On Tuesday after a three-day weekend in the trial, ABC News reported that Diana Grandel, 40, the woman whom Peterson wrote love letters to while in jail, told ABC News that some of Peterson's letters, including the ones that dealt with details of Savio's death and Stacy Peterson's disappearance, burned in a house fire in 2010.
In the first week of the Drew Peterson trial, a judge had considered a defense motion for a mistrial. Will County State's Attorney James Glasgow said he is looking forward to continuing to build his case Tuesday.
"We got the first week under our belt and have dozens of witnesses to go, so at least getting the thing started is going to keep us rolling," he said.
Glasgow is expected to call Savio's sister back to the witness stand. She testified that before Savio's 2004 death, Savio told her Peterson threatened to kill her. During cross-examination, Peterson's defense lawyer raised doubts about her credibility because she did not immediately raise the issue with investigators.
The former Bolingbrook police sergeant is charged with murdering his third wife, but he has maintained her death was a bathtub accident. Peterson he's legal team said their client remains hopeful.
Also expected on the stand Tuesday are two investigators who originally led the investigation into Savio's death. Prosecutors say they were too quick to rule out foul play because prosecutors say her death was a murder.
