Witness in Jennifer Hudson family murder trial says defendant William Balfour spied on home

(CBS/AP) CHICAGO  - A witness in the trial of William Balfour, the man accused of killing three of actress-singer Jennifer Hudson's family members, says he saw the defendant spying on the Hudson family's home in the summer before the murders.

Reginald Jones testified Tuesday that in the summer of 2008, he was walking near the Hudson home when he was startled by William Balfour, who was sitting in the dark on the rear stairs underneath the bedroom window of his estranged wife, Julia King.

Balfour is accused of gunning down 29-year-old Jason Hudson, 57-year-old Darnell Donerson and 7-year-old Julian King on Oct. 24, 2008.

Under questioning by the defense, Jones said he would open the door to the Hudson home for customers seeking to buy drugs from Jason Hudson. He also said he helped prepare cocaine for sale.
