NEWBURGH - Officials say an upstate Orange County mom drove straight into the Hudson River, killing herself and her three children. Police say Lashanda Armstrong?s 10-year-old son escaped through the window of the minivan as Armstrong drove into the Hudson River. Officials say the boy swam to shore, and a woman driving by picked him up and took him to the fire department. By the time rescuers pulled the van out, Armstrong and her 5 and 3-year-old sons and 11-month-old daughter were dead. Police say Armstrong was involved in some sort of domestic incident right before the deadly plunge.
