Two children living with the Lindsay Clancy-obsessed mom accused of hanging her 2-year-old came home from school to discover a horror, prosecutors claimed.

Corie Walsh, 40, was held without bail by a judge Tuesday during a hearing in the case accusing her of fatally hanging her son, Barrett.

Prosecutors claimed at that hearing that two kids returned home as the horrific situation was underway and ran to a neighbor’s house to get help, according to a report by NBC 5 Chicago.

The neighbor pulled Barrett down from the rafter he was hanging from and began to perform CPR — but was unable to revive the little boy.

Then the adult found Walsh in the bathroom as she was actively trying to harm herself.

Walsh allegedly also said she wanted to poison her husband, prosecutors claim.

Her lawyers have claimed she was in the throes of a psychotic break and can’t be held criminally responsible.
