In 2002, author Bette Nunn theorized that Judy could have been responsible for the 1977 murder of Ann Harmeier, a 20-year-old student who attended Indiana University. Harmeier disappeared on September 12, 1977, and her body was found five weeks later in a cornfield, approximately five miles from where her car was found. She had been raped and strangled. Her death was similar to Terry Chasteen's: both women were kidnapped from highways by someone who offered them help, both were raped and strangled with items they had on them, and both were dumped in isolated areas in Morgan County. However, an Indiana State Police review of jail records showed that Judy was imprisoned in the Marion County Jail on the day Harmeier disappeared. It has been theorized that the information about Judy's incarceration could have been wrong, however. Harmeier's mother, who died in 1983, believed Judy murdered her daughter. Harmeier's murder remains unsolved and is still being investigated by cold case detectives.
