RIP

Rodeo star Spencer Wright's three-year-old son tragically passed away on Sunday ... two weeks after he was left in critical condition following a toy tractor accident.

A friend of the Wright family confirmed the heartbreaking news to People ... saying they had to make the impossible decision to let Levi go.

Jayla Allen -- the daughter of Dallas Cowboys legend Larry Allen -- said in a social media post Monday night she's stunned over her dad's death ... writing in an emotional message, "I feel like this is a nightmare and I can't [wake] up."

Larry -- a Pro Football Hall of Famer and one of the greatest interior offensive linemen the NFL's ever seen -- died on Sunday while on vacation in Mexico ... and his daughter seemed to indicate he had shown no signs of being in poor health prior to the tragedy.

Jayla said Larry's death left her "in complete shock," and now, she's not quite sure how she's going to pick up the pieces he left behind.

The rapper passed away Monday -- this according to the group's official social media accounts ... which noted he "went to the upper room." 2LC's manager confirmed his death to us, but didn't have any further details on the cause or manner.

Emmitt Smith was devastated to learn of the passing of his former teammate Larry Allen on Monday ... saying in an emotional video he's at "a loss for words right now."

Smith, through tears, remembered Allen as a "good dude," a "great player," and a "super person" in a clip he posted to his Instagram page just minutes after the Dallas Cowboys revealed the former offensive lineman had died Sunday while on vacation in Mexico.

Smith played with Allen from 1994 to 2002 ... and while he said he hadn't been able to see much of the Hall of Famer following his retirement, he was still obviously shaken.

Jay Leno is railing against the light punishment for most perps caught stealing catalytic converters as the L.A. crime wave is turning deadly ... specifically with the recent murder of "General Hospital" actor Johnny Wactor.

The stand-up comic and renowned car guru tells TMZ ... it's outrageous the penalty for ripping off converters -- usually a $1,000 fine amounting to just a misdemeanor charge -- isn’t vastly harsher.

JL adds ... The slap on the wrist most thieves receive -- if they even get nabbed -- is the reason they're so brazen.

"Crocodile Hunter" Steve Irwin may've died almost 2 decades ago ... but his widow Terri has no interest in dating.

The conservationist made this point very clear during the annual Steve Irwin Gala, telling Us Weekly she isn't dating at the moment ... nor does she plan to in the future.

She added ... "I totally got my happily ever after. And while there are a lot of wonderful men in the world, can you see another Steve Irwin? I just can’t. I’d be like, ‘I love that you’re a librarian and the Dewey Decimal System is cool, but I got to go jump a crocodile and do that.’ Forget that."

"General Hospital" actor Johnny Wactor's employer is addressing his death -- and the internal outrage over alleged safety concerns  ... meanwhile, we got a big update on the criminal case itself.

Level 8 -- the bar where Johnny worked in downtown Los Angeles before he was shot and killed this weekend following a shift -- posted to Instagram Friday ... remembering him as a beloved coworker and cherished team member who was lost to a senseless act of violence.

Right after this tribute, though, Level 8 went on to tackle a growing chorus of employees and associates who've been blasting them over Johnny's death -- with claims that the bar hadn't done enough to protect their workers -- and they say they're going to delve into this issue.

The woman who was with Johnny Wactor the night he died just went on camera to describe exactly how his murder went down -- and it sounds tragic ... not to mention dramatic.

The band -- which consists of John Mayer and Bob Weir, plus other former Grateful Dead members -- projected images of Walton behind them throughout their hourslong concert at the must-see attraction in Las Vegas.

Some of the pics displayed on the building's massive screens included Walton with Weir and Mickey Hart. They also featured the former Celtics center's No. 32 jersey number, rose petals ... and a whole bunch of tie-dye colors.

10:56 AM PT -- Officials say Drew Gordon was driving a three-wheel Vanderhall Carmel when he crashed with a GMC Sierra pickup around 1 PM on Thursday.

Gordon died at the scene, while the 25-year-old driver of the GMC and a passenger were taken to a local hospital with non-life-threatening injuries.

Officials say the preliminary investigation indicates Gordon's vehicle crossed the center line and made contact with the GMC ... and impairment does not appear to have played a role in the accident.

Former NBA player Drew Gordon -- the brother of Denver Nuggets star Aaron Gordon -- died in a car accident in Portland on Thursday. He was just 33 years old.

Gordon was a star athlete growing up in California ... earning All-American honors at Archbishop Mitty High School in San Jose.

The two women opened up about their last words with Nicole for the new Lifetime documentary, "The Life and Murder of Nicole Brown Simpson" ... revealing she was focused on helping Faye get sober rather than her own problems in 1994.

The way Faye tells it, she relapsed just two days before Nicole and her friend Ron Goldman were killed ... and, it was actually NBS who worked on putting Resnick into rehab.

William H. Macy's taking a strong stance against violence -- in movies and television, that is ... claiming it's negatively impacting the entire world, and being pretty dang earnest too.

The actor discussed his feelings about violent cinema during his appearance on fellow actor Brett Goldstein's "Films To Be Buried With" podcast ... saying he thinks the senseless violence in film cheapens each death and downplays human life in general.

Macy says, "I swear to God, you kill one person, there's nothing more dramatic than that. You kill 18 people, it's just porn. The only thing you can do to make that more dramatic is kill 18 more."

A mayoral candidate in Mexico was assassinated at point-blank range -- and the murderous act was caught on camera ... with the killer himself being gunned down too.

The perpetrator isn't fully visible in the clip ... but you can see a gun in their hand, boldly pointed at the back of Cabrera's head just as he's about to address 300 supporters -- and then they fire.

A golfer at the U.S. Women's Open hit a birdie on Thursday ... but not one she was hoping for -- 'cause a winged creature is now dead after it got absolutely rocked by a ball.

The sad moment went down on the 12th hole at Lancaster Country Club ... when cameras captured the participant's approach shot.

As the ball came down from the sky, a bird was just chilling on the green ... and unfortunately, it was the worst case of being at the wrong place at the wrong time.
