Connie R. Heerdt, 30, was found murdered on January 15, 1991, in a Rockford, Illinois parking lot behind Doyle’s Circle K Lounge. A utility worker discovered her body at about 10:00 a.m.; the Winnebago County Coroner ruled the cause of death asphyxia due to manual strangulation. She was partially clothed when found and there were no immediate clues about a suspect.

Heerdt was last seen the same morning at approximately 2:30 a.m., when a police officer reported seeing her walking near 7th Street and 12th Avenue. Reports say she had ties to a high-risk lifestyle, including drug involvement and association with a rough crowd, but also that she was trying to get her life back on track and remained close to her family. The case remains unsolved and local authorities have appealed to the public for information.

If anyone knew Connie, her movements that night, or has information about people she associated with, please contact the Winnebago County Sheriff’s Office or local Crimestoppers.
