Drew Walter Peterson (born January 5, 1954) is a retired Bolingbrook, Illinois police sergeant and convicted felon who first received national publicity in the United States in 2007 when his fourth wife, Stacy Ann Cales Peterson, disappeared.
Although law enforcement and the public suspected foul play, she has never been found, and Peterson has not been charged in her case.
Four search warrants were issued and carried out on Peterson's property following Stacy's disappearance, including the seizure of his firearms and both his and Stacy's vehicles.
Following the mysterious disappearance of Stacy on October 28, 2007, Peterson announced his plans to retire as a Bolingbrook police sergeant effective December 2007.
Her death was initially ruled an accidental drowning by a coroner's jury that included a police officer who personally knew Peterson and assured the other jurors that Peterson was a good man who would never hurt his wife. Michael Baden, a former New York City chief medical examiner who conducted the examination at the request of Savio's relatives and Fox News, concluded that she died of drowning following a struggle when her body was placed in the bathtub.
as has her daughter, who lived in the household from the age of 8 to the age of 17.
Peterson's stepbrother, Thomas Morphey, who has a history of drug and alcohol addiction, attempted suicide two days after allegedly helping Drew carry a large blue plastic container from Peterson's Bolingbrook home to his sport utility vehicle, fearing he may have helped dispose of the body of Stacy Peterson.
Neighbors reported seeing Peterson and another man hauling a 55-gallon barrel, large enough to hold a person, out of the house shortly after Stacy's disappearance.
Stacy Peterson was officially reported missing in the early hours of October 29, 2007, after her sister, Cassandra Cales, failed to hear from her when expected.
Drew Peterson claims that Stacy called him at 9 p.m.
On February 9, 2015, Peterson was charged with two additional felonies, solicitation of murder and solicitation of murder for hire, for attempting to have Will County State's Attorney James Glasgow killed.
