Ping Wu is a teenage Chinese immigrant who was illegally immigrated in by a smuggling mob led by Ricky Yao.
History[]
Ping was blackmailed and threatened into paying a fee for her immigration in the form of prostitution. The rest of her family was also under Yao's thumb with debts they were force to pay, from sex trafficking to finances. When Ping's mother Jiao was murdered, her aunt, Li Mei, was obligated to pay Jiao's debts. When Li Mei was brutalized, it led to the discovery of Ping's forced prostitution from a photograph Li Mei was sent as part of her blackmail.
Li Mei was encouraged to get Yao arrested in a sting. It worked, but he posted bail and was close to getting Ping killed at a mercenary's hand. When the brothel she was imprisoned at was stormed, a standoff with the mercenary was initiated while he held a gun to Ping, ready to kill her. Stabler shot him dead, and Ping was then taken to an ambulance and reunited with Li Mei, who accompanied her for the ride. (SVU: "Debt")
