[NOTE: To be technical, Crooks is a murderer but only an attempted assassin. I haven’t seen a thing explaining where his victims at the rally were seated at the time they were hit, or the order of the shots. I assume we’ll find out in a while, but I wonder how much correct information we’ll ever get on this.]
Here’s the first article I’ve seen that attempts to track Crooks’ movements for the 24 hours prior to the shootings. It’s about what one would expect:
On Friday, Thomas Matthew Crooks visited the Clairton Sportsmen’s Club and practiced firing shots, a law enforcement official told CNN. …
Crooks’ father, Matthew Crooks, was also a member of the club, and the pair enjoyed going shooting there together, law enforcement said.
The club’s rifle range is about 200 yards long …
On Saturday morning, Crooks bought 50 rounds of ammunition at Allegheny Arms and Gun Works in Bethel Park. …
After his stop at the gun shop, Crooks went to a Home Depot, where he purchased a five-foot ladder. A receipt for the ladder was later found in his pocket. …
He used an AR-style rifle that was registered to his father. The weapon — as well as the over 20 other guns registered to Matthew Crooks — was purchased legally.
Investigators found an explosive device in Crooks’ car and a transmitter on his body, suggesting that he may have intended to stage a distraction during the shooting.
Crooks’ parents seem rather clueless about this – which makes sense if Crooks was the sort of quiet person who kept his mouth shut about what might be going on inside him, but apparently showed few signs of disturbance except social isolation.
As for motive, I don’t think it’s so puzzling at all. The motive was most likely notoriety. Crooks seems to have been a total nonentity, smart but making little to no mark on the world or anyone in it. Trump is probably the world’s most famous person. Whether Crooks hated Trump or not will never be known, although it’s probable that he did. But even without such hatred, the desire to go down in history as a mastermind assassin would be plenty enough motive to do this and to be willing to die in the attempt.
