Wei Shen (born 1984) is a Chinese-American HKPD chief inspector. Shen was born and raised in Hong Kong and was friends with future Sun On Yee members Jackie Ma, Winston Chu and Sam "Dogeyes" Lin. At age 10, Shen and his family moved to San Francisco in an attempt to help his older sister Mimi overcome her drug addiction.
Shen attended PS 121 High School, and graduated in 2002 with honors. He then enrolled at San Francisco State University in September 2002, majoring in politics. He voluntarily departed SF State in 2004 to pursue other career options.
In June 2006, Shen applied to the San Francisco Police Department and graduated at the top of the 2007 police academy class. While he had no criminal record or known criminal associates. Wei also tested negative on all drug tests. Despite a clean record he was reprimanded six times for violent behavior and fighting, but due to his intelligence, physical skill, and a natural aptitude for police work, he was still thought of highly by his superiors. Shen demonstrated a familiarity with the Asian gang structure and culture in San Francisco, and a deep understanding of the way in which these criminal organizations operate. Due to the department’s lack of qualified Asian-American candidates and the demand for Cantonese-speaking officers, he was highly recommended to be assigned immediately to the plainclothes anti-Tong task force.
