Mary Ann McKinzy was returned to Oregon after U.S. Marshals found her months after James S. Miller’s death.
PORTLAND, Ore. — More than eight months after James S. Miller was found dead in a Portland apartment parking lot, U.S. Marshals located Mary Ann McKinzy in Bakersfield, California, bringing a cross-state search to an end and returning the 55-year-old woman to Oregon to face a second-degree murder charge.
The arrest on Aug. 5, 2026, and McKinzy’s extradition to Multnomah County on Sept. 18 marked the latest confirmed steps in an investigation that began with Miller’s death on Nov. 28, 2025. Portland police said McKinzy was also booked on first-degree assault and negligent homicide charges. The official announcement identified her as the suspect detectives had been seeking, but it offered little detail about why investigators believed she was responsible. That detail emerged through court records described in later reporting, which portray a volatile confrontation between people who had been in a relationship.
According to those reports, the path to the parking lot began with a lottery ticket. Miller, 75, won $3,200 and gave McKinzy $1,700, prosecutors say. They allege McKinzy later took another $800 from him without permission. Miller then told an acquaintance he intended to find her and recover the money, according to reporting on a probable cause affidavit. The records do not identify the game he played or the place where the winning ticket was purchased, leaving the lottery itself as background to the criminal case rather than a separately documented event.
A friend agreed to drive Miller to McKinzy’s apartment complex on the morning he died. That friend later told police he did not know what Miller planned to do, according to the reported affidavit. At the complex, the two men found McKinzy in her car. Miller went to the driver’s side and demanded that she open the door. The friend said he heard Miller threaten to break the window if she refused. That account placed McKinzy inside a vehicle while Miller confronted her from outside, a setting that would soon become central to both the homicide allegation and her stated fear.
Miller then allegedly instructed the friend to use his car to prevent McKinzy from leaving. McKinzy backed into the friend’s vehicle, according to the witness account. The friend got out to inspect the damage and said he saw Miller throw a knife at McKinzy’s car. Surveillance footage described in court records allegedly shows Miller stabbing the vehicle’s tires. The sequence matters because prosecutors accuse McKinzy of acting intentionally when she struck Miller, while the same records document threatening and destructive conduct by Miller immediately beforehand.
McKinzy then reversed and drove over Miller, prosecutors allege. The friend told police that he yelled for her to move the car and that McKinzy said Miller was “trying to kill me” before leaving the scene. Public reports describing the affidavit say prosecutors believe she struck Miller on purpose. They also show why the case may involve arguments about danger and justification. No source reviewed for this article contains a final judicial ruling on those issues, and the charges against McKinzy remain allegations.
The first emergency information police received pointed investigators in a different direction. Officers were dispatched on a report that someone had been stabbed. Miller was pronounced dead at the scene, but the Multnomah County Medical Examiner later found that he died from blunt force trauma and ruled the death a homicide. The correction made the vehicle the central alleged instrument in Miller’s death. At the same time, the knife retained evidentiary importance because investigators say Miller had used it against McKinzy’s car just before the fatal encounter.
Investigators soon located what they believed was the relevant vehicle at a tire shop. Published accounts of the affidavit say a hubcap recovered from the parking lot matched McKinzy’s car and that another matching hubcap was found inside the vehicle. The car also had damage to the hood described as consistent with the knife. Reports say personal belongings or documents tied to McKinzy remained in the vehicle. Together, those details helped police connect the car and its owner to the scene after McKinzy was no longer readily available for questioning or arrest.
The gap between Miller’s death and McKinzy’s capture then became a defining part of the case. Detectives obtained an arrest warrant, but published accounts say she had already left Oregon or did so shortly afterward. Portland police have not publicly detailed every step in the search, and the official release does not say when investigators learned she was in California. What it does confirm is that the U.S. Marshals Service found and arrested her in Bakersfield on Aug. 5, 2026.
McKinzy was initially held in the Kern County Jail, police said, before being transported back to Portland. On Sept. 18, she was lodged in the Multnomah County Detention Center. The return placed her within Oregon’s court system and allowed the homicide case to proceed locally after months in which investigators had a suspect but not a defendant in custody. Portland police publicly thanked the U.S. Marshals Service for its assistance.
The charges announced after extradition are serious, but the public record available through the sources reviewed here remains incomplete. Police listed second-degree murder, first-degree assault and negligent homicide. Their release did not explain the elements prosecutors intend to prove under each count or how they will present the relationship among the charges. It also did not address possible defenses. Detailed allegations about the parking-lot encounter appear in reports on the probable cause affidavit rather than in the brief police announcement.
That distinction becomes especially important because the alleged facts do not describe a one-sided confrontation. Miller was the person who died, and prosecutors accuse McKinzy of intentionally using a vehicle against him. But court-record reporting also says Miller threatened to break her window, helped block her car and damaged the vehicle with a knife. McKinzy’s statement that he was trying to kill her appears in the same reported narrative. A court will have to determine what weight, if any, those circumstances carry when assessing intent and any defense theory.
The months-long search also should not be treated as proof of guilt. Leaving the state can become part of a prosecutor’s narrative, but the sources reviewed for this story do not establish why McKinzy went to California or what she told investigators about her departure. The official release simply states that federal marshals located her there and that she was extradited. Any argument that her travel shows consciousness of guilt would have to be supported and litigated rather than assumed from the arrest history alone.
Law&Crime reported that McKinzy was scheduled for a court appearance on Sept. 29. As of Nov. 8, no later reliable public report located for this story established the result of that proceeding or announced a trial date. The absence of a documented update means the most recent confirmed procedural facts remain her August arrest, September extradition and booking on the three charges.
Portland police continue to seek information from anyone who has not already spoken with investigators and have asked tipsters to reference case No. 25-325754. For now, the case links two distinct timelines: the few minutes of a parking-lot confrontation that ended with Miller’s death and the many months that passed before McKinzy was arrested in another state. The first will determine the substance of the criminal case; the second explains why the prosecution only recently moved into public view.
