Amy Osowski, 49, was shot to death in her Mesa, Arizona, home on June 5, 2023. The killing occurred in the 600 block of East 1st Place, near University and Mesa drives, and was witnessed by her adult son.

According to the witness, tensions escalated after the son’s stepfather, 43-year-old David Osowski, made statements that God told him he was not part of the family. The argument reportedly grew more heated, and David Osowski retrieved a handgun from inside the residence and shot Amy multiple times in the face. Mesa police arrived to find David Osowski walking out of the house; he was taken into custody without resistance and Amy was pronounced dead at the scene. David Osowski was booked on one count of first-degree murder.

Are there witnesses or neighbors who saw or heard anything that evening who can provide additional details?
