Prosecutors said the child’s mother changed treatment locations while hiding injuries blamed on her boyfriend.
DETROIT, Mich. — A 3-year-old boy was treated at at least five medical facilities before dying from injuries blamed on his mother’s boyfriend, according to prosecutors who said the changing locations helped conceal a prolonged pattern of abuse.
The medical visits became a central part of the criminal cases against Michael Yharbrough and Brianna Simmons. A jury convicted Yharbrough of felony murder, torture and first-degree child abuse. Simmons, the boy’s mother, pleaded guilty to second-degree child abuse and testified against him. Prosecutors said she continued seeking care for her injured child while hiding who was hurting him inside their Detroit home.
Public accounts do not name the five facilities or provide a complete list of the boy’s visits. It is unknown whether they were hospitals, emergency departments, clinics or urgent-care centers. The record also does not show whether the facilities used compatible electronic systems or obtained records from one another. Those gaps are important because prosecutors described injuries that accumulated over time. A provider who saw one fracture might not have known that another facility had treated an earlier injury. Authorities alleged that Simmons understood that separation and used it to prevent medical workers from seeing the entire pattern.
The changing facilities did not mean the child remained outside the child-welfare system. Assistant Wayne County Prosecutor Brittany Johnson said Children’s Protective Services removed the boy from Simmons more than once. He was later returned to his mother and Yharbrough, Johnson told the court, and suffered additional broken bones after each return. The available reports do not state where he lived during the removals, how long the placements lasted or what evidence led officials to send him home. They also do not show whether the medical visits occurred before, between or after particular removals.
Prosecutors said the abuse began after Simmons allowed Yharbrough to move into her home on Rutherford Street on Detroit’s west side. They accused him of repeatedly beating and torturing her young son. Simmons was not portrayed as a parent who remained unaware of hidden violence. Instead, the state argued that she saw the consequences, took the child for treatment and then protected Yharbrough by concealing the source of the injuries. Johnson said Simmons “aided and abetted” her boyfriend and that her actions contributed to the child’s death.
The boy died March 1, 2025, following what authorities described as a final assault in late February. Public reporting has not included his name, a full autopsy report or a complete medical description of the fatal injuries. It is also unclear whether he died at the Rutherford Street home or after emergency treatment. Those details were likely addressed through evidence in the criminal case, but they have not appeared in the limited public summaries available after the verdict.
Simmons was arraigned in June 2025 on first-degree murder, torture and first-degree child-abuse charges. A magistrate ordered her held without bond and barred her from contacting her older children. Prosecutors said the older children could become witnesses, indicating that investigators were looking beyond medical records for information about the household. The children’s ages, observations and eventual involvement in the case have not been made public.
Yharbrough was not in custody when the allegations first drew public attention. Later records indicated that he was arrested in August 2025. The time between the child’s death, the charging decisions and Yharbrough’s arrest has not been fully explained. Investigators in a fatal child-abuse case may need to wait for medical conclusions, compare records, interview family members and determine which injuries can be attributed to particular events. The five-facility history would have added another layer of record gathering and review.
The medical evidence likely served more than one purpose. It could document the existence, timing and severity of the child’s injuries. It could also help establish whether those injuries were consistent with explanations given by caregivers. Finally, the visits could show what Simmons knew about her son’s condition. Prosecutors relied on that last point when accusing her of helping conceal the abuse. Public reports do not reveal what she told individual medical workers or whether those accounts changed from one facility to another.
Health care workers are among the professionals required under Michigan law to report suspected child abuse or neglect. A report can lead to an investigation, but it does not by itself determine whether a child is removed or returned. Those decisions may involve child-protection investigators, agency supervisors, police, lawyers and family-court judges. The confidential nature of juvenile records prevents a clear public accounting of which providers reported concerns in this case and how officials responded to each report.
Simmons’ legal position changed almost a year after her arraignment. On May 8, 2026, she pleaded guilty to second-degree child abuse. Prosecutors dismissed the original murder, torture and first-degree child-abuse charges in exchange for the plea and her testimony against Yharbrough. They recommended a sentence of one year in jail followed by three years of probation. The agreement greatly reduced Simmons’ possible punishment while giving the state a witness with direct knowledge of the home.
Yharbrough chose to stand trial. Jurors heard about two weeks of evidence before convicting him on all three counts. The felony-murder verdict established that the jury found the child died during the commission of an underlying felony. The torture conviction addressed intentional conduct that caused extreme suffering. The first-degree child-abuse conviction required proof that Yharbrough intentionally inflicted serious physical or mental harm. The verdicts rejected any defense claim that prosecutors had failed to connect him to the abuse beyond a reasonable doubt.
Simmons’ testimony would have come with an obvious credibility issue because she received a reduced charge. Jurors could consider that benefit while weighing her account against medical evidence and other testimony. The public reports do not provide the trial transcript, identify all of the medical experts or explain how Yharbrough’s attorneys challenged Simmons. The guilty verdicts show that the jury accepted the prosecution’s case as a whole, but they do not reveal which evidence jurors found most persuasive.
The medical providers have not been publicly accused of criminal conduct. Nor has a public inquiry concluded that a particular doctor, nurse or hospital knowingly overlooked the abuse. A criminal trial focuses on the guilt of the named defendants. Determining whether a facility followed reporting rules or adequately reviewed the child’s history would require access to records that remain private. The same distinction applies to the child-welfare officials who participated in the removals and returns.
The case highlights how a child’s history can become fragmented when treatment occurs in different locations. One file may contain an X-ray, another may record bruising and a third may include a caregiver’s explanation. Unless those records are connected, the pattern can remain incomplete. Prosecutors said that fragmentation was not accidental here. They alleged that Simmons deliberately moved between facilities to keep the repeated injuries from being recognized as evidence of abuse.
Sentencing hearings had been scheduled for June 23 for Simmons and June 26 for Yharbrough in Wayne County’s Third Circuit Court. Felony murder can carry life imprisonment without parole in Michigan. The other convictions also expose Yharbrough to lengthy prison terms. Public reports available for this update did not provide verified sentencing results for either defendant.
The criminal cases now establish that Yharbrough was convicted of causing the fatal abuse and that Simmons admitted failing to protect her child. What remains unknown is what each medical facility saw, what each provider reported and whether anyone had assembled the complete history before the boy returned to the Rutherford Street home.
