Retired Judge Alfred A. Delucchi has been picked to preside over Scott Peterson's double murder trial.
Delucchi's appointment comes almost a week after the prosecution disqualified Richard Arnason, who had been assigned as trial judge Jan. 21.
Peterson, 31, is accused of killing his wife and unborn son. He faces the death penalty.
A trial judge for more than three decades, Delucchi, 73, retired from Alameda County Superior Court of Alameda County in 1998 after serving for 15 years. He has been an active member of the Assigned Judges Program since .
Never miss a local story.
Delucchi has presided over 22 death-penalty trials, including the cases of People v. Tyron Robinson (involving the murder of Huey Newton), People v. Giles Nadey, People v. Jack Friend, and People v. Sarah Mitchell.
California Chief Justice Ronald George assigned Delucchi, who will preside over a hearing Monday that will address the challenge to Arnason's disqualification and other motions.
