Whitney Wilde is out front live from Madison, Wisconsin.

And Whitney, I know you were just in mass press conference.

You were the one who got the information about the shooter's parents right now being in an interview with police.

What more are you learning?

Well, Aaron, there are still many details left to learn.

But what we know at this point is that this teenager, according to law enforcement, source was a female, a 17-year-old who died of a self-inflicted gunshot wound.

As you mentioned, police are interviewing the parents as we speak.

That is absolutely critical as they tried to figure out what the motive was here, Aaron.

At this point, Chief Sean Barnes, the chief of the

Madison Police Department, could not describe in detail the motive. I asked if the parents

are supplying that information. He was reluctant to say that they were because the most important

thing he says in an interview like that is to just let the parents talk and keep that conversation free flowing.

The critical details, Erin, that we did learn at this press conference for the first time all day

is what kind of security protocols that school has in place.

And it's really a lesson for schools even beyond Madison because the representative of the school here

said that they took advantage of Department of Justice safety grants to help them beef up their security.

And as part of that, Aaron, they were able to upload blueprints of their school.

And so when police arrived, they were able to download those blueprints of the school immediately, which significantly helps a police response. We know that police response was immediate,

Aaron. It was within three minutes. That call came in at 10.57 a.m. Police were inside that building

by 11 a.m. Law enforcement did not fire any shots, according to police. Again, there's a law

enforcement source saying that that suspect died the self-inflicted

gunshot ruined Aaron.
