A fisherman discovered a body in the Des Plaines River behind Hollywood Casino in Joliet Saturday morning.
An autopsy found the woman pulled from the river Saturday, died from stab wounds, though she was not positively identified.
Police say evidence suggests it’s the body of Jeannie Parker.
She’s been missing since late March, when her 21-year-old son told police he stabbed her to death, and dumped her body in the Des Plaines river.
Charles McCullum is charged with murder.
A vigil for Parker was scheduled to be held at Bicentennial Park in Joliet Sunday evening.
