What we know about the Minnesota shooter

We begin in Minneapolis, where several school children have been released from the hospital following yesterday's deadly shooting at the Annunciation Church. They were among 17 people injured when a shooter opened fire through the church's windows. An 8 and a 10-year-old were killed. As officials investigate a motive for the attack, CBS News has verified several videos posted online and taken down by the shooter. They detailed journal entries that described plans for an attack on children, expressed suicidal thoughts, and referenced other mass shootings. Minneapolis Police Chief Brian O'Hara says the shooter had not been on police radar, but they were fueled by hate. Unfortunately, this is a deranged individual who, like so many other mass shooters, has had an obsession with previous mass shootings that was looking to cause as much trauma and carnage as possible for their own personal notoriety. We have not been able to narrow down a specific motive in this case, but we have seen just countless pieces of evidence that indicate a whole wide variety of hate towards various individuals and various groups of people.

CBS News Senior Coordinating Producer for Crime and Public Safety Anna Schechter joins me now. Great to have you here. He just mentioned they still don't know a possible motive. Any new reporting on that? Well, we know that the shooter actually visited the church in the weeks prior to the attack and conducted surveillance, law enforcement tells my DPC colleagues. And so we know this was really targeted. And we'd already seen that very specific, detailed drawing of inside the church. And my sources are telling me they believe that that drawing was made during or immediate aftermath of that effort to case the place. So that's just in to CBS News. And we're learning a few more details. The shooter was working at a local cannabis dispenser up until mid-August and had left the job. There are employees that have been talking to local newspapers about the shooter's sort of demeanor an inference that something big was going to happen, but no details about it. So, still, police are not pinpointing a motive. So he was working up until mid-August, and he was alluding to the fact that something was going to happen, but they didn't notice anything enough to report it? Not enough to report to police. And police have told me that there was really nothing that would have caused them to step in and confiscate weapons. The shooter legally purchased a firearms license and used that license to purchase those three firearms and others. And this was all legal under Minnesota state law. I think a lot of people are going to be looking at those laws. Remember also, there is a red flag law in Minnesota. So family, law enforcement, lawyers could have petitioned a judge to take those weapons away. But what police are saying is that nothing rose to that level. Where do things stand now in terms of the investigation? What happens next? Well, family members, former colleagues, and associates are being interviewed today as we are speaking. Those interviews are underway. They have gone through much of the electronic devices already. There are still a couple of other devices that they haven't gained entry into, and that might happen in the future. But we're just one day into this, so there's still a lot more to do. They were very quick to say that the shooter acted completely alone. I'm really curious to see if that shifts.

All right, Anna, thank you so much. And they did just update that it's now up to 18 that were injured during the shooting. Thanks again.
