Summary based on the NamUs case record (MP43253) and 6 other sources
In the late summer of 2013, Brian Robert Giron, a 37-year-old man known to some by the nickname Semas, attended a boxing match in Bensenville, Illinois. This evening would become the last time he was definitively seen by those who knew him. According to his family, it was not entirely unusual for Brian to disappear for short periods, but there was a different, more permanent feeling to this absence. As days turned into weeks without any contact, the worry for his safety grew into a formal missing person investigation, a painful chapter that his family had hoped they would never have to navigate. He has not been seen or heard from since that day in August. The case was officially created on April 28, 2018, years after his initial disappearance.

Brian is described as a male of both Hispanic/Latino and White/Caucasian descent, with a family heritage that is a blend of Guatemalan, Bohemian, and British roots. At the time he went missing, he stood between 5 feet 10 inches and 6 feet tall, with a heavy build, weighing between 270 and 280 pounds. He had brown eyes, wore glasses, and had brown facial hair. On the night he was last seen, he was wearing a plaid, short-sleeve shirt, shorts that were a mix of brown, yellow, and tan, and a hat. He had distinct scars that would make him identifiable: a burn scar on the bottom of his right foot and another scar that ran from his wrist to his elbow on one of his arms.

The Bensenville Police Department opened an investigation into Brian's disappearance, but the circumstances surrounding his case have remained shrouded in mystery. The initial report noted his history of brief disappearances, but this particular instance was different, as he never returned. With no clear evidence of foul play or reasons for him to voluntarily leave his life behind permanently, investigators and his family were left with few leads to follow. The passage of years has not brought any significant developments, and his case remains an open and unresolved matter. The overview of Brian Giron's case is one of quiet uncertainty; a man who vanished after a public event, leaving a void and a series of unanswered questions for his loved ones.
