Summary based on the NamUs case record (MP12916)
Romeo Sierra-Portillo, a 53-year-old businessman from Guatemala, was last seen on September 26, 2006, in Lawndale, California. On that day, he called his wife to inform her that he was staying at the Traveler's Inn Motel in Lawndale, where he was conducting business. This was the last communication anyone had with him, and he has not been heard from since. Sierra-Portillo, who often traveled to the United States for business, vanished under mysterious circumstances, and there has been little information available regarding his whereabouts.

He was described as a Hispanic male, standing 5 feet 5 inches tall and weighing around 170 pounds, with brown hair. Despite his disappearance being reported, no significant leads or updates have surfaced in the years following his last known contact. His case remains unresolved, and authorities continue to seek information that could provide any insights into his fate.
