Prosecutors played a 3-minute-long surveillance video Tuesday afternoon that showed the defendant, William Balfour, getting out of a car at a gas station not far from where the murders occurred on Oct. 24, 2008. Balfour has said he wasn't in the area at the time.

Hudson rested her head on her knees for several minutes as the video played on a courtroom screen.

Balfour has pleaded not guilty. He is the ex-husband of Hudson's sister, Julia Hudson. Jennifer and Julia Hudson both testified Monday.
