Gunner Jones ultimately pleaded guilty to two felonies after investigators focused on the period when he was alone with the child.
WEBSTER CITY, Iowa — A timeline placing Gunner Jones alone with a 10-month-old boy before the child suffered fatal injuries became a central part of an Iowa homicide investigation that ultimately ended with Jones receiving 15 years in prison.
The prosecution did not turn on a public eyewitness account of the fatal incident. Instead, records and official statements describe investigators combining medical findings with the accounts of the adults who were in the Webster City residence before the infant became unresponsive. Authorities said the child’s mother went to sleep while Jones remained awake with the boy. Medical workers later observed bruising associated with suspected abuse, and an autopsy concluded that multiple blunt-force injuries to the head caused the child’s death. More than a year later, Jones was charged with first-degree murder. He ultimately pleaded guilty to involuntary manslaughter and child endangerment.
The crucial period began before the emergency call on April 16, 2023. According to the criminal complaint, the child’s mother and Jones told law enforcement that the boy had no apparent medical issues when she went to sleep. Jones remained awake in the residence with the infant. Investigators said that sequence left him as the only person alone with the child before the injuries occurred. The complaint’s timeline was later echoed in the Iowa Department of Public Safety’s announcement of the murder charge, which said investigators had gathered evidence leading them to believe Jones had access to the infant and caused the fatal injuries.
The emergency became public at approximately 1:45 a.m., when the boy’s mother called 911. The complaint said she had discovered her son unresponsive, blue and cold to the touch. Webster City officers and medical personnel responded and the infant was taken to Van Diest Medical Center. Staff there were dealing with the immediate medical crisis when they also observed what the complaint characterized as unusual bruising consistent with inflicted child abuse. The child was transferred to Blank Children’s Hospital in Des Moines for more advanced treatment. He died later that morning.
Medical findings then provided investigators with evidence about the nature of the death. An autopsy conducted through the Iowa Office of the State Medical Examiner identified multiple blunt-force injuries to the infant’s head as the cause. The manner of death was classified as homicide. In medical-examiner terminology, a homicide classification indicates that the death resulted from another person’s actions; determining criminal responsibility remained a matter for investigators and the court system. Authorities did not publicly release the child’s full name. Court records and some news reports identified him only by the initials H.A.
The state did not announce an arrest in the immediate aftermath of the death. Instead, the Webster City Police Department and Iowa Division of Criminal Investigation continued examining the case. On Nov. 6, 2024, the Department of Public Safety said Jones, then 26, had been charged with first-degree murder. The criminal complaint accused him of acting with malice aforethought and of willfully, deliberately and with premeditation killing the infant. The charge represented the theory prosecutors were prepared to pursue at that point. Jones was entitled to the presumption of innocence on that accusation and pleaded not guilty in December 2024.
The murder charge placed the case on a path toward a jury trial, but the trial never occurred. Court dates shifted as the prosecution continued. Reporting in early 2025 identified a September trial date, while later proceedings pushed the case into 2026. At one stage, a trial scheduled for February 2026 was postponed until July. The delays meant the legal case continued well beyond two years after the child’s death. By the time the prosecution was resolved, prosecutors had added a child-endangerment charge and the first-degree murder allegation was no longer the offense on which Jones would be convicted.
Jones pleaded guilty to involuntary manslaughter and child endangerment. Published accounts conflict about the exact date on which the pleas were entered. Law&Crime reported from court records that the pleas were entered on the Friday of sentencing, while the Des Moines Register reported that Jones had pleaded to the lesser charges in June. The reliable common ground is that the pleas preceded the Sept. 25 sentencing and that Jones was not convicted of first-degree murder. The available sources do not include a full plea-hearing transcript that would resolve the date discrepancy or set out every detail of the agreement.
The change in charges altered the legal questions the case ultimately answered. Iowa’s involuntary-manslaughter law covers, among other circumstances, an unintentional death caused through the commission of a public offense other than a forcible felony or escape. State law also identifies involuntary manslaughter as an offense that can be included under a murder indictment. That differs from the original accusation that Jones deliberately and with premeditation killed the child. Because the case ended in pleas, a jury was never asked to decide whether the prosecution could prove those original allegations.
The separate child-endangerment conviction addressed Jones’ conduct involving a child under his care or control. Iowa law makes child endangerment applicable to specified people responsible for or living with children when they engage in conduct that creates substantial risks or causes certain injuries. The public reports of Jones’ sentencing do not reproduce the precise subsection or full factual basis to which he admitted. They do establish that the conviction produced a five-year prison term in addition to the sentence for manslaughter.
At the Sept. 25 sentencing, Judge Bethanie Currie ordered Jones to serve 10 years for manslaughter and five years for child endangerment, according to the Des Moines Register. The judge ordered the terms to be served one after the other rather than concurrently, making the total prison sentence 15 years. Jones was also ordered to pay $150,000 to the infant’s estate. The amount corresponds with an Iowa restitution law that requires at least $150,000 in additional restitution when a felony conviction involves acts that caused another person’s death.
The final judgment therefore rests on admitted offenses rather than the most serious allegation prosecutors initially filed. That difference is significant when describing the outcome. The medical examiner’s homicide determination remains part of the factual record, as do investigators’ conclusions about Jones’ access to the child. But the criminal judgment is for involuntary manslaughter and child endangerment. It would be inaccurate to describe Jones as having been convicted of murder because the murder charge was not decided by a guilty verdict.
Nor did the absence of a trial erase the evidence that drove the investigation. From the outset, authorities cited the bruising seen at the hospital, the autopsy findings and the adults’ descriptions of who was with the child. Those pieces formed the public explanation for why investigators focused on Jones. The Department of Public Safety said in 2024 that the joint investigation had led authorities to believe he caused the fatal injuries. The guilty pleas later provided the legal basis for his convictions, although the available public reporting does not set out every evidentiary detail that prosecutors might have presented had the case gone before a jury.
The boy’s mother has not been publicly named in the reporting reviewed for this story, and the child’s identity has remained protected beyond his initials. Defense attorney Alessandra Marcucci declined to comment after Jones was sentenced, according to the Register. No detailed statement from the family at sentencing was included in the reviewed reports. The case now stands as a conviction for two felonies arising from the April 2023 death, with Jones ordered to serve 15 years and pay the statutory restitution imposed by the court.
