Los Angeles police have identified the man they say carried out a murder-suicide on the UCLA campus.
A police spokeswoman, Officer Jenny Houser, says the gunman was Mainak Sarkar.
Sarkar gunned down mechanical engineering professor William Klug in an office Wednesday before taking his own life.
The shooting triggered a huge police response until authorities determined there was no continuing threat.
Classes are resuming Thursday except for the engineering department, which will reopen next week.
