Katherine Mestites was 21 when she was killed in a house trailer near Mesa, Arizona, in autumn 1973. Her death occurred during a multi-state crime spree that eventually left seventeen people dead. Katherine had been staying in the trailer with two men later identified as Douglas Gretzler and Willie Steelman, and with a 19-year-old acquaintance, Robert Robbins.

Police say Gretzler and Steelman became convinced Robbins suspected them in other disappearances. On the evening of October 24, 1973, Robbins was strangled with an electrical cord. The next day, October 25, Steelman shot Katherine in the head while she knelt at a private altar conducting a séance. Their bodies were found on October 28, 1973. Gretzler and Steelman later confessed and were tried and convicted for killings in Arizona and California.

Does anyone have memories of Katherine, the trailer where she lived, or information about her final days?
