OAKLAND — Two Oakland police officers who resigned this month in the wake of a sexual misconduct scandal have been identified by police sources.

The sources identified the officers as Terryl Smith and James Ta’ai, who both graduated from the Oakland police academy in 2014.

Oakland police announced Wednesday that two of the four officers placed on paid leave during an investigation into sexual misconduct with the daughter of a police dispatcher, had resigned, but did not divulge their names.

In response to a public records request, the department on Friday provided a list of five names of employees who resigned from the department since May 1. But a police spokeswoman refused to identify the two officers.

It’s unclear exactly how the officers are connected to the ongoing investigation, which was first sparked after Officer Brendan O’Brien committed suicide on Sept. 25. O’Brien left a suicide note naming officers who reportedly were involved with the dispatcher’s daughter who goes by the name Celeste Guap, according to a source who read the note.

The Internal Affairs unit investigated the allegations in O’Brien’s note, but it’s not known if any action was taken. However, the criminal and internal affairs probe was reopened after the federal monitor overseeing the department heard about the case.

According to the list of names provided by the department, Smith resigned Tuesday and Ta’ai resigned May 13, the day police Chief Sean Whent and Mayor Libby Schaaf held a tense news conference to address the investigation.

Smith and Ta’ai graduated from the 168th Basic Recruit Academy, the largest-ever class of recruits to graduate in Oakland at a time when the city was working to add officers to its depleted ranks.

Smith and Ta’ai could not be reached for comment. A call to the Rains Lucia Stern law firm, which frequently represents Oakland police officers, was not returned.

The Alameda County District Attorney’s Office is now doing an independent review of the sexual misconduct allegations and deaths of O’Brien and his wife, Irma Huerta Lopez, who also committed suicide, in June 2014. Her death was briefly investigated as suspicious and later ruled a suicide, but her sister has said she still has doubts that it was a suicide and blames O’Brien for her death.

On Friday morning, Chief Whent addressed 44 new officers graduating from the 174th Basic Recruit Academy and warned them to pay close attention to their moral compass.

“One risk I want you to pay close attention to is when and how you or others may lose your bearing to our shared moral compass. As police officers, you now share our obligation to uphold our code of ethics,” Whent said.

He said officers must “maintain an unsullied personal life.”

“The actions of one officer on or off duty anywhere in the country can have severe and lasting impacts on the relationship we have with our community here at home,” Whent said. “That relationship is the foundation upon which our community safety is built and nothing is worth jeopardizing that.”

Schaaf told the new officers she wasn’t going to be as “subtle” as Whent.

“You’ve chosen an amazing week to become police officers,” the mayor said. “This department is being rocked by a scandal of off duty conduct.”
