Drew Peterson murder trial jury asks for definition of the word "unanimous"

(CBS/AP) JOLIET, Ill. - Jurors deliberating in the Drew Peterson murder trial have sent a note to the judge asking for a definition of the word "unanimous" on their second day of deliberations.

After a brief discussion with attorneys the judge said he would respond with a note saying it "indicates the agreement of all on the matter at hand."

Peterson has pleaded not guilty to murdering his third wife, Kathleen Savio, in 2004. The former Illinois police officer was charged after his fourth wife, Stacy Peterson, disappeared in 2007.

Jurors on Wednesday asked to review evidence including transcripts of hearsay testimony given by witnesses, including Stacy Peterson's former pastor and Kathleen Savio's divorce attorney. That could mean they're grappling with statements the two wives allegedly made to others implicating Peterson.

Because of a botched initial investigation, detectives collected no physical evidence in Saviuo's death. So Illinois legislators passed a law aimed specifically at Peterson, allowing prosecutors to pursue a conviction based substantially on such statements, which are often barred from trials as "hearsay" evidence.

The Chicago Tribune reported the jury is also asking to see autopsy photos of Savio's body and the bathtub where she was found.
