Copypasta from a 2A forum I belong to. This is a first hand account…
"I was just driving home and was passed by a bunch of UHP troopers that pulled over a bus that looked like a greyhound but it could have been an airport shuttle bus. Since we were northbound on I-215 an airport shuttle seems possible.
About a dozen UHP cars decended on it, looked like they got the driver off first then unloaded all of the passengers before leading away one guy in cuffs.
I was near the front of the stopped traffic and the whole thing only took about 15 minutes. Not sure if he is connected but this much of a police response this soon afterward, I suspect a connection to the shooting. Sorry for the potato pics, I don't think my lens was very clean and this was about 8x zoomed in."
