On August 22, 1928, Yeung Soon Fong, aged 38, was tragically killed in a mass murder incident on a farm near Fairfield, California. This horrific event was orchestrated by Leung Ying, also known as Loy Yeung, who was a Chinese mass murderer. Armed with a rifle and a hatchet, and reportedly under the influence of cocaine, Ying attacked the residents and workers at the Bryan ranch, where Yeung Soon Fong was present. The attack resulted in the deaths of 11 people, including Yeung Soon Fong, and left four others wounded.
Leung Ying's motive for the massacre was rooted in a personal vendetta. He had previously been employed at the Bryan ranch but was dismissed after an incident involving Wong Gee's daughter, Nellie. Ying claimed that the Wong Gee family had tried to kill him with poisoned food, which fueled his desire for revenge. On the day of the attack, Ying first entered an underground gambling room where he shot Wong Gee and another worker, Cheung Yueng. He then proceeded to kill others on the farm, including Yeung Soon Fong, using both his rifle and hatchet.
Following the massacre, Ying fled the scene but was apprehended by police the next day. He was swiftly sentenced to death on August 31, 1928. However, Ying did not live to face his execution. On October 22, 1928, he committed suicide in his prison cell at San Quentin Prison by hanging himself with a towel. This case was one of the worst mass murders in California's history at the time, surpassing previous incidents in terms of the number of victims.
The investigation into the massacre revealed Ying's troubled past, including his involvement in narcotics and previous criminal activities. He had a reputation as a dangerous individual, having boasted about killing three people in a tong war. His actions on August 22, 1928, were a culmination of his violent tendencies and personal grievances, leading to a tragic loss of life, including that of Yeung Soon Fong.
