The most likely suspect I can think of would be a disgruntled student or former student or, because the professor was a Portuguese national, it’s some deranged MAGA who thinks they are doing Trump’s bidding.

due to the suspect in the Brown University shooting within driving distance in Providence still on the loose.

Both shootings targeted Engineering and Physics.

Too much of a coincidence? Settling scores?

This is insane but don't worry, the 6 fetid piles of sh7t on the SC will make sure all guns are safe.

as was the prof who’s classroom was shot up at brown. she wasnt there, but…

1) The choice of specific classroom seems arbitrary at Brown. Seems like it was the first one he came across.
2) Whether the classroom used for the final review was the same classroom usually used for the class is unknown.
