Evonitz killed himself last June after being surrounded by police in connection with a South Carolina rape.
Forensic evidence later linked him to the Spotsylvania county murders of Sofia Silva and sisters Kati and Kristin Lisk.
Since then, the FBI has received more than a dozen calls asking for help in determining whether their unsolved murders could be linked to Evonitz.
None have produced a definitive link, but investigators are still working.
