Margaret Williams was found dead there in December 2024, and her parents say the setting still defines how they view the charge against Jayden Frost.
PHOENIX, Ariz. — Long before arguments over charging language and trial strategy, this case was fixed in public memory by one image: a 21-year-old woman found dead on a baseball field near 40th Street and Ray Road as daylight came up over south Phoenix.
That setting still shapes the case now. Margaret “Maggie” Williams’ parents have described the park as the place where their daughter was strangled, left behind and exposed to animals. Investigators later identified her former boyfriend, Jayden Frost, as the suspect, but the family’s public grief has never moved far from the field itself. In their view, the details of where Williams was found and what police say happened there make the negligent homicide charge feel too limited for the facts already known.
The known facts from the scene are among the starkest in the public record. Phoenix police said officers responded at about 7 a.m. on Dec. 7, 2024, after Williams was found in the baseball fields. The first advisory said there were no obvious signs of trauma when detectives initially worked the scene, and the medical examiner took over the body. Court documents later described by Law & Crime painted a harsher picture, saying Williams had bruising and abrasions on her neck, injuries to her face, one sock still on, no shoes, and bodily fluid coming from her mouth and nose. The same report said Frost and another person later found her surrounded by coyotes.
Only after the autopsy did the official understanding of the scene fully change. On Feb. 5, 2025, Phoenix police said the Medical Examiner’s Office had ruled the death a homicide, moving the case into the hands of homicide detectives. From there, the park became not just the place where Williams was discovered, but the place investigators say she spent her final hours with Frost. Reporting on the affidavit said the two had been dating for about two months, had been drinking alcohol and using marijuana, and had been dropped off at the park the night before she was found.
Police said Frost’s description of those hours changed over time. His first account, according to court reporting, was that he left around 11 p.m. to charge his phone at a grocery store while Williams stayed behind. He said he returned about an hour later and could not find her. Later, investigators said, Frost admitted that the two were engaged in sexual activity on the field and that he choked Williams during it. He described the choking as consensual rough sex, but police said he recognized she was in distress, saw foam coming from her mouth and then panicked. Instead of calling 911, officers said, he threw away her phone and earbud case and made up a story because he thought the truth would not be believed.
The family’s anger is rooted in the difference between those allegations and the charge that followed. Phoenix police said Frost was extradited to Arizona on Dec. 31, 2025, and booked into jail. Yet prosecutors filed negligent homicide. In interviews with local television, Williams’ parents said that choice failed to match either the brutality of the scene or the admissions attributed to Frost. Mike Williams told KPNX that the family did not understand why the state had not pursued murder or manslaughter. The Maricopa County Attorney’s Office responded, in a statement quoted by ABC15, that prosecutors filed the charge supported by the available evidence and legal standards and would consider modifying it if new evidence were brought forward.
What comes next is more formal, but it does not erase the physical reality that first brought attention to the case. Local reporting has said Frost’s trial is scheduled for May 13, 2026. Between now and then, lawyers will argue over the meaning of his statements, the weight of the forensic findings and whether the charge reflects criminal negligence or something more serious. The public discussion may center on legal categories, but the evidence jurors will hear begins with a body on a field and a scene that investigators later said was part of a homicide.
That is where the case still stands: in court on paper, but in the minds of Williams’ family and much of the public, still on the baseball field where the investigation started and where the next phase of the fight over accountability was set in motion.
