A former University of California, Irvine, student flung his elderly mother from a building on campus and then jumped to his own death in a murder-suicide, police have confirmed. Andrew Nguyen Doan, 36, grabbed his 77-year-old mother, Thao Nguyen, and “threw her” off a multistory campus building before leaping to his own death around 4pm, investigators said Wednesday. Though Doan’s motive remains unknown, police said they had interacted with the former UC Irvine student “multiple times in the past”.
The Irvine Police Department last dealt with him in regard to a “mental health concern” in 2019 while he was attending the school.
Doan was a biological sciences major at school from September 2017 to June 2019, UCI spokesman Tom Vasich told the Los Angeles Times.
He never graduated and no longer had an affiliation with the university.
Doan was admitted to a mental institution sometime in 2019 and sexually battered his roommate, an Orange County District Attorney’s Office spokesperson told the LA Times.

“(Doan) had demons,” Mr Bertin said. “It’s a horrible thing.”
Mr Bertin added that Ms Nguyen was known as a kind but withdrawn woman who was often seen gardening on her front lawn.
The neighbour said he had not seen Doan in some time, but didn’t recall ever seeing the mother and son argue.
According to the Irvine Police Department statement released on Tuesday, officers responded to 214 Pereira Drive after receiving 911 calls about “subjects on the ground outside a multi-story building”.

“The victim is Thao Thai Nguyen, 77, of Irvine. The suspect is Andrew Nguyen Doan, 36, of Irvine. Andrew Doan is the son of Thao Nguyen.”
It added: “The investigation has determined Doan picked up Nguyen and threw her off the landing of a multi-story building. Doan then jumped from the same landing to his death.”
