Naya Rivera, well known for her role as Santana Lopez on “Glee,” is missing. The actress, 33, was last seen renting a boat on a lake with her 4-year-old son, the Ventura County Sheriff’s Office said. Hours later another boater discovered the child alone on the boat. “They contacted the rangers and we began an investigation and we have been actively searching for the mother since that time,” Captain Eric Buschow said during a press conference. Inside Edition Digital’s Leigh Scheps has more.
