A suburban Illinois mother has been charged with murder after she is accused of killing her 2-year-old son and attempting to take her own life, according to police and court documents. The incident took place in Frankfort, an affluent village about 35 miles southwest of Chicago. The child, Barrett Walsh, was found hanging in the basement, and his mother, Corie A. Walsh, was discovered in a bathtub in what appeared to be a suicide attempt. Walsh, 40, was charged with three counts of first-degree murder on Friday, police announced. According to prosecutors, Walsh had recently become deeply involved in the high-profile murder trial of Lindsay Clancy, who was accused of killing her three children in January 2023. Clancy's trial had been widely publicized and ended in a mistrial earlier this week. Prosecutors noted that Walsh had been actively discussing the case with friends in group text messages up until just three and a half hours before the incident at her home. At the time, the jury in Clancy’s trial was in deliberations. Frankfort police responded to the home just after 4 p.m. on Tuesday after receiving a report of an unresponsive child. When officers arrived, a neighbor was performing CPR on the toddler, who had been found hanging in the basement. The neighbor took the child down and attempted CPR while calling 911, but the child was already cold and had no pulse, prosecutors said. The child was transported to a local hospital, where he was pronounced deceased. The Will County Coroner’s Office ruled the death an apparent homicide, with preliminary findings indicating the child died from asphyxia due to ligature compression of the neck. Officers found Walsh in the bathroom of the upstairs master bedroom, lying in a tub fully dressed and "surrounded by bloody water." She had cuts to her wrists and thighs, and was taken to the hospital with non-life-threatening injuries. Walsh reportedly told officers she killed her son because he was the "devil" and the "anti-Christ." A neighbor said she found Walsh with a knife in her hands, "actively harming herself." The neighbor took the knife and threw it into the sink, where it was later collected as evidence. After the neighbor removed the knife, Walsh asked why she had done so, saying she was trying to kill herself. Walsh then told the neighbor that "Bear," the child’s nickname, was "in the basement." Police said the preliminary investigation suggests the case is a domestic-related homicide. Walsh’s husband was out of town at the time, and an infant was at home and unharmed, prosecutors said. Two school-aged children had returned home around the time Barrett was found and were also physically unharmed. Walsh allegedly made statements about harming her other children and intending to harm her husband upon his return. After being hospitalized, she described to officers how she killed Barrett, which matched evidence found at the scene. Walsh was in custody Friday night and was being held for medical treatment. Once released, she will be transferred to the Will County Adult Detention Facility. It is not yet clear if she has retained an attorney. Frankfort police called the case a "heartbreaking tragedy" and asked the community to keep the family in their thoughts and prayers.
