Video of an FBI interview with Brendt Christensen is being released.
The video was played in court last week and shows investigators interrogating Christensen about his whereabouts the night Yingying Zhang went missing. During the video, her accused killer changes his story several times.
Christensen was arrested and held later that night as prosecutors considered charging him with lying to federal agents.
