so they wire the young skinhead, nicassio, and send him into the lion's den. >> if i go to trial, what am i going to say? >> do not make that statement in trial. >> he tells nicassio not to bring his name into it. another bit of evidence, but they need more. and then merriman, who has no idea at all that this is being recorded, gives the investigators an important clue. >> don't tell me that. you're making me nervous. you [ bleep ] hauled that [ bleep ], you know what i mean? >> it's subtle, but there it is. a key piece of the puzzle falls into place. when merriman hisses that nicassio helped haul the body, helped get rid of the evidence. the prosecutor knows it the instant he hears it. in his own crude way, merriman is confirming nicassio's credibility. he didn't say he killed her or raped her. he said, you helped bury her, you're liable.
