Former Ship Captain Pleads Guilty To Drugging, Sexually Assaulting US Merchant Marine Academy Cadet

A former cargo ship captain pleaded guilty on Wednesday to drugging and raping a United States Merchant Marine Academy (USMMA) cadet while she was undergoing sea training aboard a commercial vessel, ending a federal trial before opening statements began.

John Merrone, 54, admitted in a Brooklyn federal court that he gave the 21-year-old cadet an intoxicant without her knowledge or consent before sexually assaulting her in September 2019 aboard the Liberty Glory, which was sailing from Bahrain to Corpus Christi, Texas.

The guilty plea came after two days of jury selection, with the victim, identified in court as Jane Doe, expected to be the first witness.

“Jane drank alcohol, I knowingly gave her an intoxicant without her knowledge or consent. Jane became incapacitated. I then had sex with her without her consent,” Merrone told the court.

He pleaded guilty to aggravated sexual abuse, sexual abuse and three counts of abusive sexual contact. Merrone remains free on a $200,000 bond and is scheduled to be sentenced on Dec. 22.

Prosecutors said he faces a possible life sentence, with sentencing guidelines estimated at between 188 and 235 months in prison.

The incident took place on Sept. 9, 2019, when the cadet was undergoing practical training aboard a U.S.-flag merchant vessel as part of the USMMA Sea Year programme.

According to prosecutors, Merrone, who was then the ship’s captain and highest-ranking officer, invited Jane Doe and another female cadet to his stateroom for a “soda.” Instead, he served them alcoholic drinks from an open bottle.

Both women lost memory of the rest of the evening after consuming the drinks.

Jane Doe woke up the following morning in her cabin wearing only a shirt and bra, without her underwear or pants. She felt nauseous, had a headache and believed she had been sexually assaulted, according to court documents.

Prosecutors said Merrone later called her back to his stateroom, told her he had “fun last night” and asked if she wanted to do it again. When she told him she did not remember what had happened, he replied that “one thing led to another.”

In another account presented by prosecutors, Jane Doe later confronted Merrone, telling him the encounter had not been consensual. Merrone then offered her money, which she refused.

Jane Doe reported the assault to her mother and a friend after returning to the United States, sought medical treatment and reported the incident to the U.S. Coast Guard in 2021.

The Department of Justice charged Merrone in May 2025. According to Jane Doe’s attorney, Ryan Melogy, the department had not prosecuted a sexual assault case involving a U.S. cargo ship in more than 40 years before bringing the charges.

Outside the courthouse, Melogy said he and his client were surprised by the guilty plea after prosecutors had spent months preparing for trial.

“We were surprised. I think the government had a very strong case … they were extraordinarily prepared,” Melogy said. He said Jane Doe turned to him after the plea and said, “It’s over.”

The five-count indictment focused on the assault of Jane Doe, but prosecutors had also alleged Merrone sexually assaulted at least three other women between 1999 and 2021. Several of those women had been expected to testify during the trial.

U.S. Attorney Joseph Nocella Jr. said Merrone had abused his position as captain to assault a cadet under his supervision.

“The defendant today admitted abusing his authority as a ship captain to carry out a heinous sexual assault on a young woman, who was under his supervision, as she embarked on a career as a mariner,” Nocella said. He added that he hoped the guilty plea would give the survivor “some measure of closure.” He also thanked the U.S. Coast Guard for its investigation.

James C. Barnacle Jr., Assistant Director in Charge of the FBI’s New York Field Office, said Merrone had “grossly violated his authority by drugging and raping a U.S. Merchant Marine cadet training aboard his ship.”

The prosecution followed renewed attention on sexual assault cases involving Merchant Marine Academy cadets after another student, Hope Hicks, publicly accused first engineer Edgar Sison of raping her during a Sea Year assignment in 2019. Melogy also represents Hicks, who was a classmate of Jane Doe.

“You can see how frequently this was happening,” Melogy said.

The Merchant Marine Academy said it remains committed to providing a safe environment for cadets both on campus and at sea and will continue working with Congress, industry partners and federal agencies to strengthen safety measures.

Congress passed the Safer Seas Act in 2022 as part of the National Defense Authorization Act, strengthening reporting requirements for sexual assault and harassment aboard U.S.-flag commercial vessels.

This was not the first time Merrone had faced trial over sexual assault allegations. In 2011, he was charged in Florida with sexual battery after another woman accused him of drugging and raping her, breaking her toe and taking nude photographs while she was unconscious.

A jury convicted him of false imprisonment and battery, but an appellate court later overturned the conviction after ruling the trial judge had not allowed the defence to recall a witness. State prosecutors did not retry the case.

Merrone, who now uses a wheelchair and cited health issues related to an injury, will remain free on bail until his sentencing on Dec. 22.
