Summary based on the NamUs case record (MP73233) and 7 other sources
Augustine Macias, a 74-year-old resident of Simi Valley, California, went missing on November 20, 2014. He was last seen leaving his home for his usual daily walk near Tapo Street and Los Angeles Avenue. Macias, who suffered from dementia, never returned from that walk, leading to extensive search efforts by local authorities and volunteers. He was wearing a light brown long-sleeve shirt, a black wool jacket, blue jeans, black shoes, and a blue baseball cap with a yellow "S" insignia at the time of his disappearance.

Despite numerous search efforts, including an organized search in early 2015, no confirmed signs of his whereabouts have been discovered. Some personal items of interest were found during one search, but they were never definitively linked to Macias. His case remains unsolved, and authorities have classified him as at risk due to his medical condition.

Macias' family and local authorities continue to seek any information that might help locate him. His case is still open with the Simi Valley Police Department.
