Rivera went missing on 8 July after renting a pontoon boat at Lake Piru, about 50 miles northwest of Los Angeles, with her four-year-old son.
Officials had been searching for Rivera since 8 July, when she went missing after renting a pontoon boat with her four-year-old son.
Police said the Glee actress “mustered enough energy” to help get her four-year-old son back on the boat, but added that Rivera was not able to get back on herself.
Authorities are “confident” that a body found in Lake Piru is that of missing actor Naya Rivera.
