Anna Constantin, 73, was murdered in her San Leandro, California, home sometime between June and August 1987. Her death was one of several linked to Franklin Lynch, the so-called Day Stalker, who targeted elderly women in home invasions that involved brutal beatings and robbery. Three of Lynch’s victims did not survive those attacks, including Constantin.

Lynch was arrested in October 1987 after a manhunt and was later convicted of first-degree murder, residential burglary and robbery. The jury found he personally inflicted great bodily harm on his victims and upheld special circumstance findings including burglary murder and robbery murder. In April 1992 he was sentenced to death. His case proceeded through appeals that included a claim he had been denied the right to represent himself, but the conviction and sentence remained in place.

Constantin’s killing formed part of a pattern that terrorized a community and underscored the vulnerability of elderly people living alone. Anyone who knew Anna, her routines, or has information about the events between June and August 1987 is urged to come forward.
