Now back to the search for clues in many of them police say are gone for killer at a -- embarked -- his vicious killing spree he destroyed his computer hard drive.

But what clues might be on that hard drive LAPD detective mark -- joins us I'm not if you're asked about the hard drive -- curious.

In in -- -- investigation at this point what do we need to know and why we know what did it.

And what he's dead.

And there's no suspicion that there is a co conspirator out there are that he and help and yet you know we are obsessively going after this why.

Well Greta what do you you have to do it induces a matter of protocol you -- to match up all the ballistics for every bullet that's comparable to that firearm.

You have to do that you have to -- friends exit toxicology on the shooter make sure that the shooters gun was it was actually the gun that was used to kill himself you have to put all these pieces of the puzzle together.

Because you really don't know where this is gonna go you don't know if somebody -- actually.

Been in contact with -- Adam -- and actually gave him the idea or was -- chat room and really.

The kind of prodded him into this crime -- you don't know where it's going and I think that's why they're so aggressive.

What could possibly be on the hard drive why -- look at the hard drive.

Is certainly he's trying to hide something perhaps he's trying to hide that his mother was gonna have him committed and he founded on the computer somewhere.

Are perhaps he has been contacting people or he actually.

Went on to web sites that he doesn't want anybody to think that he did this.

That he planned this or or anything else but there's obviously something on that computer hard drive that in his mind.

Was so important to destroy before he left to go to the school.

The thing that I want to know as I want to know about -- Thursday Wednesday Tuesday and Monday that's what I wanna know where was he who did talk into what was he doing.

Well I think that's one where you're gonna find out who sit at home a lot of zoning communication -- a cell phone and a computer so.

That's two avenues that they did you have the -- on information by now on the probably have a lot of information from the computer a web server web browser.

But.

I would agree with you what is he doing that during this time -- is he going to see is the acquiring ammunition.

Additional magazines is he getting a tactical vest is he doing things.

To supply of the crime or was this all spontaneously kill -- mom during an act of rage.

And then after he did this realizing that he's going to go out and in a flame of glory or.

And mortality or however his twisted mind would think it to -- I agree with you I would like to know what happened.

The days prior to this.

-- -- -- -- Thank you.
