Benson, N.C. — Three members of a family were killed in a single-vehicle accident that shut down half of Interstate 95 in Johnston County overnight Saturday.

Judith Days, 62, of Ocala, Fla., was driving home from a Thanksgiving trip to Massachusetts, along with her husband, children and grandchildren.

Troopers said she was likely distracted before the van struck a sign on the right side of I-95 South near mile-marker 79. Days over-corrected when she pulled the van back onto the road, causing it to overturn several times. The van came to rest upright in the median.

Two children were killed: William Harper, 4, who was in a booster seat, and Jessica Harper, 15, who was ejected from the van. Days also died in the accident.

Three other occupants suffered non-life-threatening injuries and were transported to Betsy Johnson Regional Hospital: the children's mother, Colleen Harper, 38; Russell Days, 62, the husband of Judith Days; and Paul Arthur, 40, the son of Judith Days.

All three were treated and released by Sunday afternoon.

A dog in the van was also killed, troopers said. Another dog was being cared for by animal control until the family was ready to take it home.

I-95 South was shut down for nearly 3 hours while the wreckage was cleared. Traffic was detoured around the scene.

Jessica was not wearing a seat belt. Of the adults, only Arthur and Judith Days were wearing seat belts.

Troopers said drugs or alcohol were not a factor in the crash.
