A woman went missing in Niles in 1975 and now her cold case is opening back up.
Janis Sanders was last seen leaving her job at Pete’s Patio around midnight on July 20th.
Officials say that she was followed out to her car by her boyfriend, Gerald Casimer Libertowski, and was not seen again after that.
ABC 57 News reports that Libertowski was charged with the murder of Sanders, but charges were dropped.
Now, Detective John Moore has reopened the case.
Anybody with information is asked to contact Michigan State Police.
