(KRON) — The fourth suspect in the killing of Oakland police officer Tuan Le has been charged with murder, Alameda County District Attorney Pamela Price said on Thursday.

Sebron Russell, 28, was originally charged with three counts of burglary. He now joins Marquise Cooper, Mark Sanders and Allen Brown as being charged for Le’s murder.

Russell was also charged with the attempted murder of Le’s partner, Donald McKinney. In addition, he was charged with kidnapping to commit robbery in connection to a “robbery incident” that happened on July 25, 2019.

“We will not stop our pursuit of justice for Officer Le and his family until everyone who participated in his murder is held accountable,” said Price. “We will follow the evidence wherever it leads, amend any charges against these four defendants as needed, and bring charges against anyone else allegedly involved in the killing of this Oakland Police Officer.”

Le was fatally shot on Dec. 29, 2023, when responding to a burglarized business in the area of Jack London Square. He was working undercover when one of the suspects opened fire on him.

Prosecutors believe it was Sanders, 27, who pulled the trigger and killed Le. Oakland officers arrested him in Livermore using Le’s handcuffs.

The four defendants are scheduled to go to court for a preliminary hearing on Monday.
