 According to Sanford Police, officers were called at around 11 o'clock on Sunday night after the two 17-year-old siblings hadn't returned home after going to swim at Springvale's Holdsworth Park. Police located their vehicle at the park and found the two brothers dead in the water. Authorities say that foul play isn't suspected and an investigation is ongoing. For Maine Public Radio, I'm Sandra Harris, in for Bill Johnson.
