What Did Corie Walsh Do? Mom Killed Son After Becoming 'Invested' in Lindsay Clancy Trial
Will County Sheriff's Office

An Illinois mother charged with murdering her 2-year-old son had reportedly become “very invested” in Lindsay Clancy’s high-profile murder trial in the weeks before the killing — a case with disturbing parallels to her own alleged crime.

Corie Walsh was arrested on September 1, 2026, after her son, Barrett, was found hanging from a rafter in the basement of the family’s Frankfort, Illinois, home, according to the Frankfort Police Department. Walsh has been charged with three counts of first-degree murder and denied pretrial release. She has also retained one of Casey Anthony’s former defense attorneys to represent her.

Everything to know about Walsh’s alleged crime and her case, below.

Corie Walsh Killed Her Son While Her 2 Older Kids Were at School

Two of Walsh’s school-aged children were not home when the killing took place, but they returned around the time Barrett was found, according to a pre-trial release denial petition viewed by People. Walsh’s fourth child, an infant, was discovered unharmed inside the residence at the time of her arrest.

When officers arrived, a neighbor was already administering CPR to Barrett. The neighbor told police she had found the toddler hanging with “ligature around his neck and his feet were off the ground.” The boy was later pronounced dead at a hospital.

Walsh was found fully clothed in a bathtub full of “bloodied water.” She allegedly told officers that her son was the “devil” and the “Antichrist.”

The neighbor told authorities she had found Walsh “actively harming herself” and had taken a knife from her, throwing it into a sink. According to the neighbor, Walsh said “she was trying to kill herself.”

Corie Walsh Was ‘Actively Discussing’ Lindsay Clancy’s Trial Hours Before Killing

Witnesses told authorities that Walsh had become “very invested” in Clancy’s trial, in which the Massachusetts mother was accused of strangling her three young children in January 2023. Walsh was “actively discussing” Clancy’s case via text messages with friends up to three and a half hours before Barrett’s body was found, according to court documents obtained by WLS.

Hours before Barrett’s death was discovered, Walsh wrote in a group chat that she was “freaking out” because she believed Lindsay’s ex-husband, Patrick Clancy, was involved in their children’s deaths, according to claims made in court on September 8, 2026, per NBC Chicago.

Walsh’s message aligned with conspiracy theories that Patrick was responsible for the killings — claims he has publicly denounced. Patrick has threatened legal action against those spreading the theories.

The Clancy trial was in the jury deliberation stage when Walsh killed her son. A Massachusetts judge declared a mistrial on September 4, 2026, after the jury was unable to reach a unanimous verdict.

Prosecutors have not revealed whether they will retry Clancy.

Corie Walsh Allegedly Threatened Her Other Children and Husband

Prosecutors have asked for Walsh to remain detained pending trial, arguing she made statements about harming her other three children, WLS reported, citing court documents. Walsh also allegedly intended to harm her husband, who was out of state at the time of the killing, once he returned home.

Corie Walsh Has Retained One of Casey Anthony’s Attorneys

During a court appearance on September 8, 2026, Walsh was denied pretrial release, WLS reported. Andrea Lyon, a Chicago-based attorney who served on Anthony’s defense team during her 2011 high-profile murder trial, is representing Walsh, NBC 5 Chicago reported.

Anthony was previously found not guilty of murder, manslaughter and child abuse in connection with the death of her 2-year-old daughter, Caylee. The Anthony case is described by A&E as “one of the most polarizing trials in United States history” that “continues to divide public opinion and raise questions about the complexities of justice and the role of the media in high-profile criminal cases.”

Lyon has argued Walsh was experiencing a “psychotic episode” when Barrett was killed.

“This is a tragedy for the Walsh family, all of whom are mourning the loss of this child,” Lyon said in a statement to ABC News. “It is also a tragedy in that Corie herself was experiencing a psychotic episode at the time this happened. It is our hope that through a thorough presentation and investigation of the facts, that all of us will come to see this heartbreak for what it is.”

Another attorney for Walsh, Robert Kerr, told a judge that the defendant had been “severely mentally ill” and suffering from a “brief psychotic disorder” when she killed Barrett, per NBC Chicago. Kerr added that she needs treatment. Court records indicate Walsh has not yet entered a plea.

She is being held in the Will County Jail, where she is to receive psychiatric care ahead of trial.

The Lindsay Clancy Case That Reportedly Consumed Corie Walsh

Clancy was arrested in January 2023 for strangling her three children, Cora, 5, Dawson, 3, and Callan, 8 months. She later leapt from a second-story window in an apparent suicide attempt, which left her paralyzed from the waist down.

Clancy pleaded not guilty by reason of insanity to three counts of first-degree murder. During her trial, which began in July 2026, her defense argued that she suffered from postpartum psychosis when she killed her children and had no sense of control over her actions. The prosecution argued that the murders were premeditated and that Clancy acted intentionally.

The mistrial was declared due to a deadlocked 11-1 jury.
