An Illinois mother accused of killing her two-year-old son was experiencing a 'psychotic episode' at the time, her lawyer said, as prosecutors point to her reported interest in the Lindsay Clancy trial.

Corie Walsh faces three counts of first-degree murder in connection with the death of her son, Barrett, who was found unresponsive in the family home's basement and later pronounced dead at hospital.

Prosecutors have pointed to Walsh's reported interest in the Clancy trial as part of their case, including her alleged discussions about the trial with friends shortly before her son's death.

The news came after a teenage neighbour discovered Barrett hanging from a rafter in the basement and began performing CPR before emergency crews arrived on the afternoon of 1 September. The coroner determined he died from asphyxia.

When officers reached the house, they found Walsh in the bathtub with cuts to her thighs and wrists, according to court documents. She was taken to hospital for treatment of non-life-threatening injuries, then transferred to the Will County Adult Detention Facility.

Prosecutors said Walsh told investigators she killed her son because she believed he was 'the devil' and the 'anti-Christ.' Court documents also note she had recently become 'very invested' in the Lindsay Clancy murder trial in Massachusetts.

According to a report, investigators say Walsh had been discussing the Clancy case in a group text with friends until about 12.30pm on 1 September, roughly three and a half hours before the scene was discovered.

The Clancy trial ended on Friday with a mistrial after jurors failed to reach a unanimous verdict on whether the Massachusetts mother was criminally responsible for the 2023 deaths of her three children.

Clancy's defence argued she was suffering from postpartum psychosis, a rare but severe condition that can distort a new mother's sense of reality.

Prosecutors countered that she was criminally responsible and that the killings were deliberate and planned. The mistrial left the charges unresolved, and prosecutors can seek a retrial.

In Walsh's case, prosecutors have pointed to her reported interest in the Clancy trial as part of their case, including her alleged discussions about the trial with friends shortly before her son's death. Her defence disputes that characterisation.

Attorney Andrea Lyon said Walsh was experiencing a 'psychotic episode' at the time of the alleged killing.

In a statement, Lyon said, 'This is a tragedy for the Walsh family, all of whom are mourning the loss of this child. It is also a tragedy in that Corie herself was experiencing a psychotic episode at the time this happened.' Lyon added she hoped a full investigation would provide a clearer picture of what happened.

Her firm says she took 19 capital cases through the penalty phase and none of those clients was sentenced to death.

According to CBS Chicago, Lyon, dubbed 'Angel of Death Row', is the first woman in the United States to serve as lead counsel in a death-penalty case.

The allegations have not been tested at trial, and Walsh is presumed innocent unless and until proven guilty.

The claim that she was experiencing a psychotic episode comes from her defence attorney and has not been established in court. Walsh remains in custody, and her first court appearance is scheduled for 8 September.
