Suffolk County police 6th Squad detectives are investigating a three-car crash that seriously injured a woman last night in Holtsville.

Richard Sougstad, 33, of Coram, was driving a 2012 Dodge Ram eastbound on the Long Island Expressway, approximately 1,000 feet west of exit 63, when he allegedly attempted to change lanes and crashed into a 2003 Hyundai Sonata driven by John Capuano, at approximately 7:15 p.m. The crash caused the Dodge to overturn. The Hyundai then struck a 1998 Nissan Maxima driven by Capuano’s son Christopher. Christopher Capuano then drove the Maxima to a parking lot at a nearby hotel.

Linda Capuano, 54, of Astoria, Queens, a passenger in the Hyundai, suffered serious injuries. Her husband John Capuano, 53, also of Astoria, sustained non-life-threatening injuries. Sougstad also sustained non-life-threatening injuries. A 2-year-old female passenger in the Dodge sustained minor injuries. All of the victims were transported to Stony Brook University Hospital. Christopher Capuano, 31, of Medford, was not injured.

The investigation is ongoing. Detectives are asking anyone with information about the crash to call the 6th Squad at 631-854-8652.
