Schepers was last seen attending a party with coworkers at a bar in Carpentersville.
ELGIN, Ill. (WLS) -- Elgin police and divers found a car connected to the decades-old cold case disappearance of a suburban woman on Monday.
Karen Schepers was just 23 years old when she disappeared in 1983.
A nonprofit group called the Chaos Divers set out to search for Schepers' car in the Fox River on Monday.
The team used sonar technology to locate the 1980 Toyota Celica northwest of the Slade Avenue boat launch, police confirmed later Monday evening.
Whether any human remains are in the vehicle is unclear, police said.
Chaos Divers, the Elgin fire and police departments and the Kane County Coroner's Office will work to remove it from the water on Tuesday. They were unable to remove the vehicle on Monday due to diving conditions.
Schepers was last seen attending a party with coworkers at a bar in Carpentersville. Neither Schepers nor her 1980 Toyota Celica were seen again, until now.
In January, detectives from the Elgin Cold Case Unit started a podcast in an effort to solve the case.
