True Crime

John Bennett Ramsey has plans to meet with local police once again ... in hopes of convincing them to use new DNA-testing technology to solve his daughter's killing.

The father of JonBenét is expected to speak with the Boulder Police Department in Colorado again in January, along with representatives from a leading DNA lab, to push for a new approach to evidence authorities collected nearly three decades ago.

John explains there is new DNA tech that could separate mixed samples ... a major issue with DNA collected at the time, he says. Ramsey's hopeful the police will allow an independent lab to conduct testing on the old crime scene items. JonBenét was killed on Christmas night in 1996, and her body was found hours later, after she had been reported missing.

Suspected Idaho murderer Bryan Kohberger could have had more practice than anyone thought before he allegedly killed 4 University of Idaho students ... turns out he was under investigation for a home invasion that had many of the markings of the savage murders.

The home invasion went down in Pullman, Washington in late 2021, a little more than a year before the Univ. of Idaho murders in a town just a few miles away.

A woman in the house told cops, "I heard my door open and I looked over, and someone was wearing a ski mask and had a knife."

Luigi Mangione's attorney is calling out NYC Mayor Eric Adams for putting on a dog and pony show with the alleged murderer that will make it impossible for her client to get a fair trial.

Karen Friedman Agnifilo went off on Mayor Adams and law enforcement Monday during Mangione's arraignment, blasting him for last week's scene on a helicopter pad as Mangione was extradited to face murder charges. You'll recall he was flanked by about a dozen NYPD officers and FBI agents -- many heavily armed -- as well as the Mayor himself.

Agnifilo says her client's Constitutional right to a presumption of innocence is being violated -- he was on display for everyone to see in the biggest staged perp walk I've ever seen in my career" ... none of which was necessary, she says, as Mangione's been totally cooperative since his arrest in PA.

Luigi Mangione says he's not guilty of slaying UnitedHealthcare CEO Brian Thompson -- he entered not guilty pleas Monday morning in New York State court.

Mangione pleaded not guilty to 11 state charges ... including first-degree murder, second-degree murder as crime of terrorism and multiple weapons charges.

The 26-year-old Ivy League grad was dressed like a college preppie -- a maroon sweater over a white collared shirt and khaki pants -- as he stood before the judge with his attorney Karen Friedman Agnifilo.

Luigi Mangione's got hundreds of people donating money to his defense fund ... and a spokesperson for one committee is explaining why they're trying to help him pay his legal fees.

Jamie Peck -- a member of The December 4th Legal Committee -- tells TMZ … part of the reason why they started the fund for Mangione is their belief everyone deserves a fair trial – even someone accused of terrorism.

While Peck makes it clear she isn't co-signing the violence, she hopes the case will have people talking about the broken healthcare system in America.

A TikTok account that potentially belonged to the Wisconsin school shooter is now deleted on the heels of complaints about racist comments on the page ... TMZ has learned.

The account possibly belonging to 15-year-old Natalie Rupnow was first highlighted by the Anti-Defamation League's Center on Extremism -- and when we checked it out, we found it only had 2 posts, both related to the movie "Fight Club" ... but they were flooded with comments that were clearly left after the tragedy in Madison, WI.

We confirmed with the ADL the username its people observed was @targetedbloodsport -- and according to them, the account featured the phrase, "Totally nice day," similar to "Totally normal day" ... which the ADL claims is used by racists or white supremacists.

Luigi Mangione's leaving his orange jumpsuit at the courthouse door ... ditching the prison garb for a more fashionable ensemble in federal court Thursday.

According to reports, Mangione entered the Manhattan courtroom wearing "a white button-down shirt, navy three-quarter zip pullover and khaki pants."

Mangione wasn't handcuffed during his court appearance ... though, according to CNN, when court ended for the day Mangione was led from the room between two marshals with his ankles shackled.

An ex-neighbor of the California man accused of plotting a local mass shooting in a coordinated attack with the Wisconsin school shooter is speaking out ... telling TMZ about the chilling, ominous energy he always carried.

The woman, choosing to remain anonymous, talked to us on "TMZ Live" Thursday, revealing that during the 5 to 6 years she lived near 20-year-old Alexander Paffendorf, he exhibited seriously creepy behavior -- never talking, avoiding eye contact, always wearing his hood up, and other unsettling anti-social habits.

Catch the video, because she dives into the specific moments when Paffendorf made her feel super uncomfortable around their apartment complex -- and it’s spine-chilling.

Luigi Mangione planned the murder of UnitedHealthcare CEO Brian Thompson months in advance ... and, he'd clearly been thinking about it longer -- so say federal prosecutors.

In the federal criminal complaint -- filed Thursday -- prosecutors included several diary entries they claim Mangione made over the past few months ... all of which seem to point to Mangione as Thompson's killer.

An entry dated August 15 describes how he's "glad -- in a way -- that I've procrastinated" because it allowed him to learn more about a "Company-1" ... which is how the feds refer to UnitedHealthcare throughout the docs.

Luigi Mangione has arrived in New York to face state and federal charges after being extradited from Pennsylvania.

The suspected killer in the murder of UnitedHealthcare CEO Brian Thompson was spotted arriving in New York City Thursday, just hours after appearing in a Pennsylvania court where he formally waived extradition.

Luigi, sporting his fresh shave and new haircut, looked somber as he was led into a secure police vehicle. NYC Mayor Eric Adams was among the dozens of law enforcement personnel who escorted Mangione from a helicopter to the awaiting vehicle.

Luigi Mangione is on the move ... the suspected killer in the murder of UnitedHealthcare CEO Brian Thompson is being extradited from Pennsylvania to New York.

Luigi appeared in court Thursday in Pennsylvania and waived extradition ... and now he's being transported back to the scene of his alleged crime.

Mangione is accused of fatally shooting Thompson earlier this month outside a hotel in Manhattan ... and five days after the shooting he was arrested at a McDonald's in Altoona, PA.

Luigi Mangione was back in court Thursday morning for another extradition hearing ... and his admirers lost their minds 'cause he's cleaned up with a shave and a haircut.

Here's the deal ... Mangione formally waived extradition after he arrived at a Pennsylvania courthouse under heavy security -- he's been officially charged in NYC with the murder of UnitedHealthcare CEO Brian Thompson.

Video captured Mangione being led into the courthouse -- and he appeared to be more subdued than last time, when he lashed out at cameras shortly after he was apprehended.

7:07 AM PT -- Luigi Mangione formally waived extradition moments ago. He is expected to be taken from Pennsylvania to New York immediately.

Luigi Mangione arrived at a Pennsylvania court under heavy security Thursday morning for his extradition hearing -- and video briefly captured the Ivy League grad surrounded by police.

Check it out ... An Altoona, PA, police car initially drives past a scrum of photogs outside the courthouse and parks inside an open garage.

Police officers then help Mangione -- wearing an orange jumpsuit with hands cuffed behind him -- out of the backseat, escorting him inside the building. From the camera's vantage point, you can only catch a glimpse of the serious look on Luigi's face.

Luigi Mangione -- the suspected murderer of UnitedHealthcare CEO Brian Thompson -- has more headaches to contend with because he's reportedly facing federal charges.

According to the New York Times, Mangione was hit with the federal criminal case from prosecutors in the Southern District of New York in connection with the fatal shooting of Thompson in Manhattan on December 4.

As we reported ... Mangione had already been indicted on 3 state murder charges and other serious crimes brought by prosecutors in the Manhattan D.A.'s Office. Manhattan D.A. Alvin Bragg says 2 of the murder counts are considered acts of terrorism.

The NYT says as of now the federal charges are unclear ... but once a possible indictment is unsealed, SDNY prosecutors could pursue the death penalty, which was abolished in New York state in 2007, yet it remains on the books on the federal level.

Mangione’s attorney, Karen Friedman Agnifilo, issued a statement. “The federal government’s reported decision to pile on top of an already overcharged first-degree murder and state terror case is highly unusual and raises serious constitutional and statutory double jeopardy concerns,” the statement said. “We are ready to fight these charges in whatever court they are brought.”

Mangione will appear in a Pennsylvania courtroom Thursday morning for a hearing in which he's expected to waive extradition to NYC to face the state charges.

Luigi Mangione mentioned the big bucks he had in the bank on a trip to Thailand ... and also, repeatedly brought up a couple of revealing books -- TMZ has learned.

A source -- who doesn't want to be identified by name, but who spent significant time with Luigi back in April -- tells TMZ ... the two went to the popular tourism destination together, hitting up bars and visiting a weed shop, and cracking inside jokes over a period of two days.

According to his friend, Luigi was "making lawyer money" coding for TrueCar ... a telling statement because Mangione reportedly stopped working for them months before going to Thailand.

3:27 PM PT -- Nima Momeni's attorney Bradford Cohen tells TMZ … Momeni will be appealing, and "We believe there is enough error during the trial to afford him a good chance at a retrial."

Cohen asserts the state's attorney had to "overcharge the defendant" due to rampant crime in San Francisco, saying ... "It's disappointing that after seeing a video in which it proved that the state's witness, Bo Mohazzabi, was a liar, and additionally showed what appears to be Bob Lee holding a knife and snorting a substance off of it, that they came back with 2nd-degree murder."

San Francisco jurors found the man accused of killing the founder of Cash App guilty of murder Tuesday ... following a 6-week trial featuring conflicting testimony about drugs and revenge.

Nima Momeni was found guilty of second-degree murder after the jury deliberated for 7 days. The jury reached the verdict Monday night, but it was not read in court until this morning.

The founder of Cash App, 43-year-old Bob Lee, was stabbed to death in April 2023 under the Bay Bridge in San Francisco. He was stabbed 3 times, including through his heart, with a paring knife ... and he managed to call 911 before he died later in a hospital.
