A Sandwich teen was found guilty of motor vehicle homicide by negligent operation Tuesday following a trial in Barnstable District Court. Judge Joan E. Lynch sentenced 18-year-old William B. Putnam IV of 51 Service Road in Sandwich to a one year sentence in a house of correction, suspended for a probationary period of four years, according to a release from the Cape & Islands District Attorney's Office.
The charge stems from a fatal crash at the intersection of Route 132 and the Route 6 east on-ramp in Barnstable on November 30, 2012. The jury found that Putnam failed to stop at a red light, causing a collision with a second car. Luke Marshall, 24, of Brewster, the passenger in the other vehicle, died as a result of the crash.
In addition to the four year probation, Putnam is required to complete 500 hours of community service.
His driver's license will also be suspended for 15 years, according to the DA's office.
Assistant District Attorney Michelle L. Groff was the prosecutor on the case.
