KIRKERSVILLE, Ohio — An Ohio village that lost its police chief in a nursing home shooting that left four people dead a year ago has unveiled a monument to serve as a tribute.

Police held a memorial on Saturday for Kirkersville Police Chief Steven Eric DiSario. The memorial included the unveiling of a bench honoring the police chief, who had only been on the job for a month.

DiSario, nurse Marlina Medrano and nurse's aide Cindy Krantz were killed in the May 2017 attack by suspected shooter Thomas Hartless.

Officials say Medrano had received civil protection orders against Hartless in connection with domestic violence charges. Hartless killed himself after the attack.

Kirkersville is a village of some 500 residents, about 25 miles (39 kilometers) east of Columbus.
