Betty Lammers, 81, was found dead at her Phoenix home on June 20, 2023, alongside her 78-year-old husband William Lammers. Both had been fatally shot in what investigators later classified as a double homicide. Authorities concluded the couple’s adult son was the perpetrator and that he then died by suicide at the scene, so there was no arrest or criminal trial.

The case was closed after investigators identified the son as the sole person responsible for the shootings and his subsequent self-inflicted death.

Did anyone in the Phoenix area know the Lammers family or have information that could shed light on their circumstances leading up to June 20, 2023?
