Riley Fox, 3, was a Chicago-area girl who was abducted, sexually assaulted and murdered in 2004. Her father, Kevin, was charged with her death until DNA evidence cleared him. The real killer, a man named Scott Wayne Eby, was sentenced to life in prison last fall, the Chicago Tribune reports.
The FBI says it was led to Eby because his ex-girlfriend, Trisha Kiefer, told agents that he should be checked out. The bureau has paid her $10,000 and credited her tip with helping solve the case. But the Foxes, who offered a $100,000 reward have not, the Tribune reports.
Three weeks ago, their attorney, Kathleen Zellner, called Kiefer's tip vague and said she should have gone to authorities sooner.
"I do not think that the Foxes owe her anything, quite frankly," Zellner said at the time.
"We put out hundreds of posters on (Riley's slaying), and (Kiefer) lived right in town. She sat there while Kevin went to jail."
The Tribunes notes that, on Friday, the attorney said the Foxes were reconsidering whether a reward should be made.
