The man who found Drew Peterson's third wife drowned in her dry bathtub was arrested by the Naperville police in connection with battering his brother.
Steve Carcerano, 44, of Bolingbrook was taken into custody March 27 in connection with an incident three weeks earlier near the intersection of Freedom Drive and Warrenville Road.
Carcerano and his brother were together in a vehicle at the time of the reported battery, said Naperville police Sgt. Gregg Bell.
"He put his brother out of the car," Bell said.
Witnesses called police to report the matter and Naperville officers secured a warrant for Carcerano's arrest.
Carcerano is due back in DuPage County court on May 2.
Bell said Carcerano's brother did not suffer any serious injuries in the alleged attack.
Carcerano could not be reached for comment.
The Naperville arrest was his second in that town in less than four years. He was arrested on a drunken driving charge in 2008 and eventually pleaded guilty, according to court records.
Carcerano's ties to Peterson
Carcerano was a neighbor of Peterson's third wife, Kathleen Savio. In March 2004, Peterson told Carcerano to go into Savio's home after he had failed to contact her in several days. Peterson waited outside while Carcerano went in and upstairs.
Carcerano found Savio's body laying dead in her bathtub. After he made the grisly discovery, Carcerano said Peterson rushed up the stairs after him and called out, “Oh, my God!”
Three and a half years later, following the mysterious disappearance of Peterson's next wife, Stacy Peterson, Carcerano and Drew Peterson made the Bolingbrook social scene, regularly showing up in some of the town's hottest night spots, such as Tailgater's.
In my 2008 nonfiction sensation Fatal Vows: The Tragic Wives of Sergeant Drew Peterson, Carcerano explained "it was important for him to accompany Peterson to a bar or restaurant so that he could be 'the eyes' in case 'somebody tries to stick a knife in Drew’s neck.'”
Carcerano was also instrumental in brokering a sit-down between Drew Peterson and a Las Vegas "talent" representative so the two could discuss plans for a reality show, according to two sources.
Peterson and the representative met in Las Vegas just months before Peterson was arrested and charged with murdering Savio. while he awaits the start of his murder trial.
Carcerano was also the go-between when Drew Peterson made the acquaintance of 22-year-old tanning salon worker Kim Matuska. Matuska later spent the night at the home of Drew Peterson, a disgraced Bolingbrook cop 32-years her senior.
Carcerano knew Matuska from frequenting her tanning salon and introduced her to Peterson, whose wife had been missing for seven months at that point.
