Navy sailor pleads guilty to killing fellow sailor; mother questions missed warning signs

Angelina Resendiz, 21, was strangled to death by fellow sailor Jeremiah Copeland in May 2025; her death has prompted broader advocacy for military sexual violence reform.
If they would have dealt with him when he started harming women, he would never have gotten to Angie.
Resendiz's mother argues the Navy failed to act on a documented pattern of violence before her daughter's death.

In a military courtroom in June 2026, Navy sailor Jeremiah Copeland admitted to strangling 21-year-old Culinary Specialist Angelina Resendiz — a confession that closed one chapter of grief for her family while opening another about institutional failure. Resendiz's mother, Esmi Castle, now carries her daughter's memory into the halls of Congress, arguing that the Navy's failure to act on prior allegations against Copeland made his violence not just possible, but predictable. Her advocacy reflects a question as old as institutions themselves: when systems designed to protect become complicit in harm through inaction, who bears the weight of what follows?

  • Copeland's courtroom admission — 'I strangled her with my hands' — confirmed what a family had feared for over a year, replacing uncertainty with a grief that now has a name and a face.
  • Resendiz's mother alleges that four other women had already experienced Copeland's violence before he ever met her daughter, and that Navy leadership had the information needed to intervene and chose not to.
  • The plea agreement carries a minimum of forty years in prison, a dishonorable discharge, and sex offender registration — consequences that arrived too late to protect the woman they should have never needed to avenge.
  • Castle has taken her grief to Washington, joining advocacy groups pushing to open civilian court pathways for military sexual assault survivors, arguing the internal justice system cannot police itself.
  • In a moment that defied easy emotion, Castle spoke directly to Copeland after the hearing, thanked him for telling the truth, and met his mother and grandmother — refusing to let hatred be the only thing that outlasts her daughter.

On a Monday in June, Jeremiah Copeland stood before a military judge and admitted what a family had spent more than a year trying to understand: that he had strangled 21-year-old Angelina Resendiz on May 29, 2025, deliberately and with his hands, to prevent her from calling out to other sailors. Resendiz, a culinary specialist whose body had been found in a wooded area near Norfolk, Virginia, had been working toward promotion and dreaming of cooking for heads of state. That future ended in a barracks room after she saw something on Copeland's phone that disturbed her.

For her mother, Esmi Castle, the guilty plea brought a fractured kind of relief. "Now that I know, I don't have to think about it anymore," she told reporters. But the knowledge arrived alongside a harder conviction: that her daughter's death was preventable. Castle alleges that Copeland had harmed at least four other women before he ever encountered Resendiz, and that Navy leadership had both the information and the obligation to act. Some prior allegations resulted in guilty pleas; others did not. In Castle's view, the pattern was unmistakable — and was ignored.

Copeland accepted a plea agreement carrying a minimum of forty years in prison, a dishonorable discharge, forfeiture of all pay, and mandatory sex offender registration. But Castle's attention has moved past the sentence. She has traveled to Washington with advocacy groups and military families from every branch, pushing to create civilian court pathways for survivors of military sexual violence — a recognition, she argues, that the military justice system cannot be relied upon to hold itself accountable. "Nothing's changed," she said of the policies and statutes already on the books.

What distinguished Castle in the aftermath was not rage but a kind of deliberate grace. After the hearing, she spoke with Copeland directly, thanking him for his honesty. She also met with his mother and grandmother. "We technically have all lost our kids," she reflected — and expressed a quiet hope that Copeland might, across the decades ahead of him, choose to become someone different. Her daughter had been trying to grow. Castle intends to keep growing too, carrying Angelina's name into every room where the systems that failed her might finally be made to change.

Jeremiah Copeland stood before a military judge on a Monday in June and said the words that had hung over a family for more than a year: "I killed CS3 Resendiz on May 29, 2025. I strangled her with my hands." The admission brought a kind of closure, though not the kind that heals. Angelina Resendiz, a 21-year-old culinary specialist, had been found dead in a wooded area near Norfolk, Virginia, in June 2025—her cause of death ruled undetermined by the medical examiner. Now, in a general court-martial, her killer had finally named what he had done.

Resendiz's mother, Esmi Castle, told reporters that hearing Copeland accept responsibility answered questions that had tormented her since her daughter disappeared. "Now that I know, I don't have to think about it anymore," she said. But the relief came wrapped in something harder to swallow: the conviction that her daughter's death might never have happened at all. According to Castle, Copeland had a documented pattern of harming women before he ever met Resendiz. There were four other women, she said, whose experiences should have triggered the kind of intervention that could have stopped him.

The facts of that May evening are stark. Copeland and Resendiz drank together in his barracks room. They kissed. Then she saw something on his phone that upset her. What happened next, Copeland admitted in court, was that he strangled her—not in a moment of rage, but deliberately, to keep her from calling out and drawing the attention of other sailors. The plea agreement he accepted carries a minimum of forty years in prison, a dishonorable discharge, forfeiture of all pay, and a requirement to register as a sex offender.

But Castle's focus has shifted beyond Copeland himself. She has become convinced that the Navy's institutional failures made her daughter's death preventable. "If they would have dealt with him when he started harming women, he would never have gotten to Angie," she said. The allegations against Copeland before Resendiz's death were not uniformly prosecuted—some resulted in guilty pleas, others did not. Yet Castle argues that the pattern should have been impossible to miss, and that military leadership chose not to see it, or chose not to act.

Since her daughter's death, Castle has traveled to Washington with advocacy groups and other military families, pushing for systemic change. Her primary goal is to create a pathway for military sexual assault and violence survivors to pursue claims in civilian courts, outside the military justice system. She has met relatives of service members from every branch, and their stories have convinced her that what happened to Angelina Resendiz is not an anomaly but a symptom. "Nothing's changed," Castle said. "We have statutes, and we have policies, and we have procedures that were implemented by Congress to protect service members from this type of violence. And nothing's changed."

What is perhaps most striking is Castle's refusal to hate. After the hearing, she spoke directly with Copeland. "I thanked him for telling the truth," she said. She also met with his mother and grandmother, who had attended the proceedings. "We technically have all lost our kids," Castle reflected. Rather than anger, she expressed a kind of hard-won hope—that Copeland, in the decades ahead of him in prison, might choose to become someone different. "He still can choose better," she said.

Resendiz had been working toward promotion, dreaming of joining the Navy's elite culinary competition team, imagining a future where she might cook for presidents and world leaders. "She was trying to grow," her mother said. "She was doing everything she could to get ready for promotion." That future is gone. What remains is Castle's determination to ensure that the systems meant to protect service members actually do their job—and her insistence that the military justice system alone cannot be trusted to deliver accountability.

If they would have dealt with him when he started harming women, he would never have gotten to Angie.

Inventor

Why did Castle meet with Copeland after the hearing? That seems almost impossible to understand.

Model

She separated the person from the system. Copeland admitted what he did—that mattered to her. But she also saw his mother and grandmother grieving. She wasn't forgiving him so much as refusing to let hatred consume the space where advocacy could live.

Inventor

And the four other women—why weren't those cases enough to stop him before Resendiz?

Model

That's the question Castle keeps asking. The allegations existed. Some led to guilty pleas, some didn't. But there was no mechanism that forced the Navy to see the pattern and act on it. Each case was treated separately, in isolation.

Inventor

So she's arguing the system is designed to fail?

Model

Not designed to fail, exactly. But structured in a way that allows failures to compound. A woman reports assault. It gets handled internally. Another woman reports. Same thing. By the time you see the pattern, it's too late.

Inventor

What does she want changed?

Model

She wants military sexual assault survivors to be able to take their cases to civilian courts. Right now they're trapped inside a military justice system that has every incentive to protect itself.

Inventor

And does she think that would have saved her daughter?

Model

She thinks it would have created accountability earlier. If the first woman Copeland harmed had been able to pursue a civilian case, if that had created real consequences, Resendiz might still be alive.
