There was no hearing for Calvo to respond to the complaints. He was escorted off campus on April 8, several colleagues said.
A university spokeswoman said Calvo was "on leave at the time of his death," and declined to speak about "matters of personnel, which are not public."
Just days after his ouster, Calvo sent a message to a close friend.
"The letter mentioned Princeton and was very strange, very weird, and his friend felt the need to go to [Calvo's] apartment," a pal said.
Calvo's body was found with self-inflicted stab wounds.
Yeah, that's tolerance and caring for you.
