SCHAUMBURG, Ill. — A Schaumburg woman is accused of forcing her severely disabled daughter to take a lethal combination of drugs.
Authorities found 55-year-old Bonnie Liltz, and her 28-year-old adopted daughter, Courtney, unresponsive in their beds in the 1100 block of S. Springinsguth Road on May 27, police said.
“The subsequent investigation indicated Bonnie attempted to end Courtney’s life and commit suicide with this cocktail of various over the counter and prescription medication,” said Schaumburg Police Lt. Shawn Green.
Both were taken to Alexian Brothers Medical Center in Elk Grove village. Bonnie later regained consciousness. Courtney never did.
The Cook County Medical Examiner declared Courtney brain dead on June 1.
She was removed from life support and died early Friday morning.
Bonnie Liltz is now charged with first degree murder. A judge set bond at $100,000.
