North Naples, Fla., - Wink News found out murder suspect, Robert moulton, and his wife Deborah had an ongoing feud with the victim and his wife.

"I encouraged the neighbors call the sheriff's office, tell them what's going on because this is escalating and some day its going to explode and they will need to know what's been building up to this," said neighbor Jean Heady-Spahr.

The build up to Sunday night's murder of Sergey Chepchugov was a decade-long feud with the man who allegedly shot and killed him, Robert Moulton and his wife Deborah.

Wink News uncovered new documents showing the Collier County Sheriff's Office visited both homes a total of 46 times in the past ten years.  Code enforcement officers visited nine times.  Finally, the feud got so bad, Chepchugov's wife Olga Kolesnikova filed a restraining order against Deborah Moulton in 2010 for what she says were repeated threats and attacks.

In a note to the judge, Kolesnikova said, "I don't feel safe in my home.  Deborah Moulton threatened me with a stun gun.  She has some kind of mental disorder and she is very angry, somebody has to stop her."

Wink News also uncovered an incident report from deputies in March of 2012.  In it, Chepchugov said during an argument that Deborah Moulton yelled at him "I'm going to kill you.  I'm going to put a bullet in your head."

Deputies say instead, it was her husband Robert who murdered Chepchugov.  An explosive finale to a feud neighbors had hoped would end peacefully.

"I'm heart broken for Sergey and Olga," said Heady-Spahr.  "This did not have to happen."
