Dorothy Dottie Caylor, 41, of Concord, California, was last seen June 12, 1985. Dottie had a history of agoraphobia but had been making steps toward independence: she opened a separate bank account, rented a post office box, and told friends she planned to divorce her husband, entomologist Jule Caylor. Family members say she had confided about emotional and possible physical abuse; Jule denied those claims.

Jule told authorities he dropped Dottie at the Pleasant Hill BART station that day, but no one confirmed seeing her board a train. He later said he found her car at a different BART station the next day with her purse inside; family members found it odd she would leave behind a purse containing a medical card and a bee-sting kit. Jule moved to Utah and packed Dottie’s belongings within two weeks, repainted their home, and rented it out, and his statements about the events changed over time.

A letter postmarked from Indiana later accused Jule of murdering Dottie and gave a purported burial location, but no evidence has substantiated that claim and Dottie’s body has never been found. No one has been charged and the case remains unsolved. If anyone knew Dottie’s routines, friends, or movements around June 1985, does that information still exist that could help this investigation?
