The death of "Glee" actress and singer Naya Rivera was ruled an accidental drowning, it was announced Tuesday.
Rivera's autopsy findings "are consistent with a drowning and the condition of the body is consistent with the time that she was submerged," the Ventura County Medical Examiner's Office said in a news release. There was no indication that drugs or alcohol played a factor, but a toxicology test is expected.
The 33-year-old's body was discovered at Lake Piru in Ventura County on Monday morning after days of searching, officials concluded.
The discovery came amid an extensive search for the missing "Glee" star that included sonar, dogs and divers scouring the lake, in addition to cabins and outbuildings in the surrounding area being searched. Rivera went missing July 8 after going on a boat ride in the lake with her 4-year-old son. She disappeared while swimming in the reservoir northwest of Los Angeles, sheriff's officials said. Her son was found asleep on a pontoon boat that had been rented some three hours earlier.
The Ventura County Sheriff's Department said at an afternoon news conference Monday that based on where the body was discovered, and the physical characteristics of the body, that it was determined to be Rivera.
No life jacket was discovered with the remains, however an adult-sized life jacket was discovered on-board the pontoon.
The body appeared to have been in the water for several days, officials said. Prior to the autopsy findings, investigators said it was likely that she drowned accidentally, and her body became tangled in vegetation before her remains floated to the top Monday, accounting for why she hadn't been found sooner.
"I can't make any sense of what happened," said Ventura County Deputy Chris Dyer. "We just know that we found a 4-year-old on a boat, and he said that his mother never got back in."
"So, right now, we're viewing this as a tragic accident."
In a heartbreaking update to how investigators pieced together what had happened, Ventura County Sheriff Bill Ayub said Rivera likely used her last bit of strength to save her 4-year-old son, Josey Hollis Dorsey, based on what the child had told them.
“She must have mustered enough energy to get her son back on the boat, but not enough to save herself,” Ayub said at a news conference.
Her son had told investigators Rivera had pushed him back onto the boat before he saw her go under the water, investigators said.
The day after she went missing, authorities stated they believed the 33-year-old actress was presumed dead and they had shifted search efforts to a "recovery mission."
Monday marked day six of the search and recovery mission.
Exactly seven years earlier, on July 13, 2013, Rivera's "Glee" co-star Cory Monteith was found dead of an overdose in a Canadian hotel.
In January 2018, "Glee" co-star Mark Salling, who Rivera had dated for a time, killed himself following a child pornography conviction.
Rivera portrayed cheerleader Santana Lopez on "Glee" for several years.
"Glee" castmates and other celebrities began expressing their heartfelt sadness over the announcement.
20th Century Fox also released the following statement:
“Naya Rivera was a fierce talent with so much more to do and this is such a terrible tragedy. We are forever grateful for the indelible contribution she made to GLEE, from the first episode to the last. Our hearts are broken and our thoughts go out to Naya’s family, friends and young son.”
