吴汉润原是生活在柬埔寨王国和后来红色高棉恐怖统治时代的一位华侨，祖籍广东潮州，柬埔寨华裔，正式职业是医生。

他在柬埔寨经历过赤柬政权的恐怖管治，1979年赤柬倒台后在泰国难民营当医护工作，1980年移居美国，1985年因在《战火屠城》一片中的演出而获得奥斯卡最佳男配角奖，1996年2月25日在洛杉矶唐人街被抢劫杀害。

​Dr. Haing Somnang Ngor (March 22, 1940 – February 25, 1996) was a Cambodian-born American physician, actor, and author who is best known for winning the 1985 Academy Award for Best Supporting Actor for his debut performance in the movie The Killing Fields, in which he portrayed Cambodian journalist and refugee Dith Pran. His mother was Khmer and his father was of Chinese descent. Ngor and Harold Russell are the only two non-professional actors to win an Academy Award in an acting category.

Ngor and his close friend Jack Ong established the Dr. Haing S. Ngor Foundation to assist in raising funds for Cambodian aid. As part of his humanitarian efforts, Ngor built an elementary school and operated a small sawmill that provided jobs and an income for local families.

On February 25, 1996, he was shot and killed outside his home in Chinatown, Los Angeles. Three alleged members of the "Oriental Lazy Boyz" street gang, who had prior arrests for snatching purses and jewelry, were charged with the murder. They were tried together in the Superior Court of Los Angeles County, though their cases were heard by three separate juries. Prosecutors argued that they killed Ngor because, after handing over his gold Rolex watch willingly, he refused to give them a locket that contained a photo of his late wife, My-Huoy.

All of the defendants were found guilty on April 16, 1998, the same day Pol Pot's death was confirmed in Cambodia. Tak Sun Tan was sentenced to 56 years to life; Indra Lim to 26 years to life; and Jason Chan to life sentence without parole.
