YAPHANK - The Long Island Expressway has reopened following an investigation into Wednesday's fatal multi-vehicle accident.

Officials say one person was killed and 33 were injured in a massive, multi-vehicle crash on the Long Island Expressway on the Shirley-Yaphank border.  The LIE was closed in both directions near exit 68 following the crash, however, it has since reopened.  Police say in all, 35 vehicles were involved in the crash.

Police say that the accident began when a truck, driven by 42-year-old Raymond Simoneau, of Rockingham, Vermont, slammed into a number of cars in front of him, setting off a chain reaction crash. In the end, the truck and three cars were on fire while 31 other cars were damaged.

The accident left a 68-year-old Blue Point woman dead and at least one other person remains in serious condition at a nearby hospital.

The truck was carrying Hurricane Sandy debris from Eisenhower Park in East Meadow to Riverhead at the time of the accident, according to officials.

Authorities say Simoneau is cooperating with police during the investigation.
