Lisa Diane Parkin was 11 years old when she was murdered on November 7, 1973. The killing was part of a mass murder at the home of her parents, Walter and Joanne Parkin, in Victor, California, a small community near Acampo.

Two criminals, Douglas Gretzler and Willie Steelman, invaded the Parkin home during a multi-state crime spree. Lisa and her brother Robert were found shot to death in the master bedroom. Their parents and five other victims were discovered bound and murdered in a walk-in closet, bringing the death toll at the house to nine.

Gretzler and Steelman were arrested shortly after the killings, charged with multiple counts of murder, and later convicted. The brutality of the attack devastated the local community and remains a somber part of the Parkin family’s memory.
