Zai Chao Wu was an 18-year-old Sacramento resident killed by a stray bullet on August 31, 2015. He was in his bedroom playing a video game on Lemon Hill Avenue when a bullet pierced the window and struck him in the head. He was taken to UC Davis Medical Center and died the next day.

Police say the gunfire came from a nearby apartment complex during a gang-related altercation and that Wu was not the intended target. He had recently graduated from Hiram Johnson High School and started at Sacramento City College; family described him as kind-hearted and a mentor to his younger brother. Investigators have sought witnesses and asked the public for information, but the case remains unsolved.

Does anyone who lived near Lemon Hill Avenue in 2015 have information that could help the investigation?
