The Michigan City police department says it will release facts about the cases, which go back as far as 1970. The project will start Jan. 17.

Authorities recently filed charges in the 2011 death of a 17-year-old girl, NeKeisha Hodges-Hawkins. Police say that case is a “shining example” of how the public and police can work together.

LaPorte County Prosecuting Attorney John Espar says new leads on cold cases can jump-start investigations. The Northwest Indiana Times says police will include the name and phone number of an investigator.
