Besides with a history of being one of the biggest crime bosses in Los Angeles, especially in Chinatown, Uncle Benny also has a history with drug dealing as part of his business. According to Riggs and Murtaugh, they had dealings with handling Uncle Benny when he was dealing and trafficking heroin.
Uncle Benny ran a front busines, a restaurant called Uncle Benny's Restaurant. meeting with George Proody, an immigration consultant regarding the importation of immigrants from China. When his assistant reports that the cargo ship was impounded, Uncle Benny is most disappointed and he tells Proody that he has to go. The consultant is killed by a train later that night.
Benny is later visited by Martin Riggs, Roger Murtaughm and Lee Butters. The detectives believe Uncle Benny is responsible for the Chinese slaves being brought to the docking bay the other night, but Benny lies and says he doesn't know anything about it. When Riggs insults his right-hand enforcer Wah Sing Ku, he tells him he doesn't speak English. He tells them he is very busy and forces them to leave, since they don't have any probable cause. Then Riggs shoots the transparent glass when Benny politely showed them the door. He also pulls the fire alarm, which sets off the sprinkler and gets Benny soaked.
A couple of days later, while Benny has a dental appointment with Dr. Samuel Cheng, Riggs, Murtaugh, and Butters return to see him and come up with a way they can get him to talk and admit about kidnapping the slaves and the Hong family. Leo is used to distract Dr. Cheng, while Riggs, Murtaugh, and Butters interrogate Uncle Benny. Refusing to talk, the trio use laughing gas within the room to extract the truth from him. Uncle Benny talked about the Four Fathers, which they misinterpreted as the forfathers. While under the influence of the laughing gas, Uncle Benny makes a confession that he is sleeping with his wife's two sisters.
Later, at the site of a warehouse, the Chinese kingpin grabs a sheet full of counterfeit Chinese money and proudly smiles at it. Uncle Benny would met his demise right there being strangled by Wah Sing Ku with a ligature, because he had revealed the plan to Riggs, Murtaugh, and Butters because he had outlived his usefulness. When the detectives visit the crime scene, Riggs looks at his dead body and noted how he was "actually starting to like the old goat".
