Randal Quan, after leaving Cal Poly, became a lawyer and represented ex-officer Christopher Jordan Dorner in his 2009 appearance before the LAPD disciplinary board in which he lost his police job.
Los Angeles police believe Dorner targeted Quan's daughter, Monica, because be blames him, among others, for the loss of his job.
Quan retired from LAPD in 2002 and in October was hired as police chief at Cal Poly.
Quan was dismissed from the position six months later. He filed a lawsuit against the school on Jan. 15, 2004.
"Quan, the former Cal Poly Pomona campus police chief who was non-retained, filed this action complaining that he was terminated because he objected to hiring an African American female," according to minutes from a Trustees of the California State University meeting.
The lawsuit was settled for $32,000, said Dan Lee, spokesman for Cal Poly, and the suit was dismissed on June 20, 2005.
Lee said he could not speak in detail about Quan's time at the university.
"We want to extend our deepest sympathies to Randal Quan and his family at this difficult time," Lee said.
Monica Quan, 28, and her 27-year-old fiance Keith Lawrence were found shot to death in their car at a parking structure in Irvine Sunday night, Irvine police said.
An investigation into their deaths led officials to Dorner.
The triple homicide suspect referenced that in an on-line manifesto, where he claimed he was falsely accused in the investigation and won't stop going after the LAPD until his name is cleared.
