Jarvis filed a lawsuit in U.S. District Court in Detroit seeking $100 million in damages. She claims that the Oakland County prosecutor, sheriff department and state police withheld information about the case.

“The system has not only failed (my daughter) Kris but has failed all the victims of the monster who took our kids from it,” Jarvis said. “It’s time for (prosecutor) Jessica Cooper to step aside and let the Department of Justice investigate these cases.”

Jarvis’ Attorney, Paul Hughes, said it seems police and prosecutors have “fantastically bungled” the 35-year investigation, “… without not one arrest, with not one charge and with not one conviction after multiple child abductions.”

In addition to Jarvis’ daughter, 10-year-old Kristine Mihelich, three other children were killed between February 1976 and March 1977.

In May of last year, investigators said they found DNA evidence linking the four young victims. Their findings were turned over to a grand jury, which agreed to examine evidence and hear testimony in what could be a major step in identifying the killer.
