Pretty inept, whoever the perpetrator was….If they wanted to do more than scare people and make a big HuHu.
I still hope that whoever he or she is, they catch him and incarcerate him for a long time.
ETA: Apparently a suspect in Custody….and (and this is significant!) they used his cell phone to track him down. (For good or for bad, having a cell phone in your name destroys your privacy. Even a burner phone, once you take it home, can be linked to you. If it is co-located while turned on with your “normal” phone, it becomes linked to you, especially if you drive with both phones powered up. So don’t do illegal shit , and the authorities won’t have a reason to use your phone to track you)
