestic violence call.

Their 38-year-old son, Jim Miller, placed the call and initially told police his father had shot his mother and then himself. Detectives found inconsistencies in that account; a roommate in the home was unharmed. Under questioning Jim Miller confessed to shooting both parents and was arrested and booked on two counts of first-degree murder. Court documents note a history of mental illness, including schizophrenia and bipolar disorder, that he had not been taking prescribed medication, and that he admitted to using methamphetamine the night of the killings. A prior 2018 incident is mentioned in which he had pointed a gun at his mother and a roommate.

The investigation remains active. Does anyone have information about the family or the neighborhood that could help investigators?
