JOLIET, Ill. (AP) – Former suburban Chicago police sergeant Drew Peterson defended his apparently cavalier attitude about his arrest on charges of killing his third wife, saying that acting in a way people might consider more appropriate is “not me.”

“There’s no book written on how I’m supposed to act,” Peterson told NBC’s Matt Lauer during an interview aired on Friday’s “Today” show.

Peterson called his handcuffs “bling” and his red jail jumpsuit “spiffy” as he was led into court last week. Lauer asked Peterson if he worries such remarks will make him seem unsympathetic.

“Would it be better if I hid my head down and tried to hide my face and hunched and had tears in my eyes? I mean, no, that’s just not me,” he said by phone from the jail in Will County, where he’s been held since his May 7 arrest in the slaying of Kathleen Savio.

Peterson is also a suspect in the disappearance of his fourth wife. Peterson reiterated to Lauer that he had nothing to do with either the disappearance of Stacy Peterson or Savio’s 2004 death. Peterson maintains he believes Stacy Peterson left him for another man.

Peterson is scheduled to appear in court Monday. He’s being held on a $20 million bond.
