Humberto Cisneros Ruiz, 23, was shot dead in his Dos Palos home on January 20, 2017. Police were called early that morning to a residence on the 1900 block of South McDonald Road and found him inside with a gunshot wound to his upper torso; he was pronounced dead at the scene.

Authorities identified his roommate, Omar Villafana, then 29, as the primary suspect. Villafana was last seen fleeing on foot wearing a red hoodie, gray sweatpants, and cowboy boots, and was believed to be armed. The Dos Palos community was described as shocked by the violence, and police urged anyone with information to come forward as the search continued.

What did neighbors or visitors to that block notice that morning or in the days before the shooting?
