Think about what the job of the President of a university is.
Here is a good article on it:

“typical responsibilities include fundraising for the school, ensuring the budget is balanced and being the outward facing leader, voice and representative of the institution.”
The first and a critical item is fundraising.
That means maintaining a positive public image.
A shooting on campus is a disaster for any university’s public image.
The President’s job is to make it go away from the public eye as fast as possible.
A shooter that escapes or dies before a trial helps that.
A long ugly trial hurts it.
I'm thinking that queer Palestinian has already fled the country.
