COLLIER COUNTY, Fla.- The murder of a Naples man after a decades-long dispute with his neighbors is back in the spotlight.

The widow of Sergey Chepchugov is suing Deborah and Robert Moulton for more than $15,000 in civil court.

In the lawsuit, Olga Kolesnikova said she and her daughter suffered damages after the murder of her husband. The suit also says Deborah Moulton was negligent and a direct cause of Chepchugov's death.
