NEW LONDON, Conn. (AP) Connecticut State Police say a 2-year-old boy was killed in a four-vehicle crash on Interstate 95 in Waterford.

The car in which Dacari Robinson was riding Sunday slowed with traffic that backed up due to previous accidents. Witnesses report that a truck driven by Gerard Dube of Swansea, Massachusetts, struck the car and two other vehicles. The 58-year-old Dube was not injured.

Robinson, of Meriden, was in a child safety seat. Police said Monday he was declared dead at the scene.

Two adults and a 9-year-old child in the car were injured and taken to a hospital.

About a half-hour later, six cars and a tractor-trailer were involved in an accident nearby on I-95. Police say seven people were taken to area hospitals.

Police said one passenger was unresponsive.
