Jurors heard how Sophia Davis’ condition deteriorated inside a Lincoln apartment before doctors determined she suffered a fatal traumatic brain injury.
LINCOLN, Ill. — The emergency began with a 19-month-old child bleeding from her mouth and struggling to breathe, then moved from a Lincoln apartment to local paramedics and finally to a Springfield hospital. More than four years later, a Logan County jury concluded that Cierra Coker was criminally responsible, convicting the 24-year-old on two counts of first-degree murder in the death of Sophia Davis.
The July 30 verdict followed a retrial in which the state reconstructed Sophia’s final medical crisis through the people who saw her condition change, the emergency call made from the apartment and doctors who treated her. Prosecutors argued that the medical emergency was not the result of an infection or underlying developmental condition but the consequence of blunt-force injuries to Sophia’s head. The defense disputed that conclusion and emphasized evidence about Sophia’s health and competing expert views. The nine-day proceeding was the state’s second attempt to win a conviction after another jury failed to reach a unanimous verdict in August 2025.
One of the prosecution’s earliest pieces of evidence was Coker’s call to 911. Jurors heard Coker describe Sophia as barely breathing and bleeding from her mouth. She also told the dispatcher that the child’s head was tilted and that she appeared to be dying. The recording captured Coker’s description of the emergency before medical professionals reached the home and became an important timestamp in the prosecution’s reconstruction of the afternoon. It did not, by itself, establish how Sophia was injured, leaving jurors to consider it alongside testimony from another child in the apartment, Sophia’s mother and the medical witnesses.
EMT Cory Sizemore testified about what he encountered after arriving at the apartment Coker shared with Sophia’s father. Sophia appeared lifeless and her lips had turned blue, according to his testimony. First responders transported the toddler to a hospital in Lincoln, and the seriousness of her condition led to an air transfer to HSHS St. John’s Hospital in Springfield. There, physicians tried to determine why a child who had recently been awake had suffered a catastrophic collapse. Sophia never recovered. Reports issued at the time and after the verdict say she died Feb. 8, 2022, two days after the emergency.
The medical investigation became the bridge between the emergency response and the murder charge. Dr. Giovanna Caprirolo testified that clinicians at St. John’s became concerned that Sophia’s cardiac arrest was linked to non-accidental trauma. Testing was negative for bacterial and viral infections. The coroner ultimately attributed Sophia’s death to traumatic brain injury caused by blunt-force injuries to the head. Court records from later proceedings described extensive injuries involving several areas of Sophia’s body and said expert evidence supported the state’s position that the fatal head injuries resulted from significant force. Prosecutors used that medical record to challenge suggestions that ordinary illness explained the collapse.
Yet the defense did not present Sophia as a child with no medical history at all. Testimony established that she had been diagnosed with autism and had early delays involving speech and mobility. Her mother, Casandra Needham, said Sophia had been teething and running a slight fever, which made her fussy. Needham also described a small head bruise from an earlier bump into a picnic table. Defense attorney Mark Wykoff told jurors they would hear conflicting medical opinions, framing the scientific evidence as a dispute rather than a settled account. The state’s burden was therefore not simply to show that Sophia died after being with Coker but to persuade jurors that trauma inflicted during that period caused her death.
Needham’s testimony brought another layer to the emergency chronology. She said Coker contacted her and reported that Sophia seemed ill. During a later video call, Needham saw the toddler with blood around her mouth and believed she was not breathing. Needham testified that she told Coker to perform CPR. According to Needham, Coker responded that she was not comfortable doing so. Needham then asked for the apartment’s address, but the video call ended. Reporting from shortly after Sophia’s death said Needham ultimately sought emergency help. Jurors could weigh those exchanges as part of Coker’s conduct during the rapidly developing crisis, separate from the question of what had caused Sophia’s injuries.
The prosecution also supplied evidence from inside the apartment that preceded the medical collapse. Sophia’s sister Paige Davis, now a teenager but 9 years old in February 2022, testified that she saw Sophia bite Coker’s finger. Paige said Coker took the toddler into another room, where Sophia cried. When Coker brought her back out, Paige said, Sophia’s mouth was bleeding and she was barely moving. Prosecutors argued that Coker became angry after being bitten and assaulted Sophia while the two were outside Paige’s view. The defense contested the state’s overall account of causation, but Paige’s testimony gave jurors a firsthand description of Sophia’s condition immediately before and after that brief interval.
That focus on a short period in the apartment came against a longer and more complicated history. About a month earlier, Sophia had returned from another visit with injuries that prompted medical attention and a child-welfare investigation. Contemporary reporting said Needham found marks on Sophia and that the toddler was not using one arm normally; hospital staff suspected abuse and contacted the Illinois Department of Children and Family Services. A later appellate court order described a possible arm fracture and facial injuries and noted that Coker was separately charged with aggravated battery related to that January episode. The record also contained disagreement among medical witnesses about whether an arm fracture was present.
Those earlier allegations became part of the legal history after Coker’s first trial ended in a mistrial. Following the deadlock, Coker sought reconsideration of her release conditions. Prosecutors instead petitioned to keep her detained. A Logan County judge concluded that the evidence presented at the first trial showed a serious threat to children that could not be sufficiently reduced through conditions such as home confinement or electronic monitoring. In February 2026, the Illinois Fourth District Appellate Court affirmed that decision. The appellate order also recorded defense evidence favorable to Coker, including her lack of prior arrests and testimony about her conduct while jailed and her past care of children.
By the second trial, both sides therefore returned to court with many of the same fundamental disputes but with a new jury deciding them. Coker’s relatives testified for the defense that she had been peaceful and nonviolent around children. Prosecutors relied on medical testimony, the sister’s account and the timing of Sophia’s decline. After nine days of evidence and argument, the jury found Coker guilty under two first-degree murder theories. Local court reporting said jurors did not make the separate finding that the crime had been accompanied by exceptionally brutal or heinous behavior indicative of wanton cruelty, a conclusion distinct from the murder verdicts themselves.
The verdict marked the first time a jury unanimously resolved the murder case. Logan County State’s Attorney Bradley Hauge said afterward that the prosecution had established that Sophia’s death resulted from Coker’s actions rather than disease or natural causes. He also singled out Paige’s testimony, noting the difficulty of returning to court years later to recount what she had seen. Illinois Attorney General Kwame Raoul, whose office helped prosecute the case, said the verdict could not erase the family’s loss but allowed the case to move toward sentencing.
Coker remains convicted while awaiting that next stage. Her sentencing is set for Oct. 6 in Logan County Circuit Court. The hearing will come more than four years after Sophia’s death, more than a year after the first trial ended without a verdict and a little over two months after the second jury accepted the prosecution’s case. Until the judge imposes sentence, the July verdict stands as the latest major development in a prosecution built from the emergency response, eyewitness testimony and contested medical evidence surrounding Sophia’s final hours.
