BOLINGBROOK, Illinois (AP) -- State police searched the home of a police sergeant from a Chicago suburb whose wife disappeared last month and whose former wife was found dead in her bathtub three years ago.

The warrant was executed Thursday at the home of Drew Peterson, whose wife, Stacy, was reported missing Sunday.

Investigators also searched a pond near the home with the help of a police dive team and cadaver dogs, Illinois State Police said.

Will County state's attorney's office spokesman Charles Pelkie declined to say what, if anything, investigators found. Watch police carry boxes out of Peterson home »

"No criminal charges have been filed and no one has been taken into custody," Pelkie said Thursday.

Peterson, 53, a sergeant in the Bolingbrook Police Department, has said his 23-year-old wife called him Sunday night and told him she was leaving. He said she has suffered from "mood issues" since a sister died last year and he believes she left him for another man.

Family members said Stacy Peterson failed to show up Sunday to help a relative paint a house. They said she was unhappy and asked for a divorce but would not have left her husband without taking her children, ages 2 and 4.

"I know damn well she wouldn't go without them kids," said her uncle, Gary Cales, 68, of Hemet, California.

The disappearance triggered renewed interest in the 2004 death of Drew Peterson's ex-wife Kathleen Savio, 40. She had obtained an order of protection in 2002, alleging a pattern of physical abuse and threats, according to court records. The coroner said she drowned in her tub and a coroner's jury ruled the death an accident.

Drew Peterson denied having anything to do with his ex-wife's death.

Will County State's Attorney James Glasgow has started reading through old files from the case "in light of recent developments," Pelkie has said. Glasgow, who wasn't in office when Savio died, said earlier this week that "there are some unusual circumstances in the 2004 case."

There was no water in the bathtub when Savio was found, but the coroner did find she had drowned. Investigators theorized that the water must have drained out of the tub.

Bolingbrook is about 20 miles west of Chicago.
