Peterson was fired in 2010 after he testified at Grand Jury about receiving guns and money from his father, Drew Peterson, shortly after Stacy Peterson went missing, effectively interfering with an ongoing investigation.
The younger Peterson argued that guns were often lent between police officers and that he was unaware of an investigation at the time that he accepted the guns from Drew Peterson.
But, in truth the story of Stacy Peterson’s disappearance was already on the news when the gun hand off happened on October 30, 2007, and even Stephen testified that he had accepted the guns because they were his father’s “favorites” and that Sergeant Peterson didn’t want them to be damaged when they were seized, which indicated that they were both aware of an ongoing investigation.
Judge Sheen’s decision concludes that:
“In this case, it was in no way arbitrary or unreasonable for the Board to conclude that Officer Peterson exhibited conduct incompatible with continued service as a police officer. Therefore, this Court finds that Officer Peterson’s conduct, when viewed in its entirety, warrants the sanction of discharge.”
Peterson has indicated that he will appeal this decision.
