A Chicago mother who allegedly believed her three children were “possessed by the devil” tried murdering them — killing one, age 4, after plunging a knife into the boy’s chest — before setting the family’s house on fire, local officials say.

Wendy Tolbert, 45, is accused of fatally stabbing her 4-year-old son, Jordan Wallace, on Friday morning at their home in Chicago’s Logan Square neighborhood, according to local NBC affiliate WMAQ.

Prosecutors revealed details about the morning attack in court Sunday as Tolbert appeared on murder, attempted murder, arson and other charges.

According to WMAQ, Tolbert allegedly targeted her 10-year-old son first while he was playing video games with the 4-year-old victim, stabbing him in the right arm, prosecutors said. She allegedly set her sights on the 4-year-old next and stabbed him more than three dozen times before going after her 13-year-old daughter as she tried to call police and escape, per prosecutors.

After allegedly attacking her three children, cops say Tolbert sparked a blaze and went outside. Police and firefighters reported finding the kids inside the residence after receiving reports about the fire and responding.

“I got this child yelling for help out the basement window,” an officer could be heard saying in an emergency response call, according to ABC affiliate WLS. “We’re trying to get her out of the window. I do see blood.”
