Merrillville, Ind. - Detectives hoping to solve two murders that occurred in northwestern Indiana 20 years ago say they'll need luck to finally close the cases.
Jeanne Marie Gilbert and Mary Margaret Gill were robbed and killed while working at separate Days Inn motels on March 3, 1989. Ballistics tests show the same gun was used in both killings.
Jasper County Sheriff Orville Perry says it's the only major crime his department hasn't solved.
Police have twice focused on a suspect, but DNA tests failed to match bodily fluids and tissue samples found at the crime scenes. Another potential suspect was ruled out when police learned he'd been in jail the day Gill and Gilbert died.
Merrillville Police Chief Joseph Petruch says he still considers the deaths an open case.
