The Israeli who was killed in a hit-and-run traffic accident in Massachusetts is Amnon Bogomolsky, of Moledet. Bogomolsky was accompanying his son on his Bar Mitzva trip to the United States.

The son was injured in the accident.

There were three adults and three children in the minivan that was hit. They were all traveling together. The two other children who were in the car were not hurt, but their mothers were injured. The casualties are hospitalized in Providence.

The hit-and-run crash occurred on the Sagamore Bridge in Bourne, southeast of Boston, on Wednesday, Massachusetts State Police said.

The police on Friday appealed to the public for help in locating a dark pickup truck that apparently triggered the fatal chain reaction crash, reported the website.

The pickup truck was merging from the Scenic Highway onto Route 6 eastbound when the left front side of the truck collided with a 2004 GMC Sierra, which was also heading eastbound and approaching the bridge, the State Police said.

The impact between the truck and the Sierra sent the Sierra across the median and into the westbound lanes of traffic where it slammed into the 2012 Chrysler minivan being driven by the Israeli man, State Police said, according to Boston.com.

The survivors are being assisted by the Jewish Alliance of Greater Rhode Island.

The driver of the Sierra, a 43-year-old Sandwich man, was also injured and was taken to South Shore Hospital for treatment of what State Police called serious injuries. His name was not released.

State Police are looking for the pickup truck and its driver.

 “We are seeking a dark-colored pickup truck, possibly with minor to moderate damage to its left front end or left side, which was last seen leaving the scene heading east on Route 6,’’ the State Police statement said.
