LOS ANGELES —A gunman who killed his former university professor left a trail of evidence that led police to a second body on Thursday. <br /> <br />Mainak Sarkar, 38, entered professor William Klug’s fourth-floor office at UCLA’s engineering building on Wednesday armed with two semi-automatic pistols. <br /> <br />Sarkar shot Klug dead before turning the gun on himself, prompting a two-hour lockdown at the school. Responding police officers found a note at the scene left by Sarkar, leading officers to his home in Minnesota and asking someone to “check on his cat.” <br /> <br />Inside Sarkar’s home police found a “kill list” that named Klug, Sarkar’s wife Ashley Hasti — who was later found dead — and a second UCLA professor, who remains alive. The second professor was off campus at the time of the shooting, according to Reuters. <br /> <br />When officers saw Hasti’s name on the list, they went to her address and found her dead inside with an apparent gunshot wound. <br /> <br />Records confirm that Hasti was married to Sarkar in June 2011, but it’s unclear whether the two were still married at the time of her murder. <br /> <br />Los Angeles Police Chief Charlie Beck told CNN affiliate KTLA-TV that a dispute over intellectual property may be tied to the UCLA shooting. Sarkar believed that Klug had stolen computer code from him and given it to someone else, Reuters reported.
