The 19-month-old’s mother had sought help after an earlier injury before a second incident ended with the toddler’s death.
LINCOLN, Ill. — Weeks before 19-month-old Sophia Davis suffered the traumatic brain injury that killed her, her mother had already reported concerns about injuries discovered after an earlier visit with the child’s father. Four years later, a Logan County jury convicted the father’s former girlfriend, Cierra Coker, of first-degree murder after prosecutors linked Sophia’s fatal injuries to another period when Coker was caring for her.
The July 30 verdict put a criminal judgment at the end of a timeline that began well before the fatal emergency. Contemporary reporting from March 2022 said Sophia’s mother, Casandra Needham, contacted the Illinois Department of Children and Family Services after Sophia returned from an overnight visit in early January with visible injuries and difficulty moving an arm. A hospital visit prompted a child-abuse report, according to Needham. That earlier episode later became the basis for aggravated-battery charges against Coker and appeared in court proceedings leading up to her murder retrial. The murder case itself required two juries before prosecutors obtained a unanimous conviction.
Needham told Capitol News Illinois shortly after Sophia’s death that she found scratches and bruising on the toddler after the January visit and took her to HSHS St. John’s Hospital in Springfield because Sophia was not moving her left arm normally. Needham said a doctor suspected child abuse and contacted DCFS. She also said a child-welfare investigation followed but that she was told the allegations were expected to be classified as unfounded. The 2026 appellate record separately described evidence of a possible broken arm and facial injuries while noting that a defense medical witness later disputed the existence of an arm fracture.
By early February 2022, Sophia was again visiting her father’s home in Lincoln. The record developed at trial placed Coker in charge of Sophia and two other young children on Feb. 6 while Sophia’s father was at work. The toddler was teething, and Needham testified that she had a slight fever and was fussy. She also had a small contusion from bumping her head on a picnic table. Those relatively ordinary childhood conditions would later become part of a much larger medical dispute, with the defense pointing to Sophia’s health history while prosecutors argued that none of it accounted for the catastrophic injuries that followed.
The most direct account from inside the apartment came from Sophia’s older sister Paige Davis, who was 9 at the time. Paige testified that she saw Sophia bite Coker’s finger. She then saw Coker take the toddler into another room, where Sophia began crying. According to Paige, Coker later came back out with Sophia, whose mouth was bleeding and who was barely moving. The testimony was significant because it described a marked change in the toddler over a short period and placed Coker alone with her during part of that interval. Prosecutors argued the bite angered Coker and that she assaulted Sophia in the other room.
Needham encountered the crisis from a distance. She testified that Coker told her Sophia appeared sick and later contacted her by video as the child’s condition worsened. Needham saw blood around Sophia’s mouth and believed she was not breathing. She said she instructed Coker to perform CPR, but Coker replied that she was uncomfortable doing so. Needham then sought the address so emergency assistance could be directed to the home. Earlier reporting said Needham also tried to secure help herself. Coker ultimately called 911, telling a dispatcher that Sophia was barely breathing and bleeding from the mouth and describing her head as tilted in an alarming position.
When EMT Cory Sizemore arrived, he testified, Sophia appeared lifeless and her lips were blue. Emergency crews transported her to a hospital in Lincoln before she was flown to St. John’s in Springfield. There, Dr. Giovanna Caprirolo testified, the medical team became concerned that Sophia had experienced cardiac arrest associated with non-accidental trauma. Tests did not identify a bacterial or viral infection. The coroner later determined that Sophia died from a traumatic brain injury due to blunt-force injuries to her head. Sophia died Feb. 8, 2022, according to contemporary reporting and the official account issued around the 2026 verdict.
For prosecutors, those medical findings tied the emergency in February to a violent act rather than disease. For the defense, they were a point to contest. Sophia had been diagnosed with autism and had developmental delays involving speech and mobility, testimony showed, and defense attorney Mark Wykoff told the second jury it would hear competing expert interpretations of the evidence. The appellate record also preserved disagreement over the earlier January injury, including testimony from a doctor who said an autopsy did not show evidence of a broken arm. The defense sought to create reasonable doubt by separating established facts about Sophia’s poor condition from the prosecution’s conclusion about who caused it and how.
Coker’s background was another part of that defense presentation. Relatives testified during the retrial that she had been peaceful around children. Earlier detention proceedings documented that she had no identified juvenile or adult arrest record before the case and no disciplinary infractions while incarcerated. Family members said they could supervise her if she were released, and character statements described previous occasions on which she had cared for children safely. Those details were relevant to the broader portrait the defense offered, although the murder jury ultimately had to decide the narrower question of whether the state proved the charged conduct involving Sophia beyond a reasonable doubt.
The first jury could not answer that question unanimously. Coker’s August 2025 trial ended in a mistrial after jurors deadlocked. In the months that followed, Coker sought reconsideration of her pretrial status, but prosecutors asked that she remain detained. The Logan County court sided with the state, concluding that the evidence presented at trial showed a threat specifically to children that release conditions could not sufficiently mitigate. The Illinois Fourth District Appellate Court affirmed that ruling in February 2026. That decision did not determine Coker’s guilt; it resolved only the dispute over whether she should remain detained while awaiting another trial.
The retrial began in July with a new jury and ended after nine days of proceedings. Jurors found Coker guilty on two first-degree murder counts. Local court coverage reported that they did not make a separate finding that the killing was accompanied by exceptionally brutal or heinous behavior indicative of wanton cruelty. The distinction is important because it accurately defines the verdict: the jury found the elements necessary for the murder convictions while declining that additional characterization. The verdict replaced the uncertainty left by the earlier mistrial with a unanimous finding of criminal responsibility for Sophia’s death.
Afterward, Logan County State’s Attorney Bradley Hauge framed the case around Sophia and credited her sister for returning to testify years after witnessing the events at age 9. He said the prosecution had established that Sophia’s death was not caused by disease or natural causes. Illinois Attorney General Kwame Raoul, whose office worked with the Logan County prosecutor, likewise said the verdict could bring accountability but could not remove the loss experienced by the toddler’s family. Neither statement changed the long history that preceded the verdict, including the concerns Needham said she raised before Sophia’s death.
Coker is scheduled to return to Logan County Circuit Court for sentencing on Oct. 6. The proceeding will be the next formal step in a case that has touched criminal court, child-welfare investigations, medical testimony and appellate review. The murder convictions resolve Coker’s guilt at the trial-court level, while the record also preserves the broader sequence surrounding Sophia’s final month: an earlier report of suspected abuse, another period in Coker’s care, the toddler’s sudden collapse, a disputed medical case, a deadlocked first jury and, finally, a unanimous verdict at the second trial.
