RIP

Tom Petty is gracing a building that was his musical home for many years.

The folks at Warner Bros. Records just rolled out a larger than life mural of the singer, who passed Monday night.

Tom takes the place of Chester Bennington, who was also an artist with the label. As you know, Chester took his own life back in July.

The mural is in a strategic location in Burbank. Singers, actors and actresses traverse the street on their way to various record companies and studios.

The Las Vegas shooter apparently turned one of his rifles into a fully automatic weapon with an inexpensive modification that can easily be bought online.

It appears Stephen Paddock -- the man who brutally murdered 59 people and injured over 500 -- attached what's called a slide fire stock or bump stock to one of his 23 guns before spraying hundreds, if not thousands, of bullets into a crowd of concertgoers from his 32nd floor Mandalay Bay hotel room.

The stock allows the shooter to hold the trigger once and fire in rapid fashion at hundreds of rounds per minute, essentially making it a fully automatic rifle or something extremely close to it.

Automatic weapons are nearly impossible to obtain but a stock runs about $160 online, and it's legal.

It appears Paddock also had a SureFire 100 magazine hooked on the rifle with the stock. The 64-year-old reportedly had multiple high-capacity magazines loaded.

Sunday's shooting is the deadliest in modern U.S. history.

Hugh Hefner ultimately died of cardiac arrest, but

reveals he was also battling a few other ailments.

According to the doc, Hef was suffering from septicemia -- a severe inflammation of body tissues triggered by an infection in the blood. He'd also been dealing with E. coli ... and both are listed as contributing factors.

The main cause of death is listed as cardiac arrest.

As we reported, Hefner died last week at the Playboy Mansion ... surrounded by loved ones at 91.

Tom Petty died Monday night ... his longtime manager, Tony Dimitriades, confirms.

We broke the story -- EMTs responded to a call at Tom's home Sunday night for a person who was unconscious, not breathing and in full cardiac arrest -- he was taken to UCLA Santa Monica Hospital, where he was immediately put on life support.

Dimitriades says Petty died at 8:40 PM PT at UCLA surrounded by friends, family and his bandmates.

After learning Tom had no brain activity, his family chose to take him off life support.

Tom hit it big in 1978 with his band, the Heartbreakers ... which scored hits with "Don't Do Me Like That" and "Here Comes My Girl" to name just a few.

Tom also wrote and recorded "Stop Draggin' My Heart Around" with Stevie Nicks in 1981.

Later in the '80s he recorded with The Traveling Wilburys -- a legendary lineup comprised of Bob Dylan, George Harrison, Roy Orbison and Jeff Lynne -- and made a big hit, "Handle with Care."

And Tom recorded solo and had the smash hit, "Free Fallin'."

He was inducted into the Rock & Roll Hall of Fame in 2002, and has remained a huge touring draw. He just wrapped up his 40th anniversary tour last week at the Hollywood Bowl.

He was 66.

RIP

Coldplay paid tribute to Tom Petty during their Monday concert in Portland, Oregon as the rock legend was taking his final breaths.

Chris Martin and co. covered Petty's epic "Free Fallin'" with R.E.M. guitarist Peter Buck at the Moda Center. They also opened the gig with a moment of silence for the Las Vegas mass shooting victims.

The group does a good job, although Martin can't match Petty's high notes.

TMZ broke the story ... Tom suffered a fatal cardiac arrest Sunday night and died later in the hospital. He was 66.

Al Pacino, Jack Nicholson and a bunch of other huge celebs were all under one roof to honor the late Harry Dean Stanton.

The flock of stars hit up No Name in L.A. Monday night to pay tribute. Warren Beatty, Elliot Mintz, John Savage, Henry Buck and Anjelica Huston were all there too.

Check it out ... Mintz gave his take on what made Harry so great while Pacino and Anjelica shared some thoughts on the horrific Vegas tragedy.

Tom Petty's tragic death has left Hollywood shocked, saddened but also thankful for his tunes and influence ... and plenty of stars are honoring the rock and roll legend, including fellow legend Paul McCartney.

Musicians and other celebs alike flocked to social media Monday to pay tribute and offer words of condolences after TMZ broke the story that Tom had gone into full cardiac arrest and was taken off life support.

As you might imagine, many fellow rockers spoke on his passing ... including John Mayer and Peter Frampton.

We lost another Goodfella -- Chuck Low, who famously played Morrie Kessler died at the age of 89.

Low was a close friend of Robert De Niro -- he was actually his landlord when he first got into acting ... eventually co-starring with him in "Goodfellas."

He reportedly died at a nursing home in New Jersey on Sept. 18 and, having served 30 years in the service ... got full military honors.

Low's most memorable role came as Morrie of Morrie's Wigs fame. His pal De Niro actually got to whack him. He went on to land roles in "The Sopranos," "Scent of a Woman" and "The Mission."

You'll recall Frank Vincent, who also starred in "Goodfellas" and 'Sopranos,' died the week before Low.

Mike Tyson, Kid Rock, The Chainsmokers ... just some of the big names digging into their pockets to help the victims of the horrific Las Vegas shooting.

After the Oakland Raiders donated $50,000 to the Las Vegas Victims' Fund -- a GoFundMe page set up by Clark County Commission Chair Steve Sisolak -- several huge stars kicked in with $10,000 donations including Florida Georgia Line.

Shelley Adelson, daughter of casino mogul Sheldon Adelson, also kicked in $10k.

We've also confirmed L.A. Rams pro bowl tackle Andrew Whitworth ponied up $25,000 to the fund.

Hoda Kotb has also added $1,000.

According to the GoFundMe page, the money raised "will be used to provide relief and financial support to the victims and families of the horrific Las Vegas mass shooting​."

Tom Petty's wife made a desperate 911 call and told the dispatcher she needed help because her husband wasn't breathing.

Dana York seemed confused and upset when she dialed 911 Sunday night at around 10:45 PM. The dispatcher tried to get her to administer CPR, but Dana needed help. You hear another man take the phone but then Dana takes it back.

She hears very soft breathing, tries CPR and it seems he breathes better.

TMZ broke the story, Tom was in full cardiac arrest and unconscious. He was taken to the hospital and put on life support but there was no brain activity. A chaplain came to administer last rights and he was taken off of life support.

He's not expected to survive the day.

Tilman Fertitta -- the man who just bought the Houston Rockets -- is working with the Vegas casino he owns to help victims and first responders affected by the mass shooting, TMZ Sports has learned.

Fertitta owns the Golden Nugget -- and we're told he's personally been on the phone with hotel management to help strategize how they can best use their resources to help out.

We're told the Nugget has already reached out to MGM Resorts to help house families of people killed or injured in the shootings. With more than 500 people injured, lodging could be an issue and Fertitta wants to make sure the families are taken care of.

Stephen Paddock's brother Eric Paddock seemed dumbfounded by the monstrous actions of his sibling.

Eric just appeared on CBS News and said his brother was not an avid gun collector. He had no idea where Stephen Paddock got automatic weapons ... no idea at all.

Eric was in the dark, because cops have already searched Stephen Paddock's home and it appears they found a cache of weapons and ammo. The recently-built house was well kept in the upscale retirement community.

Eric painted his brother as a normal guy living in Nevada ... eating burritos and gambling.

He was also relieved his brother didn't harm his girlfriend. He actually seems unsure whether she was his girlfriend or whether they were secretly married.

President Trump just addressed the nation on television for the first time since the mass shooting in Vegas.

In a response from The White House, Trump praised first responders and expressed his sympathy for the victims, their families and those injured during the attack.

Trump offered his "warmest condolences and sympathies" early Monday morning on Twitter after 64-year-old Stephen Paddock opened fire to a crowd of more than 20,000 concertgoers from the 32nd floor of the Mandalay Bay resort. At least 58 are dead and more than 500 people were rushed to hospitals.

Jason Aldean was in the middle of a performance late Sunday night when bullets rained down. Paddock, who cops say had more than 10 rifles in his room, shot and killed himself.

Trump called the LVMPD to thank them for their efforts.

Dan Bilzerian was recording on his cell phone as bullets rained down while fleeing the Route 91 Festival in Vegas, and he witnessed a horrific scene ... a woman getting shot in the head.

Dan posted this video Sunday night as concertgoers at the Mandalay Bay Resort ran for cover when 64-year-old Stephen Paddock started shooting. At least 50 are dead, more than 400 people were transported to hospitals.

Las Vegas police say Paddock killed himself in his room before SWAT team entered his room.

The frantic police audio during the Vegas massacre underscores the terror at the venue as bullets rained down into the crowd.

You hear law enforcement in the audio frantically screaming as they determined the shots are coming from an upstairs room at the Mandalay Bay resort. Some scream about multiple people being hit.

And then there's this ... a warning to police to lock their police cars because people in the area are trying to take their rifles that are inside the vehicles.

Hugh Hefner went to his final resting place Saturday, but only a select few of his closest friends and family were on hand for the ceremony ... TMZ has learned.

Our Playboy sources tell us ... Hef's 4 children, his wife Crystal Harris and some key Playboy staffers attended the funeral at L.A.'s Westwood Village Memorial Park Saturday at noon.

As we reported ... Hefner's crypt is directly to the left of Marilyn Monroe's -- he bought the burial spot for $75k in 1992. He'll have plenty of good company ... the cemetery is filled with celebs, many with Playboy ties.

One of the people buried in the cemetery -- around 100 feet from Hef's crypt -- is Dorothy Stratten, a Playboy Playmate who was murdered in 1980 by her estranged husband when she was just 20 years old. Her boyfriend at the time of her death, famed director Peter Bogdanovich, railed against Hefner, blaming him and the "Playboy sex factory" for her demise.
