Details of Disappearance
Susan was last seen on April 25th 1986 in Modesto, California leaving her family’s residence as she had plans to stay with friends in the Carmel area of California. She was last sighted at the now former greyhound bus depot on 10th Street and G Street. According to reports, Susan did not board a bus but was seen getting into a van described as being a full sized olive green 1977 Ford. This occurred during the day. Susan was never seen again.
Susan was reported missing later on. A person was questioned by authorities regarding Susan’s disappearance soon after she vanished because some of her possessions such as her diary, address book, and articles of her clothing were located at this persons home. The person was released due to lack of evidence. This individual has not been publicly named.
Authorities suspect that Susan was abducted and possibly murdered. The “speed freak killers” Wesley Howard Shermantine Jr. and Joseph Herzog are considered possible suspects in Susan’s case. They went on a killing spree that went through the 1980s and 1990s. They killed several females and may have had more then 15 victims.
The men are also considered suspects in the 1993 California disappearance of Phillip Martin, the 1986 California disappearance of Sylvia Standly, the 1988 California abduction of Michaela Garecht, the 1988 California disappearance of Gayle Marks, and the 1982 California disappearance of Ruth Leamon. The bodies of other victims have been found and Shermantine has cooperated with authorities to reveal the locations of their victims. Herzog committed suicide after he heard that his partner was doing this. Shermantine is currently on death row.
Authorities do not know if the men had anything to do with Susan’s abduction but it’s possible as she vanished in the time that they were killing people and she fits their MO for victims. Susan’s case remains unsolved and foul play is suspected.
