(NEW YORK) — Accused Gilgo Beach, New York, serial killer Rex Heuermann might change his plea to guilty and admit to the murders at his scheduled court appearance on Wednesday, sources familiar with the case told ABC News.
Heuermann, a New York City architect, was arrested in 2023 and has pleaded not guilty to killing seven women whose remains were found on New York’s Long Island.
His trial is set for September.
The first victim was Sandra Costilla, killed in 1993. Valerie Mack was killed in 2000 and Jessica Taylor was killed in 2003. Partial remains of Taylor and Mack were found near Gilgo Beach and in Manorville on Long Island, while Costilla was found in North Sea on Long Island.
Maureen Brainard-Barnes was killed in 2007 and found near Gilgo Beach. Megan Waterman, Melissa Barthelemy and Amber Lynn Costello were killed between 2009 and 2010 and also recovered near Gilgo Beach.

(NEW YORK) — The U.S. Army special forces soldier who was indicted last week on charges of using classified information about the capture of Venezuelan President Nicolas Maduro to make more than $400,000 on Polymarket is set to appear in a Manhattan courtroom Tuesday.
Master Sgt. Gannon Ken Van Dyke is scheduled to be arraigned following his release last week on a $250,000 bond.
In what is believed to be the first case of insider trading on a prediction market, prosecutors alleged that Van Dyke used classified information from his work in the planning and execution of the Maduro capture to place 13 bets on the outcome of the operation.
Prosecutors allege that Van Dyke placed bets on Dec. 27 through the evening of Jan. 2 — hours before soldiers entered Venezuelan airspace for the pre-dawn operation. After President Donald Trump made the operation public later that day, Van Dyke allegedly profited $409,881 from his $33,034 in bets.
“The defendant allegedly violated the trust placed in him by the United States Government by using classified information about a sensitive military operation to place bets on the timing and outcome of that very operation, all to turn a profit,” U.S. Attorney for the Southern District of New York Jay Clayton said in a statement last week. “That is clear insider trading and is illegal under federal law.”
The indictment also alleges that Van Dyke attempted to hide the evidence of the illegal trades by attempting to delete his Polymarket account and changing the email address associated with his cryptocurrency exchange account.
Following his arrest on Thursday, Van Dyke briefly appeared in a North Carolina courtroom on Friday. After acknowledging that he understood the charges and potential penalties, he signed a bond and agreed to surrender his passport, limit travel to parts of New York and North Carolina, and no longer possess a firearm unless it is part of his active military service.
His case is being overseen in New York by U.S. District Judge Margaret Garnett, who is also presiding over the high-profile federal case against alleged UnitedHealthcare CEO assassin Luigi Mangione.
Amid mounting criticism of prediction markets for allegedly enabling insider trading, Polymarket CEO Shayne Coplan said his company is “constantly” monitoring for suspicious activity and referring cases to authorities. Coplan argued that the public nature of prediction markets makes it easier to crack down on insider trading.
“The transparency afforded by onchain markets makes global compliance more effective than ever. Every trade is public, permanent, and auditable. Bad actors leave a trail,” he said.

(NEW YORK) — Ghislaine Maxwell, the convicted co-conspirator of the late sex offender Jeffrey Epstein, is again asking a federal judge in New York to vacate her sex trafficking conviction and release her from prison.
Maxwell submitted her new request, which she wrote herself, to federal prosecutors in New York, who said they received “a FedEx envelope — marked with a ‘ship date’ of April 16, 2026 — that contained a USB drive with the defendant’s amended motion and exhibits,” according to a letter to the district court that was posted online early Monday morning.
Prosecutors did not disclose details of Maxwell’s argument, which has not yet been filed on the public docket, but said it “seems to have some overlap” with her original motion to dismiss that district and appellate courts rejected in 2024. The U.S. Supreme Court subsequently declined to hear her appeal.
Having exhausted all of her direct appeals, Maxwell filed a habeas petition this past December in which she contended that “substantial new evidence has emerged” regarding her case. Maxwell’s submission this week comes after the district court judge, in February, allowed Maxwell to submit an amendment to that petition following the Justice Department’s release of the Epstein files.
Maxwell previously argued, unsuccessfully, that her conviction and her 20-year sentence should be tossed because she did not receive a fair trial and was covered by the non-prosecution agreement that Epstein’s attorneys had negotiated for him as part of the wealthy financier’s 2028 plea deal.
She also argued her conviction was based on vague allegations of “grooming” victims that did not amount to a crime.
Maxwell is currently serving her sentence for aiding and participating in Epstein’s trafficking of underage girls, which involved a scheme to recruit young women and girls for massages of Epstein that turned sexual. Federal prosecutors in New York said Maxwell helped Epstein recruit, groom and ultimately abuse girls as young as 14.
In an interview with then-Deputy Attorney General Todd Blanche last month, Ghislaine Maxwell said nothing during the interview that would be harmful to President Donald Trump, telling Blanche that Trump had never done anything in her presence that would have caused concern, according to sources familiar with what Maxwell said.
Epstein died by suicide in a New York jail in 2019.

(TAMPA, Fla.) — The remains of one of the two missing University of South Florida doctoral students were discovered by investigators Friday and his roommate was taken into custody, authorities said.
Joseph Maurer, of the Hillsborough County Sheriff’s Office, told reporters that investigators found the remains of Zamil Limon on the Howard Frankland Bridge in Tampa Friday morning. Investigators have been searching for Limon and fellow USF doctoral student Nahida Bristy since they went missing on April 16.
“We are still actively searching for Nahida,” he told reporters during a news conference Friday.
Maurer said investigators received a 911 call for a domestic violence disturbance around 9 a.m. at a residence where Limon’s roommate, Hisham Abugharbieh, had barricaded himself.
Abugharbieh was previously interviewed by police during their investigation into the disappearances, Mauer said.
Following a brief standoff, the suspect surrendered, Maurer said.
Abugharbieh is being charged with several counts, including tampering with evidence, failure to report death and domestic violence, according to Maurer.
The cause of Limon’s death is being determined, Maurer said. He had no further details about Bristy’s condition.
Limon and Bristy, both 27, were last seen at separate locations in the Tampa area on April 16, according to the USF Police Department.
On Thursday, officials received new information to warrant upgrading their status from missing to endangered, which indicates they are at risk of physical injury or death, the Hillsborough County Sheriff’s Office said.
The sheriff did not provide any more details about the investigation or search efforts.
Limon and Bristy are friends, and a mutual acquaintance reported them missing, campus police said.
Limon, who was pursuing a degree in geography, environmental science and policy, was last seen at his Tampa residence at approximately 9 a.m. on April 16, according to police.
Bristy, who is studying chemical engineering, was last seen at the USF Tampa campus at the Natural & Environmental Sciences Building at approximately 10 a.m. that day, police said.
Anyone with information on her whereabouts is urged to call the University of South Florida Police Department at 813-974-2628.
