when you hear about the wigs, the extra ammo and the items in the car, to you, does it suggest a plan or randomness of the madness? >> it suggests he may have had a broader plan. a cold and calculated and planned attack. there may be certain elements of the crime we may never know. >> how do you then rationalize how he went from having a plan to killing himself? circumstances? >> it could be circumstances. let's face it. when he committed the crime, he didn't disguise himself. there were cameras at the site. they identified the suspect quickly. when was he going to disguise himself? there are certain elements that point to mental illness. >> why have all that extra ammo and not have it on him at the time of the murder? he had it in the car.
