HUTCHINSON ISLAND, FL (AP) – Authorities say a Chester County couple vacationing in Florida with their six children drowned after they were caught in a rip current while swimming. Investigators say 51-year-old Brian Warter and 48-year-old Erica Wishard of Downingtown and two of their mostly teenage children were caught in a rip current on Hutchinson Island, along Florida’s southeast coast. A rip current is a fast-moving column of water that flows away from the shore toward open water. Officials say swimmers caught in one should remain calm and then swim parallel to the shore to escape the current. The children broke free, but the parents were unable to swim out of the current.
