"A lot of different agencies are involved trying to sort through the mess," official says

Police investigating the fatal shooting of four people in Ohio believe the deaths are connected to a man who later drove to a cemetery and killed himself.

"We still unfortunately have three different crime scenes, a lot of different agencies are involved trying to sort through the mess, for lack of a better word," said Police Chief John Kuivila of the Newton Falls Police Department. "We are fairly confident that these homicides are related."

Police were alerted to a disturbance at a home in Newton Falls just after midnight Friday. Officers found a mother, a father and a juvenile shot dead in the home, Kuivila said. An additional juvenile in the home was unharmed.

As officers investigated the killings, they learned that Robert Brazzon , who lived in the area, was seen fleeing in a white car, police said.

About 4 p.m., Brazzon, 55, was spotted parked in a cemetery in the town, police said. After a brief standoff with authorities, he shot and killed himself, the police chief said.

Officers later found a 38-year-old woman believed to be the suspect's girlfriend dead from gunshot wounds in his home, CNN affiliate WJW reported.

The violence shocked the town of 5,000 people about 60 miles southeast of Cleveland.

"I think it's crazy. We don't know all the details, but you know, three of our neighbors are dead, and one of them was a teenage boy, and he was a good kid. You never think of this in Newton Falls," Jeff Culp told WJW.
