BUCYRUS, Ohio (WTVN) -- Police in Bucyrus have a man they are calling a suspect in custody after four people were found dead over the last two days.

The man, who has not yet been charged, turned himself in Tuesday morning after two of the victims had been found on Monday. He then led police to two other bodies.

"This morning he came to us wanting to provide information about the events," said Bucyrus Police Chief David Koepke.

Police say all four victims died from blunt force trauma to the head.

"They died at the hands of violence," said Koepke.

Formal charges against the suspect, who hasn't been named, are expected later this week, according to Koepke.

He says the investigation has taken a toll on the small police department, so they've called in the Crawford County Sheriff's Office and Ohio Bureau of Criminial Investigation and Idenification for assistance.

"Whoever done this is a vicious person," Bill Chapman told our news parnters, ABC 6. "They hit my brother in the head with a hammer while he was down on the ground. There's blood splattered all over the house."

Koepke wouldn't discuss a possible motive and says they don't yet know what relationship the suspect and victims may have had.
