SAN FRANCISCO (NewsNation Now) — Scott Peterson’s case will return to the courtroom Friday nearly 16 years after he was first convicted of murdering his wife and unborn child, the Stanislaus County District Attorney announced.

Earlier this month, the California Supreme Court ordered Peterson’s 2004 convictions for killing his pregnant wife Laci and their unborn son 18 years ago to be re-examined due to possible juror misconduct.

According to court documents, the judge “made a series of clear and significant errors in jury selection that, under long-standing United States Supreme Court precedent, undermined Peterson’s right to an impartial jury at the penalty phase.”

Peterson’s death sentence was overturned on an appeal in August.

A judge in Stanislaus County will determine whether Peterson needs a public defender or hires his own attorney. It is unknown if Peterson will appear in person or by video from San Quentin State Prison or if he appears at all.
