Police have identified the man accused of killing three people at a nursing home in Ohio on Friday morning.

An officer on scene confirmed to FOX 28 that 43-year-old Thomas Hartless is the man suspected of shooting Kirkersville Police Chief Steven Eric DiSario and two employees at the Pine Kirk Care Center in the small community of Kirkersville.

The shooter killed 36-year-old Kirkersville Police Chief Steven Eric Disario who was responding to a 911 call from the Pine Kirk Care Center, Fox 28 reported. Investigators later found three bodies inside the home including the killer, Licking County Sheriff Randy Thorpe said.

When the shooter got close the nursing home, he took two passers-by as hostages; they were both later released, unharmed.

A motive for the shootings was unclear.

Authorities said at a Friday press conference that a search warrant will be executed for the shooter’s home in Utica and that search warrants were already executed for two of his vehicles.

The last radio transmission from Disario informed dispatch that he had the gunman in his sights. When backup units arrived, they found Disario's body in the street.

The names of the other two victims, both women who worked at the nursing home, have not been released.

Disario had six children and another baby on the way, Thorpe said.

Thorpe set another news conference for later Friday afternoon.

Witness Jeffrey Griffin said he heard the gunshots while dropping his kids off at a babysitter’s house. He said people “took off running” from the Pine Kirk Care Center, and he was “pretty stunned.”

Kirkersville is about 24 miles east of Columbus.

The shooting closed down the main street in the village, which was flooded with police officers from several surrounding agencies and with ambulances.

The state Bureau of Criminal Investigation is leading the probe into what happened.
