UNIONVILLE, Ohio - An act of violence ends in more violence as the man who stalked and murdered a school teacher is found dead.

Mahoning County Career and Technical Center teacher Stacey Sutera was ambushed and shot to death early Wednesday outside her Canfield condo by 64-year-old Robert McLaughlin, a man who stalked her for years.

Ever since the early morning shooting, police began to cast a wide net for the Painesville man.

An off duty Madison Township police officer discovered McLaughlin's body and his rented van around 1:20 p.m. Thursday afternoon at the tiny Harpersville Cemetery in Unionville, Ashtabula County.

He was found with an apparent self-inflicted gunshot wound to the head, slumped over his mother's grave.

"We believe that Robert McLaughlin was aware that law enforcement was hot on his tracks," explained Canfield Police Chief Chuck Colucci. "And eventually drove to a cemetery and that's where he decided to take his own life, one gunshot wound to the head, with a small caliber handgun."

Wednesday night police discovered a note in McLaughlin's belongings, saying suicide was an option. They believe he killed himself Thursday after feeling the pressure from so many police departments working together.

"The FBI, the U.S. Marshals, our Mahoning Valley Law Enforcement Task Force," said Chief Colucci, listing the agencies who assisted his department. "And if it wasn't for all of us coming together and working together, we wouldn't have been able to put this type of pressure on our suspect."

Police believe McLaughlin was the man who killed Stacey Sutera but they are also looking into other people of interest.

"There [are] other subjects of interest as far as contributing roles but our suspect is the deceased," said Chief Colucci.

He said McLaughlin's suicide brings to close a very sad crime in the city of Canfield.

"I can't express enough grief for the family of our victim," he said. "That's been ringing through all of our hearts through this entire time and now that we're back from Ashtabula and our suspect's deceased, starting to settle in a little bit and we feel a lot of grief for that family. And we're going to make sure they have every right as a victim."

Chief Colucci says victims advocates from the FBI and Ohio Attorney General's office are in contact with Sutera's family.
