The FBI acknowledged Friday, authorities don't have a suspect in the shooting deaths of a Colorado woman and her son-in-law in Chicago.
The victims were the mother and husband of federal judge Joan Humphrey Lefkow.
The FBI also announced a $50,000 reward to try to shake loose information in the case.
Special Agent Robert Grant is in charge of the FBI's Chicago office. He says investigators are looking at all angles, not just white supremacist Matthew Hale and his followers.
The 33 year old Hale is facing sentencing next month for soliciting an FBI informant to kill Lefkow after she ruled against him in a trademark lawsuit.
