RIP

The clinic where Joan Rivers' throat procedure turned deadly ... just filed a plan to make a slew of major changes to avoid getting shut down by the feds.

According to docs obtained by TMZ ... Yorkville Endoscopy is responding to flaws found by the Department of Health and Human services ... by making several upgrades to its procedures.

Among the changes:
- Stricter procedures to credential physicians and observers who are admitted into operating rooms
- The clinic has to perform a full assessment of a patient's weight, allergies, and medical history before administering Propofol
- Supplemental oxygen should be routinely used and immediately available for patients sedated with Propofol
- Anesthesiologists must check vital signs at least every 5 minutes for patients sedated with Propofol
- Unscheduled drills to resuscitate patients using defibrillators/crash carts will be run 4 times a year

Most of the changes relate directly to problems the agency found at the clinic while investigating Joan's death. The Dept. of HHS has signed off on Yorkville's plan.

Yorkville officials had been given a January deadline to get this done ... or the feds could have closed down the clinic.

Floyd Mayweather finally sat down with the LAPD for a 2-hour interview Wednesday, telling detectives he desperately tried talking his good friend, rapper Earl Hayes, out of killing himself.

Law enforcement sources tell TMZ ... Floyd confirmed the story first reported on TMZ ... that he was on FaceTime Monday morning with Hayes when the rapper walked away from the phone, into the bathroom and pumped multiple bullets into his wife, Stephanie Moseley.

Floyd told detectives after Hayes shot his wife, he came back to the phone and continued talking with Floyd. The boxer says Hayes said he was going to shoot himself and Mayweather pleaded with him ... to no avail.

As for what happened before shots rang out ... Mayweather acknowledged he was talking with Hayes about Stephanie's infidelity, but denies riling the rapper up.

Detectives asked Floyd why Hayes called him at 7 AM. Mayweather said it was because they were best friends and Hayes was trying to say goodbye.

Floyd Mayweather wants to be seen -- going out to a major celebrity event in L.A. for the 3rd night in a row -- but he REFUSES to talk about the murder/suicide he witnessed on FaceTime.

The boxer -- along with model Liza Hernandez -- went to the Runway Wonderland 2014 fundraiser last night to benefit children in need ... and was asked repeatedly about the incident involving his friend Earl Hayes.

But despite the fact he was at another event that was heavily covered by media, Floyd's lips were sealed about the incident. As we previously reported, he's been "less than willing" to cooperate with police as well.

There was so much weed in the house where a rapper shot his famous wife Monday in a murder-suicide, it required an armed guard to protect the stash as it was taken to a police lab.

Law enforcement tells TMZ it's a significant twist to the tragedy. We broke the story ... rapper Earl Hayes shot and killed his wife, VH1 star Stephanie Moseley, in the bathtub and then turned the gun on himself. This all happened as Floyd Mayweather listened on FaceTime as his friend repeatedly fired shots.

We're told cops found nearly 10 pounds of high-grade marijuana inside the L.A. apartment. It's an enormous amount of pot ... way more than for personal use. The estimated street value approaches $40K.

As we reported, Mayweather was riling Hayes up during the call, telling him he should divorce his wife because she was habitually unfaithful ... allegedly having flings with various singers and rappers including Trey Songz. Hayes flew into a rage, walked into the bathroom and began firing.

For the second night in a row, Floyd Mayweather decided to deal with the murder/suicide involving his friend Earl Hayes by sitting courtside at a NBA game.

Floyd -- along with model Liza Hernandez -- went to Staples Center and sat on the hardwood to watch the Lakers take on the Sacramento Kings ... laughing and smiling as if nothing was wrong.

Shocking ... considering Mayweather witnessed the horrific incident on FaceTime -- and you'd think a public place like a NBA game would be the last place he'd want to be.

As we previously reported, cops want to speak with Mayweather about the incident. We're told police have reached out to Floyd's people ... but they've been "less than willing" to cooperate.

Meanwhile, Kobe Bryant walked on to the court last night with a shirt that read "I Can't Breathe" ... as a tribute to Eric Garner.

Mary Ann Mobley -- one of the first Miss America winners to make it big in show business -- died on Tuesday in Beverly Hills after a long battle with breast cancer.

Mobley won the 1959 Miss America pageant before breaking into Hollywood. She appeared in several big movies in the '60s ... including "Girl Happy" and "Harum Scarum" with Elvis Presley.

In 1967, Mary Ann married actor and TV host Gary Collins ... who passed away in 2012.

She went on to star in tons of TV shows through the '70s and '80s -- among them ... "Love, American Style," "Fantasy Island," "Diff'rent Strokes," and "Hotel."

Mobley was also famous for her humanitarian work with children in Cambodia, Ethiopia, and the Sudan.

Mary Ann's family says she will buried next week in her native Mississippi. She was 75.

Rapper Earl Hayes had thoughts of suicide long before killing his wife and himself on Monday -- back in 2010 he recorded a song with lines like, "I could just kill us both, go out with a smash."

The song was called "Suicide" and it was part of a mixtape Hayes put out called "The First 48" (which also happens to be an A&E show about murder investigations).

It's pretty eerie ... in the song Hayes describes almost exactly the tragedy with his wife, VH1 star Stephanie Moseley:

Shoot your girlfriend or when you get surrounded by cops.
F**k the real life shoot it out and do your time on the spot.

Make a family crying with your girl and their hearstses.
Take somebody with you who really didn't deserve it.
Show everybody that life just ain't perfect.
And when you get mad, it's time to close curtains,
Cuz this song is for you.

In another song ... "Introducing Hayes" ... he raps, "I want respect even if I got to die for it. Even if my family gotta stand over my casket and cry for it."

Floyd Mayweather whipped his friend Earl Hayes into a frenzy over his wife's infidelity ... to the point Hayes gunned her down ... and now the LAPD wants to sit the boxer down for questioning ... multiple sources tell TMZ.

TMZ broke the story ... Floyd was on FaceTime with his rapper friend Monday morning when the shots were fired. Now we're told, Floyd was telling Hayes he should leave his wife, Stephanie Moseley -- a well-known backup dancer and star of VH1's "Hit the Floor" -- because she was bad for his career.

As we reported, Hayes was distraught over what he believed was repeated infidelity, including a fling he said Stephanie had with Trey Songz.

One Mayweather source says Floyd challenged Hayes, saying he was weak for not leaving her.

At that point, as Floyd was on FaceTime, Hayes went off and said he was going to gun down Stephanie. We're told when the boxer realized Hayes was going to shoot Stephanie, he begged Hayes not to go through with it.

Our law enforcement sources say Hayes went into the bathroom and fired 10 to 12 shots as Stephanie was taking a bath. We're told she was hit multiple times.

Neighbors who heard the shots called the LAPD and cops rushed to the scene, but when they got to the door they heard another shot and retreated. That shot was Hayes taking his own life.

The SWAT team showed up and broke down the door. Cops found Stephanie's body in the bathtub and Hayes was in the bedroom.

We're now told the LAPD wants to interview Floyd ... presumably because he was a witness to the murder-suicide.

Earl Hayes -- the man who cops say shot his famous wife to death Monday and then killed himself -- was haunted by her infidelity ... in particular what he said was a fling she had with singer Trey Songz.

As TMZ reported, Stephanie Moseley -- the star of VH1's "Hit the Floor" -- was gunned down in their L.A. apartment as neighbors heard her screaming. Shots rang out, the SWAT team came, busted through the door and discovered the 2 bodies.

Sources connected with Hayes tell us ... around 2 years ago he separated from Stephanie because of what he says was her affair with Songz. They got back together but, as one friend put it, "He was crushed and never got over it." We're told he frequently brought up Songz.

Hayes accused Moseley of having multiple affairs with various other entertainers. She was a backup dancer who worked with numerous famous singers, including Chris Brown and Usher, but we're told Hayes never mentioned them as a source of conflict.

Hayes and Moseley married in 2008 and his friends say he loved her and tried rationalizing staying together.

TMZ broke the story ... Floyd Mayweather was on FaceTime with Hayes when he flew into a rage over Moseley's alleged infidelity and the boxer was witness to the murder/suicide.

We reached out to Songz and got no word back, but Monday night he tweeted this.

Just hours after witnessing a murder/suicide via FaceTime, Floyd Mayweather decided to get out of his house to sit courtside at the L.A. Clippers basketball game Monday night.

Floyd actually appeared to be in a pretty decent mood considering the circumstances ... shaking hands and talking with Clippers stars Chris Paul and Jamal Crawford before they took on the Phoenix Suns at Staples Center.

As TMZ first reported, Floyd was on the phone Monday morning with rapper Earl Hayes when he killed his wife, VH1 star Stephanie Moseley, and then himself.

Floyd Mayweather is reeling tonight ... because he was on FaceTime with one of his best friends when the guy pulled out a gun, shot his wife and then killed himself ... TMZ has learned.

Sources tell us ... rapper Earl Hayes called Floyd on FaceTime Monday morning in a rage, over claims his wife -- VH1 star Stephanie Moseley -- had been unfaithful.

According to our Floyd sources, Earl said he was going to kill his wife. The champ was pleading with him to get a grip ... to no avail. Floyd will not say how much he saw, but he acknowledges he was a witness and heard everything.

Ken Weatherwax -- who played Pugsley on "The Addams Family" TV show -- died at his home Sunday in California after having a heart attack.

Weatherwax's family tells TMZ there will be 2 funerals -- one for the family, and one for his fans.

The actor stuck with the Pugsley role over the years ... long after the original TV show went off the air in 1966. He was the voice of Pugsley in a '70s version -- and played Pugsley Sr. in an 'Addams' TV movie.

He eventually started working behind the scenes as a grip and set builder -- but he still made appearances at fan conventions.

Weatherwax was 59 years old.

(snap snap)

2:30 PM PT -- We've learned Moseley and Hayes were married.

2:00 PM PT -- Law enforcement tells TMZ, Hayes shot Moseley and then turned the gun on himself.

"Hit the Floor" star Stephanie Moseley is dead .... after her rapper husband -- a member of Floyd Mayweather's Money Team -- shot her and then killed himself ... TMZ has learned.

We're told residents at a swanky L.A. apartment complex near The Grove heard shots ring out early Monday morning. The SWAT team raced to the scene and knocked down the door of an apartment ... and found 2 people shot to death.

The rapper Earl Hayes -- who was once signed to Mayweather's record label -- often partied with Floyd. Moseley has been a backup dancer with numerous singers, including Chris Brown and Britney Spears.

Residents heard a woman screaming in the apartment before shots rang out.

Sources connected with Moseley and Hayes tell TMZ ... he had accused her of infidelity with a famous singer.

Chris Brown just Instagrammed, "RIP baby girl. Danced with me on tour and was always the coolest person. My prayers go out to you and HAZE family."

Casey Kasem's life after death continues to be tumultuous ... American Express is gunning for more than $40K of the money he left behind.

Amex filed a creditor's claim, claiming Casey or someone in his world racked up $41,046.70.

The late DJ was in no position to use his card for more than a year before his death ... maybe more. Presumably his wife Jean used it for various purposes.

"Real Housewives of Atlanta" star Mama Joyce regrets her toxic relationship with her in-law Miss Sharon, but still ... she has no plans to go to the funeral.

Mama Joyce famously belittled her son-in-law Todd Tucker and his mom Sharon Tucker on the show ... claiming he was money hungry and Sharon was a prostitute.

But now Joyce tells TMZ she is sorry for attacking Sharon by repeating gossip (which turned out to be false) -- and wishes they'd patched things up before Miss Sharon died on Tuesday.

Silver lining? Kandi Burruss' mom says she wants to have a better relationship with Todd.

MJ added she won't attend the funeral out of respect for Miss Sharon's friends and family. She knows a lot of people would be pissed if she showed her face ... so instead she's going to send flowers.

Kandi Burruss' mother-in-law, Sharon Tucker, died in NYC Tuesday ... after suffering a stroke one day earlier.

Todd Tucker immediately flew from ATL to NY after getting the news about his mother's stroke ... according to sources close to Kandi and her husband. Todd's mom frequently appeared on "Real Housewives of Atlanta" ... and went by Miss Sharon on the show.

She slipped into a coma overnight while hospitalized after the stroke. We're told Kandi and Todd were by her side when Miss Sharon died.
