At the beginning of the program, while at the crime scene, Pete the construction guy is asking if the tub, a "Godiva 3000", could be reused since it is so expensive. The tub shown is a claw foot, which is in fact a more expensive type of tub than a standard type of tub. Pete goes on to say the building is subsidized housing and the government needs all money accounted for. Since subsidized housing is contracted on a low bid process, subsidized housing would never use expensive items like a claw foot tub.
Booth says that the victim has a "living will" leaving all of his assets to one of his two wives. A living will does not serve to distribute assets after death; rather, it is a directive to medical personnel regarding treatment in the event of the patient's incapacity.
The team determines the victim had an artificial hip, but Bones fails to ask the victim's wife about it when interviewing her, which would obviously help I'm determining if he was, in fact, the victim.
