Opening Statements Begin in Murder-for-Hire Trial Against Ex-Cop Drew Peterson

Drew Peterson, the Illinois ex-cop sentenced to 38 years in prison for the murder of his third wife is in court again.

The 62-year-old is accused of offering a fellow inmate $10,000 to kill State Attorney James Glasgow.

According to prosecutors, the inmate, Antonio Smith, reported the offer to prison authorities. He then agreed to help secretly record Peterson.

The trial began on Monday. In opening arguments, the prosecution alleged that Peterson plotted to kill Glasgow out of "anger, hatred and revenge."

But Peterson's attorneys maintain that their client's innocence. In opening statements, Defense attorney Lucas Liefer warned that prosecutors would "sensationalize the heck out of this thing."

Among the evidence expected to be presented: the wiretapped conversations in which Peterson allegedly sets up the killing.

According to prosecutors, the recordings also include him discussing his 2012 conviction of first-degree murder for the death of his ex-wife, Kathleen Savio. He allegedly discusses his concern that Glasgow would prosecute him for the disappearance of his fourth wife, Stacey Peterson.

If he's convicted, Peterson faces a sentence of up to 60 years in prison. The trial is expected to last for a week.
