UCI spokesman Tom Vasich told the Los Angeles Times that Doan was a biological sciences major at UC Irvine from September 2017 to June 2019, but did not graduate.

Police have contacted him several times before. The last one happened in 2019 and was linked to “mental health issues”, the statement said.

Investigators are trying to determine the motive for the murder-suicide, police said.
