LACI PETERSON CASE Both sides must give documents to judge

The defense and prosecution also debated the reliability of tracking dogs.
REDWOOD CITY, Calif. (AP) -- A judge told attorneys in Scott Peterson's double-murder trial they cannot file anything without his prior review after prosecutors alleged in court documents a motive for Laci Peterson's murder.
Prosecutors sketched broad outlines of what they believe led Scott Peterson to kill his wife, Laci, citing Peterson's affair with massage therapist Amber Frey and his conflicting statements about it to police.
Defense attorneys said Tuesday the document contained "out-and-out falsehoods" designed to grab headlines. Prosecutors told the judge they were rebutting defense attorney Mark Geragos' request that a judge exclude Peterson's public statements from his trial.
Jury selection is scheduled to start next week. Peterson, 31, could get the death penalty if convicted.
Tracking dogs in question
Also Tuesday, attorneys debated the reliability of tracking dogs used during the investigation. Authorities used the dogs to find Peterson's wife, Laci, after her disappearance Dec. 24, 2002, and defense lawyers want the judge to toss out evidence gathered by the canines.
Defense attorney Pat Harris questioned the credentials of Cindee Valentin and the experience of her bloodhound, Merlin. Harris said factors including the dog's mood could have led to mistakes. He also said Valentin had no way of knowing whether Merlin was tracking a scent at all. "He was certainly bouncing around all over the place, wasn't he?" Harris asked.
Valentin said her dog was well-trained and she could recognize when he picked up a scent.
Harris suggested that investigators were on a single-minded pursuit to get Peterson.
He said Merlin picked up Laci Peterson's scent outside the warehouse, but detectives stopped the dog because he was headed in the wrong direction, an episode Valentin acknowledged was true.
