RIP

Patrick Muldoon showed off his humor and energy in the last video he ever sent his sister ... even pulling out his old high school chant in the heartbreaking clip.

The actor's sister, Shana Muldoon Zappa, shared the video to Instagram late Wednesday night ... revealing her brother sent it on Saturday during a preview opening of the new Los Angeles County Museum of Art.

Check out the clip ... Muldoon excitedly films a painting of St. Ignatius of Loyola -- before breaking out into a chant.

Zappa explains her bro was a fan of the saint ... and, he went to Loyola High School -- so, the chant is a nod to his football-playing days way back when.

"Storage Wars" star Brandi Passante is honoring Darrell Sheets after his shocking suicide ... saying she's at a "loss for words" in an emotional Instagram post.

She reacted to the heartbreaking news of the A&E star's death Wednesday, saying her heart hurts for his loved ones ... and urged people who are struggling to get help.

She pleaded, in part, "I would like to say to everyone, if you are struggling, if you feel hopeless or like no one cares. I assure you they do!! You are not alone. Please reach out for help." Brandi's emotional message was paired with a selfie with Darrell as well as BTS images of them together.

Celeste Rivas' family says they're "devastated" by newly released autopsy findings ... and confirm they won't attend an upcoming hearing for D4vd, who's charged with her murder.

The Rivas Hernandez family, through their attorney, tells TMZ ... they're suffering "profound emotional pain" after reviewing the report into their daughter's killing ... describing the details as "horrible and gruesome." They're now asking for privacy, understanding and patience as they process the tragedy.

The family also says Celeste's parents, Jesus and Mercedes, will not attend D4vd's hearing scheduled for Thursday.

We broke the story ... the Los Angeles County Medical Examiner had actually determined Celeste's cause and manner of death months ago -- back on December 9 -- but the findings were kept under wraps due to a court-ordered security hold requested by LAPD during the investigation.

Now that the info is public, L.A. County M.E. Dr. Odey Ukpo is speaking out ... saying it's "unfathomable" the grieving family had to wait so long for answers.

Ukpo emphasized transparency is critical not just for accountability, but to help communities understand and prevent future tragedies.

The M.E.'s report ultimately ruled Celeste's death a homicide caused by multiple penetrating injuries from unspecified object(s).

Police in Arizona are investigating claims "Storage Wars" star Darrell Sheets was being bullied online before he committed suicide.

The Lake Havasu Police Department tells TMZ ... "We are aware of these cyberbullying accusations and that is a part of the active investigation."

We broke the story ... Darrell was found dead in his Lake Havasu home Tuesday morning and police say it appears he died from a self-inflicted gunshot wound to the head.

The Los Angeles County Medical Examiner is speaking out about being muzzled for months in the Celeste Rivas murder case, TMZ has learned.

The M.E. says Celeste's cause and manner of death was determined way back on Dec. 9 but the information was only made public on Wednesday because there was a prior court order initiated by the LAPD that had been preventing them from releasing their findings.

In a statement, Dr. Odey Ukpo, says ... "After several months, I am grateful this information can now be released, not only to the public, but also to the grieving family enduring loss. It is unfathomable they have had to wait this long to learn what happened to their daughter."

"The transparency of the information contained in our findings and reports is essential for empowering the community to make informed changes to affectively reduce fear and allowing the community to take informed action," he added. "Making the Department’s information publicly available is not just about accountability, it is about social justice and prevention."

Rene Nezhoda says people online mercilessly cyberbullied Darrell Sheets before his death ... and, he hopes this will serve as a wakeup call to all the online menaces out there.

Nezhoda spoke about Sheets -- who cops found dead in his home early Wednesday morning -- in a video ... admitting the two had their run-ins because they both competed intensely against each other.

Nezhoda says, deep down, he and Sheets were friends ... and he's sad his pal's gone now. He also says he hopes cops will look into cyberbullying claims Sheets made about others as they investigate his death.

Lee Najjar -- best known to "The Real Housewives of Atlanta" fans as Kim Zolciak’s elusive "Big Poppa" sugar daddy -- has died at 68.

The wealthy Atlanta real estate investor passed away Saturday, April 18 -- tragic news confirmed by his daughter Katelin via a slate of IG Story pictures of them together and an emotional tribute. Lee's cause of death is unknown.

"Storage Wars" star Darrell Sheets is dead, TMZ has confirmed.

Lake Havasu Police in Arizona tell TMZ ... Sheets apparently died from a self-inflicted gunshot wound to the head.

Celeste Rivas' cause of death has just been revealed ... and the medical examiner in Los Angeles says she was killed by multiple penetrating injuries with unspecified objects, and her death was ruled a homicide.

The M.E. says there are "2 penetrating wounds of the torso with smooth edges that may represent sharp force injuries. The wound -- [3/4 inch length and 1.5 inches deep] -- on the upper abdomen penetrates the liver, and the wound on the left chest -- [9/16 inch length and 2 inches deep] penetrates one of the left intercostal spaces, with disruption of the adjacent ribs' cortical surfaces."

It's interesting that the M.E. uses the word "may," which is something the defense will jump on.

It should also be noted that the M.E. says there were "multiple superficial linear abrasions on the right dorsal hand." It does not say whether or not these could be defensive wounds.

The M.E. also says that her left ring and pinky fingers were amputated, but the body diagram shows that her right pointer finger with the "Shhh" tattoo was intact.
