A 10-year-old boy escaped out the window of a sinking car after his mother drove the vehicle off a pier Tuesday night about 70 miles north of New York City, authorities said. Lashaun Armstrong swam to shore and was picked up by a passing motorist and brought to a nearby fire station in Newburgh, New York, said Fire Chief Michael Vatter. Lashaun told police his mother, Lashanda Armstrong, had driven the car off a pier. Police divers later found the bodies of Armstrong, 25, and an 11-month-old girl, a 2-year-old boy, and a 5-year-old boy. Police investigators said they believe Armstrong drove the car off the pier intentionally following a “domestic disturbance” incident that may have involved Armstrong’s husband, Jean Pierre.
