 The 52-year-old headed the university's Department of Hydrology and Atmospheric Sciences. Dervish, who's 48 years old, was in the master's degree program in atmospheric sciences. Police say he was banned from the school in January of 2022 and later expelled for ongoing issues with professors after receiving bad grades. Jurors deliberated for less than three hours May 21st before reaching a guilty verdict. During the trial, Dervish's attorney said his client was in the middle of a psychotic episode at the time of the shooting and urged jurors to consider a lesser charge that would have meant confinement in a psychiatric hospital.
