Josh and Bianca Byrne were married on a New Hampshire farm the first weekend in October. Their new life together was cut tragically short during their honeymoon in Costa Rica, when Josh was swept away in a flash flood on Oct. 12. His body was found the following day, WESH reports. The couple was in a vehicle trying to cross a bridge in Playa Dominicalito when the flood hit; Bianca was able to swim to shore but Josh wasn't, NBC News reports. "It is with heavy hearts that we have concluded our search for Josh," says a statement released by his family. "After working around the clock, our search and rescue mission ended today with the recovery of Josh’s remains." A GoFundMe campaign has been set up for Byrne's family. (More flash floods stories.)
