GOSHEN TOWNSHIP, Ohio - A Berlin Center man is indicted on nearly 80 counts of stalking and identity theft after years of sending harassing letters to people he knew.

Mahoning County has indicted Jamie Longnecker with 79 counts of stalking, intimidation, identity theft and violating a protection order.

Police say he not only sent pornographic and threatening letters to an acquaintance and a former employer, he also used those victims's homes as return addresses on other harassing letters.

"You just can't use individuals' names and logos and names of businesses," said Mahoning County Sheriffs Detective Patrick Mondora. "You just can't do that, it's identity fraud."

The letters date back several years. Detective Mondora says he's never seen anything like it.

"This individual was just fixated on this person and it got to a point where we felt, and the prosecutors felt, that her life was in danger," Detective Mondora said.

But Goshen Police Detective Kevin Stratton has seen it. He investigated similar charges against Longnecker dating back to 2008.

"We served a search warrant in '09 in his house and obtained over 25 bags of evidence that aided us in the investigation," said Detective Stratton.

The same woman and same former employer were targets, as well as their families. Off camera, the business owner, who employed Longnecker, told 21 News that the harassment was "detrimental" to his business.

He believes Longnecker obtained names of people off the business's Facebook page to harass the customers. Police reports say some victims believe their names were taken off a family member's obituary.  "They would be afraid to walk out to the mailbox," said Detective Stratton. "It would involve their whole families."

Longnecker pled guilty to two counts of menacing by stalking in Goshen Township. He was sentenced to two years probation, which he would still be serving during these most recent allegations.

Longnecker also had to serve six months in a mental health facility. Police say the harassing letters picked up almost immediately after he pled guilty.

"He pled guilty and was sentenced to probation December 10, 2010," said Detective Mondora. "The victims started receiving their new letters the next day, on the 11th."

Detective Mondora hopes the new charges will produce several years of jail time for Longnecker, pointing out that the harassing letters haven't stopped.

"At yesterday at the indictment the female victim's father handed me more envelopes they were still getting," he said. "Several individuals, including the female victim and family members, received letters with poison ivy leaves in it. Recently."

Karen Longnecker, Jamie's mother, contacted 21 News to say her son is not guilty of the charges. She says her family has also received threatening letters including one this week that contained poison ivy. She said police are targeting her son but when we asked what motive they would have for doing so she said she didn't know.
