Convicted wife killer Drew Peterson said he's 'living the dream' in prison

Convicted killer Drew Peterson said he is 'living the dream' ever since he was moved to a maximum security federal prison. 

Peterson has been behind bars for nearly 10 years after he was arrested for the murder of his third wife, Kathleen Savio. His fourth wife, Stacy Peterson, has been missing for 12 years.  

The former Illinois police sergeant was sentenced to 38 years in prison for Savio's murder and another 40 years in prison for plotting to kill James Glasgow, the prosecutor who helped put him behind bars. 

But Peterson was in high spirits during a recent telephone interview with WFLD, revealing his life has vastly improved since his prison transfer. 

Peterson, 65, was moved from a state prison in Menard to a federal prison in Terre Haute, Indiana in February 2017. 

Officials feared that, due to the hit he placed on Glasgow, Peterson could be a threat to prison security. But the convict couldn't be happier with the change. 

'It was dirty. The mattresses I had, the pillow I had, you wouldn't put your dog on it,' he said.

'It was terrible. Urine and defecation spread on the walls.' 

'It was a horrible, horrible place. Then I come to the federal place and it's comparatively like a day care center.' 

Peterson also used the interview to maintain his innocence, claiming he wasn't behind Savio's murder or Stacy's disappearance. 

Stacy, 23, disappeared in 2007, four years after Savio, Peterson's third wife, was found dead in a bathtub. 

Savio, 40, had a 2-inch gash on the back of her head and the tub was dry. But police at the time deemed her death an accident, believing she had slipped and fallen. 

After Stacy disappeared, authorities became increasingly suspicious of Peterson.
