Authorities have identified the two people killed in an apparent murder-suicide on the campus of University of California-Irvine Tuesday as an elderly woman and her son.

According to Irvine Police, Andrew Nguyen Doan, 36, picked up his mother, 77-year-old Thao Thai Nguyen, and “threw her off the landing of a multi-story building.”

Doan then jumped to his death.

Doan was a former student at UCI and last attended the school in 2019, police said.

“IPD has record of contacting Doan multiple times in the past,” police said in a statement Wednesday evening. “The last call for service involving mental health concerns was in 2019.”

Officers first received calls about bodies found lying near 214 Pereira Drive (Social Science Plaza B) around 3:52 p.m. Tuesday.

The motive remains under investigation.
