CHICAGO (CBS) — From a courtroom outburst to prison cell conversations, the recordings presented at Drew Peterson’s latest trial were released on Tuesday, including one in which Peterson talks about killing the man who put him behind bars for murder.

Many of these recordings were made secretly and took place between the former Bolingbrook police sergeant and fellow Menard Correctional inmate Antonio Smith, a gang member.

Some of Peterson’s words from that trial were used to set up last month’s trial, in which he was convicted of trying to have Will County State’s Attorney James Glasgow killed.

Much of the evidence in that downstate trail centered on those prison recordings.

In one of those conversations, the plot to kill Glasgow is discussed:
