Brendan O'Brien was a 30 year old police officer with the Oakland Police Department.

Allegations

Oakland Police Officer Brendan O'Brien committed suicide in September, 2015 a year after his wife's death, which at the time was ruled a suicide.

O'Brien left a note after his suicide that led to an initial internal affairs investigation.

A subsequent investigation ordered by a federal judge led to many Oakland police officers admitting they had lied during the first internal affairs investigation about their relationships with Celeste Guap. One officer also admitted to knowing she was underage when he had sex with her. Over a dozen officers are alleged to have had affairs with Celeste Guap while she was underage.

O’Brien’s wife, Irma Huerta Lopez, died on June 16, 2014.

Her death was ruled a suicide, but was briefly classified by homicide detectives as a potential criminal investigation.

Her family believes that O’Brien shot her and Huerta that the police ignored them.
