ROCKINGHAM, Vt. — A man whose body was found in a box truck on the side of Rockingham Road (Vermont Route 103) Friday evening died from a gunshot wound, according to Vermont State Police.
The Vermont Chief Medical Examiner’s Office completed the autopsy Sunday on Roberto Fonseca-Rivera, 44, of Boston. The cause of death is a gunshot wound of the head and neck, and the manner of death is homicide, Vermont State Police said in a news release Monday.
Fonseca-Rivera, an employee of Katsiroubas Bros. produce of Massachusetts, was in Vermont making deliveries in a company vehicle, police said. He was last seen leaving Rutland and traveling south on Route 103 Friday at approximately 12:15 p.m.
Evidence indicates Fonseca-Rivera was shot inside the vehicle, according to Vermont State Police spokesman Adam Silverman.
According to police, investigators think he was shot between 1 and 1:30 p.m., on Route 103 near where his body was found. Police responded to a check-the-welfare call at around 5:45 p.m. Friday, which brought them to Fonseca-Rivera’s truck on the side of the highway between Williams and Lower Bartonsville roads.
Police said the initial investigation indicates this incident was an isolated one, but the investigation is ongoing.

According to a 2018 news release from the U.S. Attorney's Office for the District of Massachusetts, Fonseca-Rivera was sentenced to one year and one day in prison, along with three years of supervised release, for his role in a cocaine distribution operation on the South Shore.
