2. Local authorities say Robinson is NOT cooperating with the investigation.

3. Robinson was able to escape the scene, and was only caught after being recognized from the images the FBI circulated. Several people had a hand in turning him in, including . . . his father, his roommate, and the family's pastor.

4. There's no motive for the assassination yet, but one might come to light. There's talk that the authorities have some kind of "note" that was written by Robinson . . . but they haven't released any specifics, so it's unclear if it's something incriminating, some kind of manifesto, or what.

Of course, there's a chance that Robinson cooperates, and provides a motive.

5. Robinson's family says that a while back, Tyler did mention that Kirk was coming to Utah over dinner. Tyler shared some strong feelings about him, calling Kirk "full of hate and spreading hate."

6. It sounds like the Robinson family is almost entirely Republican. Tyler was registered to vote, but does not have a party affiliation, and is listed as inactive, meaning he hasn't voted, including in last year's presidential election.

7. Robinson's family says that he had become increasingly political in recent years, although there aren't any specifics on what drove that.

8. Officials say there are signs that he had been "radicalized" but there are conflicting reports about what those intense feelings may have come from.
