NEWBURGH, N.Y. (AP) — A 10-year-old boy escaped through the window of a minivan and swam to shore to get help just as his mother drove the van into New York's Hudson River, killing herself and three other children, police said Wednesday. Lashanda Armstrong, 25, drove the minivan into the river off a boat ramp in the city of Newburgh about 8 p.m. Tuesday, shortly after a domestic incident, police said. The van went into the river just six blocks from where the family lived in this faded city about 60 miles north of New York City.
