The FBI and U.S. Attorney’s Office for the District of Massachusetts have concluded their investigation into the horrific December mass shooting at Brown University and the subsequent murder of an MIT professor, revealing that the lone gunman started plotting the attack as early as 2022.

Claudio Manuel Neves Valente, 48, a Portuguese national who lived as a legal permanent resident in Miami, Florida, carried out the December 13 massacre in Providence, Rhode Island, before murdering MIT Professor Nuno Loureiro in Brookline, Massachusetts, two days later.

Two Brown students, Ella Cook, 19, and Muhammad Aziz Umurzokov, 18, were killed in the on-campus attack and nine other people were wounded.

Valente, a former Brown student, studied physics with Loureiro from the fall of 2000 through the spring of 2001 before withdrawing from the program by 2003. The FBI confirmed the shootings had no connection with terrorism.

According to the FBI’s Behavioral Analysis Unit, Valente viewed his victims as “symbolic” targets. Struggling with long-term suicidal ideations, paranoia and an ongoing “failure to thrive,” the unemployed former ride-hailingdriver had an “inflated sense of self” and blamed others for preventing him from reaching his full potential.

Valente, a former physics prodigy, used violence to overcome his shame and punish those he felt contributed to his downfall, investigators found.

The FBI said the attacks were meticulously planned over several years in isolation.

Valente began plotting the Brown University massacre as early as 2022, renting a storage unit in Salem, New Hampshire, to stash his weapons.

Officials said that because of his transient lifestyle and social isolation, Valente did not have family or peers to report warning signs to authorities.

Following the two shootings, Valente left behind a chilling series of audio and video files confessing to the murders, showing no signs of remorse and failing to explain why he committed the crimes.

In one file, he called his shooting victims “kind of stupid.” Valente added that he didn’t “give a d—” if he was judged for his actions.

Authorities recovered his body in Salem, New Hampshire, alongside two 9mm Glock pistols after he committed suicide.

The FBI noted both firearms, a Glock 34 used at Brown University and a Glock 26 used in the murder of Loureiro, were legally purchased by Valente from a Florida pawn shop in 2020 and 2022.

Officials said the multi-agency probe into Valente’s motivations involved scouring more than 11,000 surveillance files, analyzing over 2,100 audio and video files from his personal devices, and conducting upward of 260 interviews.

A public rift has emerged between Bryan Kohberger’s defense lawyers and a hired expert witness following his guilty plea in the murders of four University of Idaho students.

In their first public statement made outside the courtroom since Kohberger’s arrest in December 2022, Kohberger’s lawyers have accused a former defense expert, the criminologist Brent Turvey, of violating a confidentiality agreement by speaking about the case.

“Mr. Turvey has not been released from his confidentiality agreement, and is now speaking about topics that are still confidential, many of which are outside of his areas of expertise,” reads a statement signed by Kohberger attorneys Anne Taylor, Elisa Massoth and Bicka Barlow.

Turvey is a forensic scientist with a Ph.D. in criminology. In a fiery statement released Tuesday evening, Kohberger’s lawyers wrote they are “appalled” by his recent comments.

“It is the opinion of the defense team that Mr. Turvey’s conduct falls outside of the ethical and legal norms that are applied to experts in criminal cases, and his reliability should be seen through the lens of this conduct,” they wrote.

Turvey has spoken with a number of news outlets in recent days, including Fox News Digital, after breaking his silence in a newly released book about the case by former FBI agent Christopher Whitcomb, “Broken Plea,” which revealed a defense assertion that there were serious problems surrounding the chief piece of physical evidence in the case.

In those interviews, Turvey discussed evidence he reviewed for the defense and internal disagreements over testing and strategy — prompting the rare statement from Taylor, Massoth and Barlow.

However, he denied that he divulged any confidential information and alleged that Taylor’s office was under investigation in connection with the leak of confidential video before Kohberger’s guilty plea in violation of a restrictive gag order.

“Her press release comes as a bit of a surprise given that nothing confidential was revealed by me,” he told Fox News Digital.

In addition to denying having divulged any confidential material, he mentioned that Taylor’s office had been investigated in connection with a leak of investigative materials to Dateline last year. The prosecution team had also been investigated over the incident, and the court has not publicly identified the leaker.

“I know that the NBC evidence link was not me, and I’ve sworn an affidavit to that effect for the court’s administrative investigation which has been completed, but the results sealed,” Turvey said. “The most bizarre part of Anne Taylor’s press release is that she makes an allegation without being specific or providing any evidence. It’s not just false and unprofessional, it likely violates her own ethics as an attorney and the law if she is alleging a crime.”

He said the things he’s been speaking about have been “buried in mass public disclosures.”

The major revelation in “Broken Plea” stems from a purported chain of custody problem with Kohberger’s Ka-Bar knife sheath, which had his DNA under the snap. It was not mentioned in Turvey’s expert report, which he said was filed before he learned of it.

The evidence bag appears to have been filled in twice — once on the bag itself, and later on a sticker attached to the front.

The earliest date visible on the bag is “11/14/22,” alongside the initials “BP,” likely belonging to lead detective Brett Payne. It was written over the evidence tape sealing the bag.

BRYAN KOHBERGER’S DEFENSE TEAM OPPOSES DEATH PENALTY: ‘CRUEL AND UNUSUAL’

The label, affixed sometime later, has six recorded exchanges between Nov. 13 and Nov. 16 written with a single pen in similar handwriting, according to Turvey.

Turvey maintains that should have made it inadmissible.

Had Kohberger’s case gone to trial, prosecutors would have challenged his findings, which have not been evaluated by a judge or jury. Experts have downplayed the significance of his claims.

Paul Mauro, a retired NYPD inspector and Fox News contributor, reviewed images of the chain of custody forms and said he didn’t see a significant problem for the prosecution.

“What it could point to is that is a vulnerability in the case, so they take a plea,” he said. “They could have been concerned about losing a juror on that. On the other hand it’s very indicative of what you do when you have absolutely no defense, you put the procedure on trial, instead of the facts.”

Turvey said his rift with Taylor goes back to around the time of Kohberger’s plea deal. She had not pursued his chain of custody concerns or DNA testing he wanted for additional hair evidence.

“Until we had the first and only all team member meeting, the day after the plea agreement, we were in excellent terms and in a place of complete confidence and professional trust — as far as I was concerned,” he said. “Things took a dramatic turn during that meeting.”

He declined to discuss specifics, but said previously that the plea deal came as a surprise to him and despite his chain of custody concerns and a push to have additional DNA testing performed.

He took a plea deal that spared him from the potential death penalty. He forfeited his right to appeal. He gave no explanation for the crimes and sat emotionlessly through sentencing weeks later, as the victims’ families read scathing impact statements in court.

On the night of the murders, he searched Google for local police dispatch audio, according to public records tied to the case. He powered off his phone before the murders and turned it back on after them. While investigators found none of the victims’ DNA in his car after they seized it in Pennsylvania, an FBI analyst determined soil on a shovel found inside it matched dirt from the Moscow area.

“Truth be told, I’m unable to come up with anything redeeming about Mr. Kohberger,” Judge Steven Hippler said at sentencing. “His grotesque acts of evil have buried and hidden anything that might have been good or intrinsically human about him.”

Hippler handed down a sentence of four consecutive terms of life in prison with no parole, plus another 10 years.

A Mississippi man is charged with killing his mother after authorities allegedly found him trying to flush pieces of her flesh down a toilet in what a local sheriff called one of “the most heinous crimes that I’ve ever witnessed in my entire life.”

Zachary Lavel Jackson Jr., 29, faces charges of first-degree murder, second-degree murder, mayhem and tampering with evidence in connection with the death of his mother, Lana Brown Bradley, 62, a retired teacher.

The Adams County Sheriff’s Office said deputies initially responded April 4 to Bradley’s home in Natchez, after her relatives reported her missing.

Jackson was initially identified as a family member of Bradley before investigators confirmed he was her son.

“This is by far the most heinous crime that I’ve ever witnessed in my entire life. We weren’t out there that day; this was one of those things when we walked up. This was one of those cases that you will never, ever forget in your life. This is the type of case that follows you home,” Adams County Sheriff Travis Patten told WJTV.

Deputies were called to Bradley’s home after her oldest son could not reach her the previous day. Two of Bradley’s other sons lived with her.

“As soon as they walked in the house, they could just see where somebody had been cleaning up, and they could smell chemicals all throughout the house. Floor was extremely slippery. And the older son said that this is just unusual for the youngest son to be cleaning up the house like that,” Patten explained.

Jackson, the youngest son, was found in a bathroom where deputies allegedly saw a black substance in the toilet.

“I can say what was in the toilet, and it was her flesh. He chopped her up in pieces and dismembered her in a way that whoever came looking for her would have to do their due diligence to find her, and that’s just what we did,” the sheriff said.

Authorities stated that Jackson had allegedly placed his mother’s body parts in a suitcase and flushed the rest down the toilet after dismembering her. Bradley had threatened to evict her son from the home, according to the sheriff, who cited interviews with family members stating that Jackson was mentally unstable.

However, Patten noted that Jackson was “very calculating” when he allegedly committed the crime.

“He had threatened her the day before because she was looking to have him evicted from the home. She was in the process of doing so and had just gone to court the day before to have him removed from the home,” Patten explained.

The wreckage of the U.S. Coast Guard cutter “Tampa,” which sank in World War I during the largest single American naval combat loss of the conflict, was recently discovered at the bottom of the Atlantic Ocean after more than a century.

A British technical-diving team called “Gasperados” found the historic vessel roughly 50 miles off the coast of Newquay, Cornwall, in the United Kingdom, resting at a depth of more than 300 feet.

The volunteer dive team spent three years searching for the wreckage, eventually confirming its identity with the help of the Coast Guard Historians Office, which provided historical records, technical data and archival images of the ship’s wheel, bell, deck fittings and weaponry.

The Tampa was lost on Sept. 26, 1918, just weeks before the end of World War I, when it was struck by a torpedo from the German submarine UB-91 in the Bristol Channel.

LONG-LOST WARSHIP DESTROYED BY ICONIC NAVAL COMMANDER DISCOVERED CENTURIES LATER: ‘QUITE REMARKABLE’

The devastating blast caused the ship to sink in under three minutes, leaving no chance for survival.

All 131 people on board were killed, including 111 Coast Guardsmen, four U.S. Navy personnel, and 16 British Navy personnel and civilians.

“Since 1790, the Coast Guard has defended our nation during every armed conflict in American history, a legacy reflected in the courage and sacrifice of the crew of Coast Guard Cutter Tampa,” Coast Guard Commandant Adm. Kevin Lunday wrote in a statement. “When the Tampa was lost with all hands in 1918, it left an enduring grief in our service. Locating the wreck connects us to their sacrifice and reminds us that devotion to duty endures. We will always remember them.  We are proud to carry their spirit forward in defense of the United States.”

The doomed crew came from all walks of life to serve their country, according to the Coast Guard.

In 1999, 81 years after the tragic sinking, the crew members of the Tampa were posthumously awarded the Purple Heart.

This group included 11 Black sailors who became the first uniformed minority Coast Guardsmen to die in combat and receive the Purple Heart.

The Coast Guard is developing plans for underwater research and exploration of the Tampa site, coordinating with historians, robotics and autonomous systems and specialized dive teams.

A repeat sex offender with a decades-long history of violations is back in custody after a terrifying middle-of-the-night encounter with a child in Omaha, Nebraska.

Lavern Scott, 65, known by authorities as “Cookie Monster,” has been on the sex offender registry since 1987.

Police say early Friday morning, that didn’t stop him.

Officers were called to an apartment near 13th and Leavenworth around 1 a.m. after reports of a naked intruder, according to court documents obtained by WOWT. Investigators said that Scott walked through an unlocked front door, stripped off his clothes and went straight into a sleeping child’s bedroom.

A 9-year-old woke up to a nightmare.

“The suspect then got into bed,” police wrote.

Moments later, the child began screaming.

Authorities say Scott pinned the child down, locking his legs in and using his feet “as hooks” to hold the child in place.

A family member rushed in and found Scott at the foot of the bed with a bottle of water and lotion, forcing him out before the situation escalated even further.

But the chaos didn’t end there.

Just one block away, police say Scott entered a second home, an Airbnb, claiming it was his. Residents removed him before officers later found him wandering a nearby street corner, wearing nothing but socks.

For law enforcement, this case is about more than one terrifying night, it’s about a pattern.

Scott’s criminal history spans decades. In addition to his 1987 conviction involving a minor, he was convicted in 1999 of attempted first-degree sexual assault. He has also been cited multiple times for indecent exposure and trespassing.

FAMILY WARNED NONPROFIT NOT TO FREE REPEAT OFFENDER WHO ALLEGEDLY KILLED MAN DAYS LATER

And despite being required to register for life, Scott has repeatedly failed to comply.

Records show violations in 2017, 2018, 2022 and 2024—totaling 2,777 days out of compliance. His last known registration with authorities was in 2023.

In Douglas County, there are 1,681 registered sex offenders. Authorities say 233 are currently non-compliant — living in the community with little to no supervision.

Scott was one of them.

“He’s the classic definition of a repeat offender, of a predator,” Sheriff Aaron Hanson said.

Hanson is now sounding the alarm, acknowledging that “the system failed” and is calling for stronger supervision and coordination before another child becomes a victim.

GOT A TIP?

Despite round-the-clock efforts by law enforcement, he said current state laws offer very few real tools to monitor high-risk offenders—leaving dangerous gaps before something like this happens.

The Omaha Police Association echoed those concerns, pointing to hundreds of non-compliant offenders still in the community and the risks they pose.

“This is why repeat offenders must be taken seriously,” the organization wrote in a post on its Facebook page.

Officials say tips from the public are critical in tracking offenders. Anyone with information is urged to call the tip line at 402-444-6000.
