On Monday, the Ventura County Sheriff's Office confirmed that they believe the body found earlier in the morning to be that of Naya Rivera, who disappeared at California's Lake Piru last week.
Rivera, 33, starred in all six seasons of the hit show "Glee," and was also known for her roles in "At the Devil's Door," "Step Up: High Water" and her arc in "Devious Maids."
Ventura County Sheriff Bill Ayub told reporters the medical examiner would make the official identification and an autopsy will be performed. Rivera’s family has been notified of the discovery.

We are forever grateful for the indelible contribution she made to ‘Glee,’ from the first episode to the last," 20th Century Fox TV and Fox Entertainment said in a statement obtained by The Associated Press.
Lea Michele, who starred alongside Rivera, shared a handful of images on her Instagram Story. One photo was a solo shot of the actress, who played Santana Lopez, while another photo showed a handful of ladies, one bearing resemblance to Rivera's iconic ponytail, looking out at a beach.
