The families of a mother and three children who drowned when their minivan rolled into Bunnell’s Pond six years ago have settled a multimillion-dollar lawsuit against the dealership that sold the woman the van. What began as a family picnic on a warm July 4 afternoon for 39-year-old Michelle McIntosh; her 2-year-old son, David Jr.; her nephew, 6-year-old Jayden Wilson; and 2-year-old Julia Boyd, the daughter of a family friend, turned into a traumatic event that shook the community.
