Willis was raised by his mother in Dorchester in the 1970s. His father left the family when John was 2 years old. Following his mother's sudden death when he was 14, Willis was left to live by himself.
Criminal career
While working as a bouncer at a bar in Boston frequented by Chinese crime figures, Willis intervened in a fight on the behalf of Chinese gangster, Vapeng "John" Joe. As thanks, Joe gave Willis a card with a number written on it and told Willis to call if he ever needed anything. Soon, broke and needing a place to stay, Willis called the number. He was taken to a home occupied by the Chinese gangPing On. Multiple reports state that Willis was then "adopted" by a Chinese family linked to the gang.
New York
After being initiated into gang life in Boston, Willis was sent to New York to act as a bodyguard and bagman for a Chinese gangster in the city. While in New York, Willis began to learn Chinese as a way to pick upAsian women, eventually becoming fluent. His language skills were crucial to his rise within the Chinese organized crime hierarchy. Willis eventually also learned Vietnamese.
Return to Boston
In the 1990s, Willis was sent back to Boston to work for a mid-level gangster named Bai Ming. However, a Chinese turf war broke out which resulted in Bai Ming being the most important gangster left standing in Boston's Chinatown. Willis, by virtue of being Bai Ming's second in command, saw his status in Chinese organized crime soar.
Prison
Willis was convicted and jailed for extortion and then, in 2000, received a five–year sentence for dealing heroin. While in prison, Willis organized an Oxycontin trafficking ring from Florida to Massachusetts. Upon his release from prison, he became heavily involved in drug dealing and money laundering against the wishes of his Chinese organized crime peers. In August 2013, Willis was convicted of drug trafficking and money laundering for his role in the $4 million Oxycontin drug ring. He received a 20-year sentence.
