Fatal Trick-or-Treat Trailer Crash in Mississippi Was 'Chaos'

— -- An adult and two children died Monday when a trailer carrying trick-or-treaters crashed into another vehicle in Newton County, Mississippi, authorities said.

The accident occurred around 7:45 p.m. when a Ford F250 rear-ended the trailer, which was being pulled by a Jeep Wrangler, according to the Mississippi Highway Patrol. The cause was unclear.

The dead victims were related, according to The Associated Press.

In addition to the fatalities, police said, there were multiple injuries in the crash.

"It was just chaos," Newton County Coroner Danny Shoemaker told the AP, describing the scene of the wreck on U.S. Highway 80 in Chunky, a town near the Alabama border, about 80 miles east of Jackson, Mississippi.

Three helicopters and multiple ambulances took the injured to hospitals, and some had life-threatening injuries, police said.

Those on board the trailer, including children and adults, were going house to house trick-or-treating, according to Staff Sgt. Andy West.
