and to vince velazquez, homicide detective, vince, what do you make of it? the d.a.' insisting it's not a homicide investigation. do you believe it? >> i do. that's not unusual, nancy. it's a death investigation until we can -- or they can establish, perhaps, motive and intent, it's not going to be a homicide. maybe manslaughter. all the evidence collecting, all that's going to be presented to the district attorney's office and the medical community and the medical experts are going to make a determination as to whether this doctor -- >> mr. velazquez, are you a jd, a lawyer, as well as a hostage negotiator? >> no, ma'am. >> then why would you believe that this is just a voluntary manslaughter charge, when obviously someone had shot him up in the neck? >> right. what i'm saying is in this state, we have felony murder. i'm not sure about california. if they have felony murder, of course it could be. >> well put, well put. vince velazquez joining us, i want to show you that video that many people believe is the inception of michael jackson's addiction to prescription pa

vince velazquez, think like a homicide detective since that's what you are.rms of this timeline, and, remember, he hasn't been charged with anything. he's cooperating, he says, with authorities. we're not trying to say anything about him. the timeline is a big question, mark. the chef said normally he would come down the stairs with two oxygen tanks at around 10:00 every morning. the morning michael jackson died he did not come down the stairs until a little bit after noon. he didn't call 911 until 12:22. now, if nothing was wrong, if nothing was untoward that morning, why wouldn't he have come down the stairs at 10:00? if he was upstairs and something was wrong, why didn't he call 911 at 10:00 instead of at 12:22? >> absolutely. this timeline is crucial and the fact this chef made this statement is going to be crucial. all those people in the house, security, are going to add to this fact. this doctor was really in a panic. he did not do what he was supposed to do. >> is it a panic or could investigators be looking at the possibility, richard herman, bradfor
