 Two teenage brothers are believed to have drowned Sunday at a public recreation area in Sanford, Maine. The bodies of both boys were found overnight during a search of a local recreation area after the 17-year-olds did not return home for curfew. The chief medical examiner's office will perform autopsies to determine cause and manner of death as part of the ongoing investigation with Sanford police, though police say foul play was not to be believed to be a factor in their deaths.
