Jurors in Scott Peterson's double murder trial have told the judge they may be unable to reach a verdict.
Judge Alfred Delucchi summoned jurors to the courtroom Monday, just an hour and half after they resumed deliberations for a fourth day. He told the panel he wanted to reissue instructions to them on several key points.
But the jury is indicating that it could be deadlocked.
Earlier Monday, the jurors got to see up-close the boat prosecutors claim Peterson used to dispose of his wife's body.
After that examination, defense lawyer Mark Geragos sought a mistrial. He claimed jurors violated the judge's order by doing "a juror experiment" when several of the panelists got inside the boat and rocked it from side to side.
The judge quickly denied the motion.
