The Mentalist Episode 2.19 Blood Money

During a sting, the CBI team arrests a hitman who admits to the killing of an assistant D.A. At the preliminary hearing, his defense attorney takes CBI apart because prior to the arrest, Jane entered the hitman's apartment without a warrant. The case is tossed and the hitman goes free. Now Jane and company must start the investigation over from scratch. Having obtained new evidence of the hit man's guilt in the murder, the team ascends on his home to arrest him. As they lead him out of the house, he falls to the ground, dead from a sniper's bullet. The CBI team must now find the killer that was hired to silence the hitman.
