Lydia H. Sim was 21 and lived in Hayward, California. She was killed on April 2, 2012, in the mass shooting at Oikos University, a small Christian college in Oakland, which left seven people dead.

The shooter, One L. Goh, was a former student who had been expelled from the university’s nursing program. Investigators and reports tied his motives to grievances against the institution and its staff; he was arrested soon after and charged with seven counts of murder and three counts of attempted murder. The case included assessments of Goh’s mental competency; he was initially declared incompetent to stand trial and later found competent after treatment.

Family and community members held memorials and vigils for Lydia, who was remembered as bright and cheerful and missed by those who knew her. If anyone knew Lydia or has information about her life at Oikos University, please share what you remember.
