The UCLA gunman's wife was found dead in her Minnesota home hours after her husband fatally shot his former professor in Los Angeles and then killed himself.

Ashley Hasti, 31, died of a gunshot wound to the head, almost certainly at the hands of Mainak Sarkar, who listed her on his 'kill list'.

St Paul-based PhD graduate Sarkar had been planning to execute more victims after killing professor William Klug in the UCLA engineering building on Wednesday - but killed himself instead, the LAPD revealed on Thursday.

UCLA graduate Sarkar, 38, who was born in India before coming to the US to study, is suspected of shooting Hasti in her home near Minneapolis several days ago before driving to southern California.

She was discovered by officers at around 12.30am carrying out a welfare check on behalf of the LAPD. Multiple sources confirmed that she married Sarkar in 2011.

Police say they found a 'kill list' at Sarkar's home, also near Minneapolis, which included the names of his former PhD supervisor Klug and the female victim, alongside that of another UCLA professor who used to teach Sarkar.

Detectives say Sarkar likely intended to kill that professor as well, but may have been unable to find him because he was not on campus.

Mainak Sarkar, 38, who shot and killed UCLA professor William Klug, 39, on campus Wednesday, murdered Ashley Hasti (pictured together on his Facebook page) at her home in Minnesota before driving to find his former instructor. The pair got married in 2011

Police say they found a 'kill list' inside Sarkar's home that included Klug's name, the name of the female victim (named locally as Hasti, pictured), and the name of another professor who used to teach him at UCLA who escaped unharmed

Police said Sarkar may have targeted Klug, a married father-of-two, in a dispute over a piece of code he wrote while he was a student. Cops said the other professor named on his kill list was involved in the same dispute

LAPD chief Charlie Beck said that Sarkar was involved in a long-running dispute with both professors because he believed they had stolen computer codes he wrote as part of his PhD before passing them on to another student.

However, Beck added that there is no evidence to suggest this was true, saying the slight was a figment of Sarkar's imagination. Beck refused to confirm Hasti's identity, and would also not discuss sarkar's motive for killing her or the nature of their relationship.

At the time of her death, Hasti was enrolled in the University of Minnesota Medical School, a university spokesman said. She first enrolled in the college in 2012. In 2008, she received a bachelor's degree in Asian languages and literature from the same institution.

Ashley Hasti's grieving family were too upset to speak on Thursday night as they emerged from the Minneapolis home where it is believed she was shot to death by her unhinged ex-husband, Mainak Sarkar.

Medical student Ashley's distraught sister Alex was one of three relations that declined to speak as they climbed into a car and drove away.

In the neighboring city of St Paul's, Minnesota, former neighbors at the suburban apartment complex where Sarkar had rented a third-floor studio for the past two years, described him as secretive and argumentative.

'He was a total p****head,' said Todd Sorensen, who lived directly underneath. 'He would make all this noise at three or four in the morning. It sounded like he was hammering away or knocking things over. '

And yet he was the first to complain when it came to others. He complained about my smoking several times and the last time he knocked on the door, I told him to get lost.

'The management got involved and that was the last time I ever spoke to him. I saw his cat though, a little grey thing. It was scared crapless of people.'

Mr Sorensen said he was woken in the early hours of Thursday when police and bomb disposal specialists stormed the building, comprising 11 studio apartments with adjoining bathrooms and kitchens.

'I heard movement and people stomping around,' he said. 'They searched his apartment and it sounded like they tore the place apart.

'They told me and another lady to leave and they searched our rooms as well. They took something outside and next thing there was a loud boom. I think they just detonated whatever it was, just to be safe. 'There were cops everywhere. It was like a weird dream - I thought I was hallucinating'

Klug was described as both intellectually brilliant and kind by friends and colleagues who paid tribute to him Wednesday, saying he loved baseball and coached his son's little-league team

Police say the remains of an adult female, thought to be Hasti, were found inside this property in Brooklyn Park, close to Minneapolis, Minnesota, at 12.30am and may have been there for a couple of days

Sarkar was said to be living in this apartment in Minneapolis. His neighbors said he would rarely acknowledge them and would constantly receive UPS and FedEx packages

A sign reading 'Studio Apartment Available' is set up outside Sarkar's last known address. A bomb squad is believed to have carried out a controlled detonation at the property on Thursday morning after the shooting

Another neighbor who asked not to be named added: 'He woke at 5am and took a shower every morning, just like clockwork. He never said hello all the times I passed him in the hallway. He would get all these packages from UPS and FedEx. He was a mysterious guy but he kept himself to himself.'

Describing Wednesday's events, the LAPD's Beck said that Sarkar had traveled to Los Angeles 'some time in the last couple of days', raising the prospect that Hasti's body had lain undiscovered for some time before officers found it.

Mark Bruley, a spokesman for the Brooklyn Park Police Department, confirmed that the shooting in Minnesota happened before the killing at UCLA, but said he could not reveal the time difference between the two.

Beck added that officers are checking on Sarkar's family members and loved ones out of 'an abundance of caution' to see if there are other victims, but said they are not expecting to find any more.

Sarkar was armed with two 9mm semi-automatic pistols when he arrived at UCLA, Beck added, saying at least one was purchased legally in Minnesota. He also had several fully loaded magazines and additional loose ammunition.

Beck said: 'This is a tragedy, but if there is a silver lining here, it's that Sarkar could have done a lot more damage with the ordinance that he brought.'

Beck also revealed that detectives were led to Sarkar's home by a note he left at the scene of the UCLA shooting asking whoever found his body to go and check on his cat.

Officers are also searching for a grey Nissan Sentra, with Minnesota licence plate 720 KTW, that Sarkar is believed to have used to drive from Minnesota to LA, saying there may be valuable evidence inside.

In a blog post uploaded on March 10 under Sarkar's name, he writes that Klug 'stole all my code and gave it another student', branding him a 'sick man'.

The post, which was uploaded to a blog called Long Dark Tunnel but has since been deleted, says: 'William Klug, UCLA professor is not the kind of person when you think of a professor. He is a very sick person. I urge every new student coming to UCLA to stay away from this guy.

'My name is Mainak Sarkar. I was this guy's PhD student. We had personal differences. He cleverly stole all my code and gave it another student. He made me really sick.

'Your enemy is your enemy. But your friend can do a lot more harm. Be careful about whom you trust. Stay away from this sick guy.'

Beck said that while Klug and his colleagues were aware of Sarkar's issues with the property rights, and thought of his behavior as odd, they did not view him as a threat.

Klug was found shot dead inside this office at UCLA Wednesday alongside Sarkar's body, a 9mm pistol, and a note from the PhD graduate asking whoever found his remains to go and check on his cat

Students were back on campus Thursday a day after being placed on lockdown for two hours following the shooting

A source told the LA Times that Sarkar's claims were 'psychotic', adding that his characterization of Klug as a thief is 'absolutely untrue'.

Klug was dedicated to helping Sarkar pass the course, the source added, saying he bent over backwards to help even though the quality of Sarkar's work was often below par.

Klug's widow Mary Elise Klug said in a statement released by the UCLA that the death of her husband was an 'indescribable loss'.

'During this extremely difficult time for our family, we are grateful for the tremendous outpouring of support,' she said.

'This is an indescribable loss. Bill was so much more than my soulmate. I will miss him every day for the rest of my life. Knowing that so many others share our family's sorrow has provided a measure of comfort.'

A UCLA spokesman told Dailymail.com that Sarkar earned his PhD in the summer of 2013, the same year he submitted his dissertation thanking Klug for his help in putting it together.

His dissertation and thesis, which he compelted in 2013, was approved by Klug. Sarkar dedicated it to his late mother, Ira Sarkar.

The shooter's social media profiles show he obtained his undergraduate degree in aerospace engineering from the Indian Institute of Technology, in Kharagpur, in 2000. The prestigious institution is known as the MIT of India, and alumni include current Google CEO Sundar Pichai.

He then worked for a time as a software developer in Bangalore before moving to America, where he worked as a research assistant at the University of Texas in Arlington.

In 2003 he went to Stanford to study for a Masters in aeronautics and astronautics, graduating two years later, and then going back to work as a software developer in Texas.

It was after that job that he began studying for his PhD in mechanical engineering at UCLA, working as a teaching assistant for a few years, and then taking a job at Endurica, a rubber testing company where he specialized in 'elastomer fatigue'.

However, an email from Endurica to the Dailymail.com revealed that Sarkar stopped working for that company back in 2014. It is not clear what, if any, employment he had in the last two years.

A UCLA spokesman said the institution is trying to establish whether Sarkar worked for them after he graduated, and whether he had any other connections to the college.

Klug, an associate professor of mechanical and aerospace engineering at UCLA, was married with two young children and spent his spare time coaching his son's little-league baseball team, friends said.

Co-workers praised Klug as both brilliant and kind, a rare blend in the competitive world of academic research, according to the LA Times.

Hundreds of armed officers responded to the shooting, searching classrooms one by one and eventually discovering two bodies inside a small office alongside a 9mm semi-automatic pistol and what is believed to be a suicide note

Thousands of panicked students were ordered to shelter in place and barricade themselves in classrooms after the shooting, and remained there for around two hours until police declared the area safe

The campus was declared safe around two hours after the shooting was first reported, though armed officers remained for a short time to conduct final searches

Officers checked each person to come out of the building for any weapons to ensure a second shooter was not hiding among them

Hundreds of students who were earlier preparing for finals were forced to shelter and were then evacuated by police

Alan Garfinkel, a fellow professor and one-time collaborator with Klug, said: 'I am absolutely devastated. You cannot ask for a nicer, gentler, sweeter and more supportive guy than William Klug.'

California Lt. Gov. Gavin Newsom described him in a tweet as an 'empathetic, brilliant teacher'.

Melissa Gibbons, one of Klug's former Ph.D students, said he was an exceptional mentor and always tried to help out struggling students, once asking her to mentor an undergraduate who he felt needed extra instruction.

Chancellor Gene Block said: 'Our hearts are heavy this evening as our campus family mourns the sudden and tragic deaths of two people on our campus.'

Around 200 armed police, SWAT officers, FBI agents and firefighters were called to the campus to reports of at least three shots fired inside the Engineering IV building at around 10am on Wednesday, before finding the bodies of both men alongside a 9mm semi-automatic pistol.

Images taken from inside a classroom purport to show the shooter walking through the college campus.

Thousands of students revising for finals were ordered to shelter in place and barricaded themselves into classrooms for around two hours before the campus was declared safe.

According to a website set up in tribute, Klug's areas of interest included computational structural and solid mechanics, computational biomechanics, and micro/nanomechanics of biological systems.

He is said to have graduated from California Institute of Technology - Caltech in 2003.

UCLA staff and students were forced to use their belts to lock doors during Wednesday's shooting, with many complaining that doors were difficult to secure because they opened outward, prompting a review of safety on campus .

Images showed others tying computer cables to the inside of door handles using large printers as ballast, while others used projectors, tables and chairs as makeshift barricades.

Olivia Cabadas, a 22-year-old nursing student, was getting ready to take a quiz in the mathematics building when her classmates began getting cellphone alerts. Through a window, they could see students rushing down the hallway. An officer then yelled that everyone should get out.

'It was just a little surreal - this is actually happening,' Cabadas said. 'It was chaos.'

Students were ordered into lockdown and told to barricade themselves in place while armed officers searched for a possible shooter, though it has since been revealed that the killing was a murder-suicide

Students and staff who were busy preparing for final exams had to be evacuated from study rooms. They were pictured being marshaled away from the scene with their hands over their heads

UCLA police were the first to respond to the shooting, followed by the LAPD along with SWAT teams and FBI agents

Students on lockdown posted images of themselves inside classrooms, including one student who sealed a doorway by tying a belt around the opening mechanism

Umar Rehman, 21, was in a math sciences classroom adjacent to the building where the shooting took place. The buildings are connected by walkway bridges near the center of the 419-acre campus.

'We kept our eye on the door. We knew that somebody eventually could come,' he said.

The door would not lock and those in the room devised a plan to hold it closed using a belt and crowbar, and demand ID from anyone who tried to get in.

Scott Waugh, an executive vice chancellor and provost, said the university would look into concerns about doors that would not lock. Overall, he said, the response was smooth.

Jason La, 33, a computer science graduate student, told the LA Times that he was sitting in Boelter Hall taking a test about 9:40 a.m. when an officer walked in and told the class to lock the door and barricade it.

About a minute later, they were told to leave. As students began to move out of the building, an officer yelled at people to get away from the building and people began to run away, La said.

On Wednesday afternoon, Los Angeles Mayor Eric Garcetti issued a statement on the UCLA shooting.

He said: 'My thoughts and prayers go out to all those affected by what appears to have been a murder-suicide on the campus of UCLA.

'This horrific event, at an institution dedicated to learning and mutual understanding, reminds us once again of the fragility of a peaceful society.

'Thankfully, the campus is now safe — but I am heartbroken by the sight of SWAT teams running down avenues normally filled with students, and angered by the fear that one person with a firearm can inflict on a community.

'I want to commend the entire UCLA community for its extraordinary grace and calm on a traumatic morning.'

Rafi Sands, vice president of UCLA's student government, said he and about 30 other students used their belts to secure their classroom door after news of the shooter spread.

The school on the west side of Los Angeles is a flagship of the University of California system, with about 43,000 students. It's currently the week before final exams. Vehicles were also being directed away from the campus.

At a news conference, UCLA Executive Vice Chancellor and Provost Scott Waugh characterized the events as 'tragic' and provided updates about how the shooting would affect campus operations.

'I want to say that our hearts go out to the victims,' Waugh said. He said also that while classes and evening events were canceled for the day, commencement and final examinations will continue as scheduled.

'We want to resume normal operations as quickly as possible, so we will resume scheduled classes tomorrow morning,' he said. 'Faculty, staff and students should show up tomorrow and go through their regular routines and complete the quarter as planned.'

Waugh praised local law enforcement for its cooperation and rapid response.

WILL AND GRACE STAR DEBRA MESSING DRAWS IRE ON TWITTER WITH 'GUN SAFETY SELFIE' IN WAKE OF UCLA SHOOTING Will and Grace star Debra Messing has come under fire after posting a selfie that was meant to bring awareness to gun violence in America amid news of the UCLA campus shooting. As news broke about the tragic murder-suicide at UCLA's engineering school on Wednesday, Messing shared a photo of her wearing shirt that read 'Under the Gun,' the title of Katie Couric's new gun violence documentary. The 47-year-old's now-deleted tweet also included the caption: 'HORRENDOUS Watching news about shooting at UCLA with casualties while taking selfie 2bring awareness to Gun Violence.' Twitter users quickly hit out at the actress, criticizing her for posting the selfie with some calling her a 'narcissistic, self-absorbed celebrity,' according to the New York Daily News. 'Ima talk about the senselessness of gun tragedies, but 1st a pensive airbrushed selfie to convey the seriousnes of it~shorter @DebraMessing,' user LMR wrote. 'People dying...better take a selfie!' another user, Lazarus Stalker, wrote. 'You didn't think this through did you,' Twitter user suburban dad tweeted at The Mysteries of Laura actress. Messing deleted the tweet after she was faced with backlash and apologized as she wrote 'Take a stand. This day was predetermined as a day of awareness. Don't belittle the effort. #wecandobetter' She then posted several tweets explaining she had shared the selfie as part of the pre-planned day of advocacy meant to bring awareness to gun violence in America. We were all asked to a post a picture wearing this t-shirt. AS I took the picture, the news broke about the shooting at UCLA,' Messing wrote. 'I was so shocked and struck by the horrible IRONY that yet another shooting was occurring as I was participating in this effort. 'In an effort to highlight the irony, I posted a picture referencing the breaking news.' Advertisement

Pupils were filmed streaming out of locked buildings and back to residences after classes were cancelled for the remainder of the day

'I also want to thank all the law enforcement agencies of Southern California who reacted so quickly to help secure the scene and help us prevent further damage to the campus,' Waugh said. 'The lockdown went extremely smoothly. That was the result of the efficiency of the BruinAlert system, which enabled people to know what to do in a timely fashion.'

In the wake of the tragedy, UCLA officials will continue to examine all campus procedures related to an active shooting, he said.

'We've gone through many scenarios in the past and we'll continue to do that,' Waugh said. 'We'll learn from this event and we'll learn how we need to work as cooperatively as possible with the different law enforcement agencies to make sure that we can handle these kinds of situations effectively and safely for the students, faculty and staff.'

There were reports however that some professors were ignoring warnings by the UCLA administration to cancel exams, and told students to find computers to complete them.

UCLA is in the Westwood section of Los Angeles and one of the more well-regarded schools in the University of California system, known for its successful sports program.

'I couldn't believe it happened at UCLA,' said Sam Zheng, 38, a researcher who was working in the engineering building at the time of the shooting. 'I just want to go home. I don't want to stay here.'

Engineering student Aaron Feigelman said he received a text message alerting him to an emergency and entered an adjacent building, where he and five others took refuge for 90 minutes.
