Nick, 13, was killed while riding his off-road motorcycle on trails near his grandparents\u2019 house on Hillbrook Lane when he crashed into a rope tied across the path. Nick, son of Kate Throckmorton and Rick Parisot of Nod Hill Road, subsequently died of neck trauma sustained from that impact. Wilton police have classified Nick's death as a homicide. At the press conference, Chief Lombardo said \u201cnew information\u201d in the case led police to Placentia, Calif., where the juvenile resides. The arrest was made by Wilton Detective Christopher Isidro. He was assisted by California detectives, Chief Lombardo said. The \u201caccused juvenile was taken into custody at approximately 7 p.m. (Eastern Standard Time) and charged with second degree manslaughter, according to Chief Lombardo. He will be extradited to Connecticut to be tried in Connecticut Juvenile Court, the chief said.
