Metzger kidnapped Chloe Robertson, the wife of an FBI Agent; Richard Bannerman. He blackmailed Bannerman to receive a list of undercover agents planted in criminal and terrorist organizations. After receiving the list, he killed the couple with brass knuckles, damaging his hand in the process, which he told everyone was the result of carpal tunnel.
He set up a trade with Kevin O'Donnell to give him the list for two million dollars. Booth and Jared planted themselves into the plan to steal the money from Victor Masbourian to get the list. The heist left Jared dead and Booth severely injured by the gunshot to the chest. Metzger wanted Kevin to kill Booth threatening to call off the deal because he knew that Booth planted himself to get the list.
After erasing the hard drive on his computer with a virus sent over an e-mail, he started manipulating the team to steer the investigation with the information he allowed them to find. After discovering cause of death for Bannerman, Brennan realized that Metzger was the killer because of the damage to his hand. At first, Metzger was being exceedingly difficult with Aubrey and Agent Miller, but after Brennan started to torture him by breaking the already compromised bones in his wrist, he disclosed the location of the planned trade where Booth was hiding with Kevin O'Donnell. Because of the torture, his sentence was shortened, according to Caroline Julian, "from 900 years to 600 years," which she can live with.
