The thirty-three-year-old actress was confirmed as missing on the 8th of July on Lake Piru after renting a boat.

The news shocked the world...

And, to make the situation even worse, her 4-year-old son, Josey, was found alone at the scene of her disappearance.

Most of you will recognize Rivera from her role in the hit 2009 musical series, Glee.

The actress portrayed the role of the sharp-witted cheerleader, Santana Lopez.

Santana, who initially came across as cold-hearted and vicious, became a prominent character in the series...

And she went on to appear in most episodes across all of the 6 seasons.

Following on from her Glee success, Rivera ventured into the world of music.

In 2011, it was announced that the actress had signed a deal with Colombia Records to produce a solo album, and her debut single, "Sorry" featured the rapper, Big Sean, who she went on to have a brief romance with.

Sadly, her music career never really took off...

So instead, Rivera resorted back to her skills as an actress and went on to appear in a handful of different movies and TV series, including At The Devil's Door and Devious Maids.

But, in more recent years, Rivera had been focusing on something else...

With her now ex-husband, Ryan Dorsey, Rivera had a son, Josey, in 2015, and he had been the apple of her eye ever since.

Despite her divorce from Josey's father in 2018, Rivera had agreed to joint custody...

And she threw herself into motherhood, devoting most of her time to raising her son.

However, tragedy struck on the 8th of July.

While out vacationing with Josey along California's Lake Piru, Rivera went missing.

The actress had rented a pontoon boat on Wednesday afternoon...

But, 3 hours later, another boater raised the alarm after seeing the vessel drifting and Josey sleeping alone on board. The child was reportedly unharmed.

Upon arrival, the police found Rivera's car parked nearby...

And her lifejacket still onboard the boat.

It was assumed that Rivera and her son had been swimming in the lake...

The police suspected a " case of drowning."

Divers and helicopters were scouring the reservoir until darkness fell...

But at that point, no trace of Rivera was found.

The search proved to be difficult.

“There’s a lot of challenges in a reservoir this size, at times with visibility," Captain Eric Buschow, of the sheriff’s department, said on Thursday. “I don’t have details yet as to the depth of the area where the boat was found or what conditions they’re encountering out there."

Further details about her child's experience were released hours after her disappearance...

And it was utterly horrifying.

Josey's chilling words upon his rescue were released on Thursday last week.

According to TMZ, Rivera’s son had told the authorities that his mom had "jumped into the water but didn't come back up."

But, on Monday, a body was found...

And a press conference confirmed that the body, which was found floating in the lake following a 6-day search, was that of Naya Rivera's.

Her autopsy was completed shortly after the discovery.

Officials said she died by drowning. They also said: "There is no indication from the investigation or examination that drugs or alcohol played a role in the decedent’s death, but specimens will be submitted for toxicology testing."

People were devastated by the news.

And friends and former costars of the actress quickly took to Twitter to share their remorse and condolences.

Fans have been sending in messages of condolence...

And many have been remembering what a truly amazing person Rivera was.

And, shortly following from the tragic discovery, Rivera's fellow Glee cast members joined together at Lake Piru...

To make this photograph even more heartwrenching, the day in which her body was found was the 7th anniversary of the death of Cory Monteith.

It was known that Monteith and Rivera were close...

And Rivera had opened up in the past about how difficult it was for her following his tragic death.

Monteith's mom, Ann McGregor, has now spoken out since Rivera's death...

And she wrote some beautiful words on Instagram about her son's relationship with the actress.

She started by saying:

via: Twitter

"For the last 7 years, the 13th of July has shattered our hearts beyond repair. There aren't enough words to describe the pain we are feeling, we are truly heartbroken at the loss of @nayarivera."

She then spoke of her son's admiration for Rivera...

via: Twitter

"Naya, Cory loved you so so much. He cherished your friendship more than you will ever know. From the laughs you shared, to the strength you gave him when he needed it the most. Cory truly adored you."

She finished by saying:

via: Twitter

"He was in awe of your incredible talent, the way you gave everything you had to each performance; the slap in the auditorium was one of his favorite stories to share. You once said Cory was like a member of your family; you will always be a part of ours. We’ll carry you in our hearts forever. We miss you. Friends reunited for eternity."

Here's the beautiful post...

Rest in Peace, Naya. Our thoughts and condolences go out to her family during this awful time.

2020 has been an incredibly sad year so far.
