On the morning of March 3, 1989, 24-year-old Margaret Peggy Gill was found murdered at the Days Inn in Merrillville, Indiana. She had been working the overnight auditor shift to help pay for business college tuition. Her body was located in a vacant hallway; investigators determined she had been sexually assaulted and killed by gunshot wounds to the head. The motel’s front desk cash drawer had been forced open and robbed.

Ballistics later tied the killing to another attack that same day: Jeanne Gilbert was abducted from a Days Inn in Remington, Indiana, and shot to death. Testing showed the same .22 caliber firearm was used in both murders, creating the profile of an assailant later dubbed the I-65 Killer or Days Inn Killer who targeted motel clerks along the Interstate 65 corridor.

Decades later preserved DNA from these scenes and from a 1990 survivor’s sexual assault were reexamined using investigative genealogy, producing a lead that identified a suspect. That suspect, named by authorities in 2022 as Harry Edward Greenwell, had died in 2013. Does anyone have information about Peggy’s last shift or the Days Inn in Merrillville that might help fill gaps in the timeline?
