A Minnesota mom who was just awarded custody of her 6-year-old son was arrested for allegedly killing him and stuffing his body in the trunk of her car.

Cops found Eli Hart’s body in the trunk of his mom’s Chevy Impala when they made a traffic stop in Mound, Minnesota on Friday morning, according to ABC 5 Eyewitness News

Julissa Thaler, 28, was arrested after police noticed blood on the interior of her car and searched the car.

Eli’s father, Tory Hart, made numerous complaints about Thaler’s drug and mental health problems but was ignored by the courts, the report said.

Despite the complaints, Thaler was awarded full parental custody just 10 days before his body was discovered.

Tory Hart’s fiancé Josie Josephson told Fox9 that the court failed Eli by handing the boy to his mother despite her mental health and substance abuse issues.

“No matter how many cries we cried, they ignored us,” Josephson said. “No matter how many warning signs there were.”
