S13, E9: The charred body of a young Asian female is found outside the upscale penthouse of Li Chen (Tzi Ma), the Deputy Counsel General to China. It takes a while to identify the victim, who is a Falon Gong follower named Helen Quan. But the Medical Examiner explains what was initially thought to be a suicide is a homicide since it's evident she was strangled before burned. Tommy Wong (Ken Leung), a driver for an elderly woman in the building is questioned. He initially claims to know nothing but when detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) figure out he knew Helen, he admits to that. They then question Chen, who mysteriously has a sculpture by a local artist from Tianjen, China, where Helen's mother is a prisoner.
