LOS ANGELES – An autopsy report released Friday says “Glee” actor Naya Rivera raised her arm and called for help as she accidentally drowned while boating with her 4-year-old son on a California lake. Once his mother had helped him back on to the boat, the boy “noticed the decedent put her arm up in the air and yelled ‘help,’" the report from the Ventura County Medical Examiner says. Rivera “knew how to swim well,” the report said. Josey, Rivera's son with her former husband, actor Ryan Dorsey, was found sleeping and alone on the drifting boat later that afternoon. Another co-star, Mark Salling, who Rivera dated at one point, killed himself in 2018 at age 35 after pleading guilty to child pornography charges.

NEW YORK Naya Rivera, a singer and actress who played a gay cheerleader on the hit TV musical comedy Glee, was found dead Monday in a Southern California lake. What a force you were, wrote Glee co-star Jane Lynch on Twitter. She is survived by her parents, Yolanda and George; a younger brother, Mychal; a sister, Nickayla; and her 4-year-old son. Naya Rivera was a fierce talent with so much more to do and this is such a terrible tragedy. In the preface to her autobiography, Rivera wrote that motherhood had changed her life and given it perspective.
