SCHAUMBURG, Ill. – An Illinois mother will find out her fate after she admitted to killing her disabled adult daughter.

Attorneys say Bonnie Liltz adopted Courtney when she was just an infant, adding that her severe disabilities made it difficult to find a family who was able to care for her.

Liltz says she bathed, changed, fed, dressed and loved Courtney, who was born with cerebral palsy, for 23 years, adding that every day was a privilege to be her mother.

“Bonnie’s world was Courtney,” Thomas Glasgow, Liltz’s defense attorney, told WBBM. “There was nobody else that mattered to her as much as Courtney did.”

While caring for Courtney, Liltz says she was also batting ovarian cancer.

At one point, Liltz says she had to put Courtney in a state-run facility because she could no longer care for her while she underwent cancer treatments.

She told WBBM that she found Courtney covered in drool, in need of a change and ignored by the staff at the facility.

Last year, Liltz learned that she had intestinal failure and thought it would likely kill her.

She told prosecutors that she couldn’t bear the thought of dying and leaving Courtney to be put back into a facility.

Instead, she gave Courtney and herself a mixture of drugs in an attempted murder-suicide.

Courtney died from the overdose, but Liltz survived.

She pleaded guilty to involuntary manslaughter and will now learn whether or not she will spend time in prison.
