Judge Richard Schoenstedt made the ruling during a Wednesday morning hearing. The only condition is that Peterson must agree not to challenge the validity of photographs of the property or documents related to them at any future trial.
"He's happy that the judge ruled and he's going to get his property back. He has car. They can have their computer back. And these things really aren't evidence of anything and that's all from what the judge said. It's not probable cause for the government to keep this property," said Andrew Abood, Drew Peterson's attorney.
Authorities say Illinois State Police have revoked Drew Peterson's state ID card that allows the former Bolingbrook police officer to own firearms. Since he no longer has a Firearms Owners Identification Card, he can't get the guns back.
"We feel this was a reasonable order at this point and we don't have a problem with it. The key thing that is important to remember is that the judge did included in his order with regard to the return of the weapons that Mr. Peterson be in possession of an FOID card," said Charles Pelkie, Will Co. State's Attorney spokesman.
The former Bolingbrook police officer has been named a suspect in Stacy Peterson's October disappearance. He hasn't been charged with any crime and denies having anything to do with her disappearance.Also Wednesday, ABC News has learned that a grand jury has subpoenaed the two teenage sons of Drew Peterson. Their mother was Peterson's third wife, the late Kathleen Savio.
