FRANKFORT, Ill. — An Illinois mother is facing three counts of first-degree murder in the death of her 2-year-old son in a case drawing national attention because prosecutors say she had been closely following and discussing the Lindsay Clancy murder trial just hours before her son was found.

Corie A. Walsh, 40, of Frankfort, is charged in the Sept. 1 death of her son, Barrett Walsh. Frankfort police responded shortly after 4 p.m. to a home in the 22700 block of Brook Stone Court after a neighbor called 911 and attempted CPR on the child.

According to court filings described by multiple news organizations, the neighbor found Barrett unresponsive in the basement. He was transported to a hospital and later pronounced dead. Preliminary autopsy findings cited in court records indicated he died from asphyxia caused by ligature compression of the neck. Final findings remain subject to additional reports.

Prosecutors Detail Statements to Investigators

Prosecutors allege Walsh was found upstairs after apparently injuring herself. Court documents say she subsequently told investigators that she believed her son was the “devil” and the “anti-Christ.” Prosecutors contend Walsh described what happened and that her account was consistent with evidence investigators found at the home.

An infant who was inside the home was unharmed. Two additional school-age children returned to the home around the time the scene was discovered, according to reports citing the court filing. Walsh’s husband was out of state.

Prosecutors are seeking to keep Walsh detained before trial. Their petition also alleges she made statements about harming her other children and her husband.

The Lindsay Clancy Connection

The case has attracted particular attention because witnesses told investigators Walsh had recently become “very invested” in the Lindsay Clancy murder trial in Massachusetts.

According to the court filing, Walsh was actively discussing the Clancy case in a group text with friends until approximately 12:30 p.m. on Sept. 1 — about three and a half hours before the scene at the Frankfort home was discovered.

Clancy was charged with killing her three children in Massachusetts in 2023. Her defense argued at trial that she was suffering from postpartum psychosis and was legally insane at the time of the killings. Prosecutors argued she remained criminally responsible. Her 2026 trial ended Sept. 4 in a mistrial after jurors were unable to reach a unanimous verdict.

Authorities have not established that the Clancy case caused or inspired Barrett Walsh’s death. The publicly reported evidence establishes that Walsh was following and discussing the trial shortly beforehand, but investigators have not announced a direct causal connection between the two cases.

Defense Cites Alleged Psychotic Episode

Walsh’s attorney, Andrea Lyon, has said her client was experiencing what the defense described as a “psychotic episode” at the time. That characterization comes from Walsh’s attorney and has not been established as a finding by a court.

The Illinois Department of Children and Family Services told news organizations it had no record of prior contact with the family before the Sept. 1 incident.

Walsh was transferred to the Will County Adult Detention Facility after receiving medical treatment. She was scheduled to appear in court Sept. 8. As of publication, IRC Media had not confirmed an outcome from that hearing.

IRC Media will update this story as additional information from the court proceeding or investigators becomes available.

Corie Walsh is accused of a crime and is presumed innocent unless and until proven guilty in a court of law.
