Betty Jo Grunzweig was 37 when she was murdered in her Oakland home in the Trestle Glen neighborhood on December 4, 1981. She was found stabbed to death; forensic investigators recovered skin from the perpetrator under her fingernails, a detail highlighted in the case file.

The investigation later linked her killing to Charles Jackson, known as The East Bay Slayer, a man connected to multiple murders across the San Francisco Bay Area between 1975 and 1982. Jackson had a long criminal history including burglary, rape and assault, and was apprehended on January 8, 1982. He was convicted of one murder and died in prison in 2002. Subsequent DNA profiling of biological material from crime scenes matched Jackson and tied him to Grunzweig’s murder, though he was never tried for this specific killing.

Are there any readers who knew Betty Jo, lived in Trestle Glen in 1981, or have information about that night?
