Seventeen-year-old John Granat is facing first-degree murder charges in the deaths of his parents. He was denied bond Tuesday.
Cook County Sheriff Tom Dart says Granat told investigators he was home all night. But they later determined he'd been pulled over by police two hours before he called 911 to report finding his parents dead early Sunday in their Palos Park home.
The county medical examiner says 42-year-old Maria Granat and 44-year-old John Granat died after suffering multiple blunt force injuries.
Police haven't revealed a motive for the killings but say the teen had made past death threats against his parents.
