LOS ANGELES (AP) – Authorities say they are searching for a second day for “Glee” star Naya Rivera, whose 4-year-old son was found alone on a boat they had rented together on a lake near Los Angeles. The Ventura County Sheriff’s Office says divers, drones and helicopters are being used to search Thursday for the 33-year-old Rivera on Lake Piru. Authorities say Rivera and her son rented a pontoon boat at about 1 p.m. Wednesday and her son was found about three hours later. Rivera played Santana Lopez, a singing cheerleader in the musical-comedy “Glee” that aired on Fox from 2009 until 2015.
