Officials say that Armstrong had all four of her children in the minivan when she drove it into the Hudson River, the station reports. Armstrong's 10-year-old son Lashaun managed to slip out of the van by rolling down the power window, which was still functioning. Once he made it out, the boy swam back to the shore. A passerby found him soaking wet and took him to firefighters, authorities said according to WCBS. Seen here, Christine Santos of Newburgh, N.Y., a family friend of Lashanda Armstrong.
