I wonder if Sherry's 1972 disappearance might have been connected with the May 1974 murder of a young woman also in Long Beach.
On May 20, 2013, a man named Gary Stamp (some sources state "Stump"), aged 61, was arrested in Texas. He confessed to a Long Beach California girl's May 1974 strangulation murder but was not certain of her name, which may have been Anna. She remains unidentified. Stamp was arraigned on June 12, 2013, in Superior Court but would die of cancer while in police custody.
