Warwick A Chester man charged two weeks ago with manslaughter and criminally negligent homicide was arrested again this week for violating his probation on a criminal mischief charge. Adam R. Moghaddam, 20, was the driver two weeks ago in a crash that killed his friend, Richard Rudy, also 20, of Warwick. Warwick Police Lt. Thomas Maslanka said the State Police Accident Reconstruction team was recreating the accident to determine just how fast the 1990 Nissan driven by Moghaddam was traveling. Blood samples from Moghaddam also have been submitted to a police lab to determine if drugs or alcohol were factors. Maslanka said a few eyewitnesses to the crash told police the car was speeding. Maslanka said a “speed contest” had occurred shortly before the crash. The occupants of the car engaged in the “contest” with Moghaddam have cooperated with police in this investigation. They did not witness the crash, however. Rudy died instantly when he was ejected from the Nissan. Moghaddam and Rudy were heading west on County Route 1 at about 9 p.m. on Sept. 30, when police said Moghaddam lost control and the car crossed the double yellow line just past Blooms Corners Road near Horseshoe Lane. It rammed into a 2002 Subaru driven by Carol Faison of Basking Ridge, N.J. Faison and her passenger were treated for minor injuries and released, according to police. A witness to the crash pulled Moghaddam from the burning Nissan. Police arrested Moghaddam when he was released from Westchester Medical Center on Oct. 3. He was charged with second-degree manslaughter and criminally negligent homicide, both felonies. After being arraigned Monday night, Moghaddam posted bail on Tuesday and was arrested again for violating his probation in connection with a fourth degree criminal mischief arrest in the Village of Florida. He was sent to the Orange County Jail.
