Summary based on the NamUs case record (MP106993) and 2 other sources
Alberto Lira Zavala, a 46-year-old man from Fontana, California, was last seen by his family between September 19 and September 22, 2020, in the vicinity of Palmetto Avenue and Foothill Boulevard. Zavala, who did not own a vehicle or a cellular phone at the time, has not been heard from since. His disappearance has left investigators with few leads, and the details surrounding his case remain unclear.

Zavala is described as 5'8", weighing 170 pounds, with brown hair and brown eyes. He has several distinctive tattoos, including the name "Isaac" on his chest, his last name "Zavala" across his back, and a woman’s face with the words "My Queen" on his left shoulder. Despite ongoing efforts, there have been no significant developments in his case.

The Fontana Police Department continues to investigate his disappearance and urges anyone with information to contact them.
