Cops again search Peterson's Bolingbrook house

Authorities executed another search warrant late Tuesday in the case of a former Bolingbrook Chicago police sergeant suspected in his 23-year-old wife's disappearance.

The warrant that Illinois State Police delivered to Drew Peterson's Bolingbrook home on Tuesday evening dealt with items inside two vehicles already seized from the residence, said Charles Pelkie, a spokesman for the Will County state's attorney's office.

"It expands the scope of the initial search warrant regarding items in his vehicles," Pelkie said. He declined to elaborate, including what items police found or were searching for.

Drew Peterson's attorney, Joel Brodsky, told WFLD-TV that the warrant says the items "may have been utilized in commission of the offense of first-degree murder or the concealment of a homicidal death."

The warrant also indicates interest in trace elements of several materials, including blue plastic, Brodsky told the Fox affiliate.

A relative of Drew Peterson reportedly helped him move a heavy container out of his home and put it the family's sport-utility vehicle the day his wife vanished, an allegation Brodsky denied last week. A nonprofit group helping to search for Stacy Peterson has said police asked them to look for a blue plastic barrel large enough to hide a body.

Brodsky did not immediately return messages from The Associated Press on Tuesday night seeking comment.

Also on Tuesday night, reporters asked Drew Peterson whether he expected to be charged.

"With all the hoopla, it's hard to believe something won't happen," Peterson said.

Illinois State Police did not immediately return a message after business hours Tuesday from The Associated Press.

Tuesday's warrant was the not the first police have executed since Peterson's wife disappeared in late October.

On Nov. 1, state police seized two vehicles at the home the Petersons shared with their children -- a GMC Denali and a Pontiac Grand Prix.

Authorities have named Drew Peterson as a suspect in what they have said is a potential homicide. Prosecutors also are reviewing the death of Drew Peterson's third wife, Kathleen Savio, and have said the drowning, deemed accidental at the time, may have been a homicide staged to look that way. Peterson has not been named a suspect in her death.

Brodsky asked a judge last week to order investigators to return property seized from the family's home, including the two cars, 11 guns, iPods, school supplies, computers and nearly two-dozen CDs.

Will County Judge Dan Rozek was expected to consider the matter on Dec. 12.

Brodsky has said that Drew Peterson is entitled to his weapons, which were taken from a locked safe Nov. 1.
