The mechanical and aerospace engineering professor shot and killed in the UCLA murder/suicide is described as “brilliant and kind.”

The professor, 39-year-old William S. Klug, was a father of two who earned his PhD “in mechanical engineering from Caltech in 2003.”

According to the Los Angeles Times, Alan Garfinkel, one of Klug’s fellow professors, said, “I am absolutely devastated. You cannot ask for a nicer, gentler, sweeter and more supportive guy than William Klug.”

Melissa Gibbons, one of Klug’s former doctoral students, recalled Klug pairing students together when he saw one struggling, as a way to help them keep their grades up. Gibbons remembered Klug asking her to tutor one student because “he didn’t want to see her fail.”

Gibbons said, “To care that much in an undergraduate class says a lot about his character.”

Klug was shot and killed Wednesday morning around 10:00 a.m. in “a small office” inside the engineering complex. The student, now identified as Mainak Sarkar, according to CBS Los Angelesthen shot and killed himself.

The Times reports that California “invoked” the UCLA shooting within hours of its occurrence to bolster its push for an expansion of gun control laws in the state. UCLA is already a gun-free campus.
