KITTERY, Maine (AP)  Two families whose children were injured when a van owned by a Maine town crashed on Interstate 95 in New Hampshire are seeking financial damages for medical bills from the town.

The families are seeking damages from Kittery. An attorney for one of the families tells the Portland Press Herald “I think it’s probably a parent’s worst nightmare.”

Eleven summer campers were on the way to a water park on Aug. 10 when their van ran into a tree. Officials said the 21-year-old driver suffered a medical emergency before the wreck. An internal review showed the town failed to check his driving record.

A town attorney said the lawyers filed a notice to preserve a person’s right to sue and asked about the town’s insurance policy.
