Teenager faces murder charge in deadly Henderson marijuana robbery
John Mancuso is accused of killing Treyvon Jackson on July 22 at an apartment complex near Warm Springs Road and Green Valley Parkway. Jackson died from a gunshot wound to his torso, the coroner's office ruled.
A witness first told police she and Jackson arrived at the complex to buy an electric bike, documents said. She told police that during the sale, a man wearing a ski mask jumped out from behind a car and shot Jackson.
Through subsequent investigation, police determined the sale actually involved marijuana and possibly trading marijuana for a bike, documents said.
'[The witness] knew that [Jackson] had made an agreement to sell the marijuana for $700, but she did not know if they were going to trade for the bike or if Treyvon would be receiving cash for the purchase,' police said. 'Treyvon had the marijuana stored inside [a] backpack, which, when located at the crime scene, was empty and there was no marijuana inside.'
The witness later identified Jackson as a man she and Jackson met in the parking lot for the marijuana sale before the shooting, documents said.
The FBI Criminal Apprehension Team arrested Mancuso on July 28, records said. In addition to open murder with a deadly weapon, Mancuso faces charges of robbery with a deadly weapon and conspiracy to commit robbery.
It was not immediately clear if police suspected there were outstanding individuals connected to the case. At the time of the release of their investigation press release, Henderson police said 'no suspects' were identified. Police did not issue a follow-up press release for Mancuso's arrest.
Mancuso remained detained without bail at the Clark County Detention Center as of Monday. A preliminary hearing was scheduled for Tuesday.
The shooting marked Henderson's fourth homicide for 2025.

Colorado's Staunton State Park reopens after stabbing investigation
Staunton State Park reopened to the public on Wednesday morning after a Colorado Parks and Wildlife ranger was stabbed on Tuesday. The park was evacuated and closed to visitors during the investigation. The massive search for the man who allegedly stabbed a seasonal park ranger at the park in Jefferson County was suspended Tuesday evening after eight hours. Investigators said they had reason to believe it had been a targeted attack and there was no ongoing threat to the community. The seasonal park ranger was stabbed in the torso in a conflict with a man at about 9:30 a.m. Tuesday in the area of the Staunton Rocks. He was rushed to the hospital with serious injuries and the Jeffco sheriff's spokesperson said the ranger was doing "pretty well." Schools and residents in the area were locked down as law enforcement from multiple agencies searched for the suspect. The park reopened to visitors on Wednesday morning. There have been no arrests in connection with the stabbing.

Vance says National Guard is 'busting their a--' in Washington, floats mission extension
Vice President JD Vance touted the progress National Guard troops have made tackling crime in Washington the past nine days — and suggested that their mission may extend past 30 days. President Donald Trump unveiled plans Aug. 11 to deploy troops from the D.C. National Guard and to federalize the Metropolitan Police Department to tackle crime in Washington. And, so far, those efforts are paying off, according to Vance. "We are seeing really substantial effects because these guys are busting their a--," Vance said while meeting with National Guard troops at Washington's Union Station Wednesday. "Right here in Union Station, you have vagrants, you have drug addicts, you have the chronically homeless, you have the mentally ill who harass, who threatened violence, who attacked families," Vance said. "And they've done it for far too long. This should be a monument to American greatness." The 1973 Home Rule Act permits a temporary federal takeover of the Metropolitan Police Department for emergency situations up to 30 days. However, after that time frame, Congress must intervene and sign off on any extensions. No such limitations exist for D.C. National Guard troops, however, in the Home Rule Act. On Aug. 13, Trump said that the administration's goal was to ramp down crime quickly, but signaled that "we're going to want extensions." When asked if extensions were on the table, Vance said that Trump would reevaluate, depending on how much progress occurs in the next several weeks. "We'll ultimately let the president of the United States determine where we are after 30 days of this, of this emergency order. I think that we're going to make a lot of progress over the next 20 days," Vance said. "I think we're nine days into this thing. But if the president of the United States thinks that he has to extend his order to ensure that people have access to public safety, then that's exactly what he'll do. If he thinks he doesn't have to do that, obviously we'll make that determination." Meanwhile, Washington officials filed a lawsuit challenging the Trump administration's move to federalize local police Friday. "By illegally declaring a takeover of MPD, the Administration is abusing its temporary, limited authority under the law," Washington, D.C., Attorney General Brian Schwalb wrote in a Friday X post. "This is the gravest threat to Home Rule DC has ever faced, and we are fighting to stop it." In addition to the DC National Guard, National Guard troops from Ohio, West Virginia, South Carolina, Louisiana, Mississippi and Tennessee are participating in the Trump administration's crackdown in Washington, and approximately 1,300 have already arrived in the nation's capital.

Amanda Knox: How one misunderstood text sparked suspicion in infamous murder case
Fox Nation is revisiting one of the most sensational true crime cases of the 21st century – the Amanda Knox story – in a new special that reexamines the twists, trials and lingering questions surrounding the American exchange student accused of murder in Italy. The Seattle native spent nearly four years in an Italian prison after being accused of murdering her roommate Meredith Kercher while studying abroad. To some, she was a cold-blooded killer. To others, she was a scapegoat trapped in a legal nightmare. "Since O.J. Simpson, this was the biggest case. This was the other case of the century, and it was going to be spun by different people [in] different ways," said Dr. Greg Hampikian, a forensic DNA expert, in the new special. Along with attorney Anne Bremner and journalist Angenette Levy, Hampikian broke down the Knox case in the Fox Nation special, starting from the moment she left the U.S. and became a suspect abroad. Before the handcuffs, Knox was a student at the University of Washington with her sights set on Europe. "She wanted to go abroad like anybody at that age, wanting to branch out," said Bremner. She worked three jobs, including one as a barista, to make that dream a reality. With a goal to learn Italian and become a translator, she arrived in Perugia, Italy in September 2007 and moved into a flat with three roommates, one of whom was Kercher, a British exchange student. Along the way, a romantic relationship emerged when Knox met a man while attending a concert with Kercher. Raffaele Sollecito, a 23-year-old student who was in the area to study information technology, was added to the triangle of suspicion surrounding Kercher's unexpected death. There were reports that Kercher was stabbed several times and sexually assaulted in the middle of the night, but further details surrounding the incident remained mysterious. With a window broken and a rock found nearby, police initially speculated that the crime was a burglary gone wrong, but when they realized nothing had been taken from the property, they developed alternative theories. Investigators then zeroed in on Knox, Sollecito and an innocent bar owner — despite having no physical evidence to support their implication. "The police in Perugia – they don't think Amanda Knox is acting appropriately for someone whose roommate was stabbed 47 times," Levy explained. Bremner chalked up that suspicion to cultural differences that largely shaped Italian authorities' perceptions. One image of Knox kissing Sollecito outside the murder site was plastered everywhere, but Bremner said it failed to capture the despondent looks they shared immediately after. Then, one text message – a complete misunderstanding – shifted everything, raising suspicion even higher. To learn more about the Amanda Knox case, including her hours-long interrogation, a faulty statement, the emergence of a well-known criminal and the road to Knox's eventual acquittal, subscribe to Fox Nation and begin streaming "Framed: The Amanda Knox Story" today.
