Kou Xiong, 38, was one of four people killed in a mass shooting at a backyard party in Fresno, California, on November 17, 2019. Friends and family had gathered to watch a football game when gunmen opened fire, leaving several others injured. The other named victims were Xy Lee, Phia Vang, and Kalaxang Thao.

Investigators described the attack as a targeted, planned assault. Law enforcement identified the Mongolian Boys Society as responsible and said the attackers selected the target residence, chose shooters, and supplied firearms. Several people were arrested and charged: Ger Lee, Anthony Montes, Porge Kue, and Billy Xiong faced special circumstances murder, attempted murder, and conspiracy charges. Federal charges were also filed against Pao Vang, Jhovanny Delgado, and Johnny Xiong for conspiring to commit murder in aid of racketeering.

The shooting devastated the local Hmong community and focused attention on gang-related violence and its consequences. Did anyone who knew Kou Xiong or was at that gathering have information that could help clarify what happened?
