a tactical strike they went into a home. it is unclear as to why they were looking at that home, why they were targeting that home, but then we understand a forensic team went in following that. they were looking there. a couple of hours later, right on the street, just in front of me, and here is what we're seeing all day, anderson. i'm sure a lot of people are, but you're seeing sort of heavy artillery vehicles. this actually may be a shift change. and that's going to work in the favor of law enforcement. because you have to remember, this 19-year-old kid, he is -- he may be finding a place to sleep, but he's been up for an awfully long time. he witnessed the death of his brother. and now he is on his own. he's on his own. and he is, as far as we know, isolated, though it does appear that he isn't reaching out to the outside by some sort of device or some sort of internet device. unclear there. but things are slowing down. there have been a shift change. and what we're being told is that law enforcement still gearing up for what could be a very long night.
