A judge has ruled the attorney who prosecuted the murder trial of a New Jersey man accused of kidnapping and killing Etan Patz (AY'-tahn payts) in 1979 may participate in the retrial.

Joan Illuzzi worked for the Manhattan district attorney's office last year and prosecuted Pedro Hernandez in the missing boy case. It ended in a mistrial after one juror refused to convict.

Illuzzi then ran unsuccessfully for Staten Island district attorney. She's now returned to the Manhattan DA's office.

Hernandez's attorneys wanted Illuzzi banned from being in front of a jury because of comments she made about the case during her campaign.

The attorneys argued the comments could bias a jury. Judge Maxwell Wiley disagreed.

Six-year-old Etan vanished on his way to school in New York City.
