ILLINOIS – The husband of a Lindsay Clancy-obsessed mom accused of hanging their 2-year-old son supported her in court Thursday as she pleaded not guilty during a preliminary hearing in the harrowing case.

Corie Walsh – who allegedly left the lifeless body of her toddler, Barrett Walsh, dangling from a rafter before trying to kill herself on September 1 – appeared in bright red jail garb with her hair tied back.

Walsh, 40, was charged with first-degree murder after Barrett’s two older siblings found him with a rope around his neck and feet off the ground in the basement of the family’s home in Frankfort, a suburb about 30 miles southwest of Chicago, and ran to a neighbor’s house for help, according to court documents obtained by The Post.

The frantic neighbor called 911 and tried fruitlessly to perform CPR on the tot, who didn’t have a pulse and was cold to the touch. He was pronounced dead at the scene.

An autopsy later confirmed that Barrett – who was affectionately called “Bear” – died of “asphyxia due to ligature compression of the neck,” according to court records.

His mom — whom cops discovered fully clothed, soaking in a bathtub full of bloodied water at the house – tried to take her own life by slashing her wrists and thighs with a dull kitchen knife. 

Walsh allegedly confessed to killing the youngster, claiming he was the “anti-Christ” and “devil,” the documents state.
