KIRKERSVILLE, OH (WCMH/AP) – An armed man gunned down a new village police chief on a street and then killed two employees in a nearby nursing home, where he later was found dead, a sheriff said. No nursing home residents were injured.

The slain police chief, Steven Eric DiSario, had headed the Kirkersville Police Department for only about three weeks, Licking County Sheriff Randy Thorp said. DiSario was shot on a street near the Pine Kirk Care Center, and the two employees and the gunman were found dead inside, Thorp said.

Family members identified Thomas Hartless, 43, as the shooter. His cousin, who did not want to go on camera, told NBC4’s Shawn Lanier that Hartless did not live in Kirkersville. His girlfriend worked at the nursing home where the shooting happened.

DiSario, 38, was a father of six children, with a seventh on the way, the sheriff said. Services will be held at Schoedinger Funeral Home on East State Street, where DiSario’s body was taken Saturday.

Thorp called it a hard day for all.

“We’ve lost a police officer. It’s just a tragic event,” he said. “I guess the only peace of mind is that the threat is over.”

Officials identified nurse Marlina Medrano and nurse aide Cindy Krantz as the deceased.

NBC4’s Courtney Yuen confirmed Medrano was Hartless’ girlfriend.

By early afternoon, flowers and flags appeared in an impromptu memorial outside the village police hall.

DiSario was responding to a report of a man with a gun, and his last radio communication said he had the man in sight, Thorp said.

Responding officers found DiSario on the street and then investigated a report of a gunman at the nursing home, Thorp said.

Some nursing home residents barricaded themselves during the shooting, but none of them was injured, he said.

Police weren’t immediately able to identify the gunman and were trying to determine what, if any, relationship he had with the nursing home, Thorp said.

The shooting closed down the main street in the village, which was flooded with police officers from several surrounding agencies and with ambulances. The village of about 500 residents is roughly 25 miles east of Columbus.

Kirkersville mayor Terry Ashcraft released a statement Saturday morning:

“Acting Chief DiSario was with The Village of Kirkersville for a very short period of time. We are deeply saddened by the tragedy that has unfolded resulting in the death of Acting Chief DiSario while protecting the citizens of our Village. Our thoughts and prayers are with his family, and the families of all victims of this senseless tragedy. We would like to thank all of the law enforcement agencies, and other local government offices and officials for their assistance and support.

Local schools on lock down

Kirkersville Elementary School was on lock down while police investigate.

“It was scary because I just put my kid on the bus and I didn’t know where he was going,” one parent told NBC4. “They didn’t call us till like 15-20 minutes later.”

“Any time, even if it’s not your school, just for it to be so close, you know, they have to be pretty vague on what it is, just let you know that everything is locked down, so, uh, that was a little alarming because all schools are locked down, so you’re not really sure what’s going on,” another parent told NBC4.

Response from local police agencies

Thorp shared his own thoughts Saturday afternoon. “Yesterday Hell paid us a visit,” he began.
