Just three days after the record-breaking sale of a $14 million Sag Harbor Village home was reported, the identity of the mansion’s mystery seller has been revealed. Charles Ray Langston, a Miami-based hedge fund manager with a penchant for race cars, was named as the seller of the 8,200-square-foot home at 25 Shaw Road, the Post’s Jennifer Gould Keil reported. The identity of the buyer has not yet been revealed.
