Authorities claim Peterson mystery will be resolved

The new year should bring new information that will help investigators determine what happened to at least one of Drew Peterson's wives, Will County State's Attorney James Glasgow said Tuesday.

Though Glasgow made a similar, still-unfulfilled prediction two months ago, he remains upbeat that authorities will solve the 2007 disappearance of Stacy Peterson and the 2004 drowning death of Kathleen Savio.

"I'm very positive. I'm very encouraged by the work the police have done," said Glasgow, speaking about the cases for the first time in several months. "We are not at a dead end by any stretch of the imagination."

A grand jury that for 14 months has been probing Stacy Peterson's disappearance and Savio's death will resume hearing evidence next month, Glasgow confirmed.

"It'll be meeting next year," Glasgow said of the grand jury, which also has heard evidence in the April 2007 still-unsolved disappearance of Plainfield mom Lisa Stebic.

In October -- near the one-year anniversary of Stacy Peterson's disappearance -- Glasgow said he expected a resolution to at least one of the cases in the "near future." He wouldn't clarify that timetable Tuesday.

Drew Peterson -- a 54-year-old ex-Bolingbrook cop who has been named a suspect in Stacy's disappearance -- isn't worried about the lengthy investigation because he's done nothing wrong, his attorney said.

"Mr. Glasgow is a fine state's attorney but he can't make a case where none exists," attorney Joel Brodsky said. "There's no evidence that ties Drew to Kathleen's death or Stacy's disappearance."
