KIRKERSVILLE, Ohio — Court records show the man authorities say gunned down an Ohio village police chief and two nursing home employees had a history of violence, including against the nurse who was among the slain.

The suspect, Thomas Hartless, 43, was found dead inside Pine Kirk Care Center.

Nurse Marlina Medrano, 46, nurse’s aide Cindy Krantz, 48, and Kirkersville Police Chief Steven Eric Disario, 36, were killed in the Friday attack.

State and local authorities said Saturday the investigation was continuing and they had no new information to release on the deaths in the village of some 500 residents, roughly 25 miles (39 kilometers) east of Columbus.

Spokeswoman Jill Del Greco, of the Ohio attorney general’s office, said investigators had more interviews planned and learning more about the connection between Hartless and Medrano is part of their efforts. Authorities have said they had been in a relationship.
