Given how few disgruntled students murder their professors, no it would not be the Occam's Razor conclusion that the murderer was a disgruntled student.
Such an incident at a random small college or small university would not make the national news. MIT is one of the few nationally known universities, so it did.
I'm not sure why "bitter grad student" isn't everyone's default assumption.
Low percentage of grad students
MIT grad students don't generally have classes, let alone finals
Which is not to say there are no bitter grad students or colleagues at MIT.
Which was gopher_space’s material point.
Final exams at MIT started yesterday and don't end until Friday https://registrar.mit.edu/classes-grades-evaluations/examina... so grades are mostly not yet available.
as if the police are waiting for the victim to finish grading the exams

Finals not being over might make the idea unlikely
They started yesterday. A student who is going to outright fail it will likely know immediately before the results are in.
