Diane Martin, 48, was killed by a single gunshot fired from outside her home at 84 Ricker Street in Waterloo, Iowa, on the night of September 10, 2018. She was taken to UnityPoint Health‑Allen Hospital and later pronounced dead; an autopsy confirmed a single gunshot wound as the cause of death.

Martin’s death followed another fatal shooting in the family: her 22‑year‑old son, Shavondes Martin, was found shot to death in an alley in May 2018. Authorities said they were uncertain whether Diane Martin was the intended target and could not definitively link her homicide to her son’s, and they indicated they do not believe the two killings are related. Anyone with information about the shooting at 84 Ricker Street is asked to come forward.
