correspondent jeanne meserve. what is the latest on the investigation? >> well we understand at this point in time that the suspect, jared loughner still is not cooperating with authorities. a law enforcement source says there's no indication that his parents are not cooperating, but cannot tell me to what extent they are. search warrants were executed last night at the home where loughner lived with his parents and also of a vehicle and i'm told that evidence collection at the scene has now been completed. they are, of course, looking for surveillance tapes. they have one from the supermarket where the shooting took place, in that apparently i'm told by law enforcement you see the suspect in the store, and there is this second individual that they are looking for, you see the picture there, he's described as a white male between 40 and 50 years old, he's wearing a dark blue jacket, blue jeans. they want to find this man. they want to talk to him. it is unclear at this point in time exactly what connection he might have to loughner but they want to find out at this point
