Cold Case Cops Try To Solve A Nearly Decade-Old Mystery

(CBS)  Farris played along, but secretly went to the police. Facing attempted murder charges of his own, Farris agrees to cooperate.

Authorities gave Farris a digital recorder to tape his conversations, hoping to listen in on Perry March’s plan to commit double murder.

Over two days, Farris recorded a number of conversations with Perry March.

"When we heard him talk about, 'make sure you do it when the kids are not there,' we just found it incredible," recalls Postiglione.

Next, March could be heard giving Farris the Levines' street address. Why would Perry March want the Levines murdered?

Det. Pridemore's theory: "With his hatred of the Levines, he starts calculating how much better his case will be if they were gone."

And what was Farris supposed to get out of this? A one-way ticket to the good life in Mexico. The deal was that if he killed the Levines, he could live in luxury in Mexico, with the help of Arthur March, according to his son Perry.

"My dad will stash you as long as it's necessary," Perry March could be heard telling Farris. "He'd love ya, trust me. My dad would take care of you like a son."

Perry March and Farris cooked up a code name to be used in contacting Arthur March in Mexico: "Bobby Givings."

When detectives took Farris out of the isolation unit, Perry March believed he made bond and was out on the street. In fact, in a room at a Nashville police station, Farris was making phone calls to Arthur March.

"The first conversation. They were in discussions about killing the Levines five minutes into the first conversation," Postiglione explains.

"You know about our agreement?" Farris could be heard asking Arthur March.

"No, I’m sorry, I don’t know anything. He said you call and I was just to listen and you would talk," March replied.

"I know, know things have been hard because of the Levine people, man. It’s time that all this s--- is dealt and done with," Farris said.

As Perry March sat in a Nashville jail facing trial for one murder, he thought his new pal Russell "Nate" Farris was making good on his promise and committing another.

"He thought he had Nate wrapped around his finger. The truth is, Nate had him wrapped around his finger," Postiglione says.

Using the alias "Bobby Givings," Farris made phone calls to Perry March’s father in Mexico about the hit on the Levines and it didn’t take long for Arthur March to implicate himself in the murder plot.

"Tell me what you need and I’ll take care of it if I can, possibly," March told Farris.

"The first conversation they were on, within five minutes into the conversation, they're discussing guns," says Det. Postiglione. "Within five minutes, Arthur doesn't flinch."

"Okay, you gonna take one or two out?" March asked Farris.

After two weeks working out the plan, Farris called Arthur March to tell him it was all over and that he had killed the Levines.

Farris then gave Arthur March his travel plans for their rendezvous in Mexico.

"In his mind, he's picking up Nate. Who just killed Larry and Caroline Levine. In his mind the job is done. So he's there to pick him up. Until the FBI agent approaches him [at the airport]," Postiglione explains.

Arthur March was arrested and brought back to Nashville; father and son were together again, this time behind bars and both charged with conspiracy to commit murder.
