'Glee' Star Naya Rivera Believed To Have Drowned In Tragic Accident, Investigators Say

"Glee" actress Naya Rivera is presumed dead after authorities spent more than a day searching for her at the California lake where she went missing, investigators said.

"We're presuming that an accident happened and we're presuming she drowned in the lake," Ventura County Sheriff Deputy Chris Dyer said at a news conference Thursday, according to CNN. Investigators are now focused on recovering 33-year-old Rivera's body from Lake Piru, where she had disappeared after renting a pontoon boat with her son.

"The goal is still to bring Miss Rivera home to her family," Dyer said. Rivera had not been found as of Thursday evening, the Ventura County Sheriff's Office announced on Twitter.

There have been occasional drownings through the years in the popular recreation area of the lake, about an hour’s drive from downtown Los Angeles, The Associated Press reported. 

Sheriff's Capt. Eric Buschow previously said at a press conference that Rivera and her young son rented a boat at the lake Wednesday afternoon and were seen going out onto the water together. Around three hours later, someone on another boat noticed a boat with a sleeping child alone in it and contacted authorities, who quickly launched a search for Rivera.

The child was wearing a life vest but was found alone on the boat, which also contained an adult life vest, according to the outlet. The child told authorities he'd gone swimming with his mother but she didn't come out of the water.

Rivera’s son, Josey, has been placed in the care of relatives and is healthy and safe, authorities previously said.

Rivera’s most recent Instagram post is a photo of her and her son, shared alongside the caption, “Just the two of us.”

The actress, who began acting on screen as a child, rose to fame as one of the stars of the Fox musical comedy hit “Glee,” appearing on the show from 2009 to 2015 as cheerleader Santana Lopez.
