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:

Inmate: I told him what you said, that it’s the green light on. That, basically, go ahead and kill him.
Peterson: Right.
Inmate: That’s what you wanted, right? It ain’t no. It ain’t no turnin’ back.
Peterson: Okay. Alright I’m in. From the first time we talked about it, it was.
Inmate: Huh?
Peterson: From the first time we talked about it, where was no turnin’ back.
Inmate: Alright. Cause man …
Peterson: If I get some booze in here we’ll celebrate that night.

Also released, Peterson’s outburst in court during his sentencing for the murder of his third wife, Kathleen Savio.

“I did not kill Kathleen!” Peterson shouted.

In the prison recordings, Peterson also talked about dealing drugs when he got out.

Peterson, who is also the prime suspect in the disappearance of his fourth wife, Stacy, says on tape more than once that Stacy is still alive.
