She didn't need magic lasso and she wasn't wearing her star-spangled costume, but Lynda Carter was still a hero on Wednesday afternoon.
The actress, best known for playing Wonder Woman in the 1970s TV show, was canoeing on the Potomac River when she spotted a woman floating in the water. She flagged down nearby boaters who called 911. After the woman was pulled out of the river, paramedics unsuccessfully performed CPR.
The body belonged to 47-year-old Helen Johnstone. Authorities believe that she may have fallen into the water while hiking on a nearby trail.
Carter did not comment to reporters as she quickly left the Potomac Boat Club.
