A confessed serial killer may have murdered women in Knoxville in the 70's and 80's, and the Knox County Sheriff's Office is looking for his potential victims.

Investigators say Jerry Marcus confessed to killing several women in the Knoxville area in 1984. He has already confessed and and been charged with the murder of Francine Davis, who was killed in October 1984. He lived in the city from 1975 until 1984, and played football at Knoxville College from 1975-79.

Now, KCSO's Cold Case unit is looking into any unsolved murders from that time to see if Marcus may have been involved. They are asking for the public's help in identifying any black females who disappeared in Knoxville or surrounding counties from 1975 until 1984.

If anyone remembers Jerry Marcus or any of his associates or places he frequented, or knows of any black females who disappeared during this time, they are asked to contact KCSO's Cold Case Unit at (865) 215-2243.

Marcus is currently in jail in Mississippi on other homicide charges. He has confessed to killing at least seven women in Alabama, Mississippi, and Tennessee from 1970 until 1987.
