Chicago police said there is new evidence suggesting more than one person may have been involved in the killings of members of actress Jennifer Hudson's family. Primary suspect William Balfour is being held on parole after being arrested and questioned over the weekend about any conflicts he may have had with estranged wife Julia Hudson. Police are trying to determine whether or not another person drove Balfour to the West Side after the killings took place. Security video showed an unidentified person parking the family's SUV at a South Side high school at 12:30 PM on Friday. Meanwhile, cell phone records place Balfour on the West Side at the same hour. If this new information is accurate, it could indicate an accomplice to the murders. Detectives are working tirelessly to find out what really happened in this horrible tragedy.
