Drew Peterson: Wife Pulled Trigger in Gun Incident

Former police officer Drew Peterson acknowledged that a gun did go off in his home a few months before his wife disappeared but says it was his wife who pulled the trigger.

Peterson's sister-in-law claimed he fired a gun, with the bullet almost striking his wife. But Peterson told the Chicago Tribune for a story Thursday that his wife accidentally fired the gun he'd bought her as a gift.

"She had a fascination with guns," he said of his missing wife, Stacy Peterson. "I bought her a Glock for Valentine's (Day) — because nothing says I love you like a Glock. That was our joke."

Stacy Peterson, 23, vanished in late October and her husband, a 53-year-old former police sergeant in the Bolingbrook Police Department has been named a suspect in her disappearance. Investigators say they believe the case may be a homicide.

Drew Peterson suggested Stacy Peterson fabricated the story reported to her sister because "she was embarrassed about it."

But Stacy Peterson's family spokeswoman, Pamela Bosco, called Peterson's explanation "idiotic" and said the sister, Cassandra Cales stands by her account of what happened.
