UCLA Shooter Killed Estranged Wife Before Campus Incident: Police

— -- Mainak Sarkar, the man who shot and killed a UCLA professor Wednesday before turning the gun on himself, is also believed to have climbed through a window to kill his estranged wife in her Minnesota home prior to the UCLA incident, authorities said.

The Hennepin County Medical Examiner's identified a body found in an apartment in Brooklyn Park as 31-year-old Ashley Erin Hasti. The couple had been separated for some time, according to the Brooklyn Park Police Department. No previous calls to been placed relating to Hasti or Sarkar, police said.

Police responded to a welfare check at the apartment building Thursday morning and found Hasti dead from an apparent gunshot wound. The apartment had a broken window, and police believe that Sarkar climbed through it to gain access to the residence. Early indications are that the shooting occurred prior to the UCLA incident, police said.

Hasti had been studying to become a doctor, The Associated Press reported.

Sarkar's car was found Friday afternoon in Culver City, California, according to the LAPD.

Sarkar had a note on him when he died requesting that whoever found it check on his cat, police said. The note also listed the Minnesota address where Hasti's body was found.

After killing his wife, Sarkar then drove to Los Angeles, police said.

Professor of mechanical and aerospace engineering William Klug was killed by Sarkar on Wednesday. Klug was Sarkar's teacher, according to law enforcement officials, and the two had a long-standing poor relationship, the LAPD said. Police believe that Sarkar's grades may have been a factor in the killing.

Klug, who was married with two children, would coach soccer and Little League Baseball in his time away from the university, ABC-owned station KABC in Los Angeles reported after his death.
