Following a shooting that ended in the deaths of four at the Pine Kirk Care Center in Kirkersville on Friday, authorities have identified the gunman as 43-year-old Thomas Hartless.
Officials say Hartless killed two female employees—Marlina Medrano, a nurse, and 48-year-old Cindy Krantzat, a nurse's aide—at the nursing home in Licking County.
Hartless then took two hostages, who escaped unharmed, before killing Kirkersville police chief Steven Eric Disario. The 36-year-old chief had been on the job for three weeks.
Licking County sheriff Randy Thorp says Disario arrived at the nursing home responding to reports of a man with a gun. When law enforcement arrived at the scene, they found Hartless dead with the two employees and Disario. It's suspected Hartless took his own life.
Ohio attorney general Mike DeWine says Medrano, whose age wasn't available, had a relationship with Hartless. She lived on the same street as he did in the nearby village of Utica.
A joint investigation is being conducted by the state Bureau of Criminal Investigation and the Adams County and Pike County sheriff's offices.
