Benjamin Joi Barros, a 34-year-old man, was last seen on June 29, 2004, in Cotati, California. He was reportedly leaving his residence on East Cotati Avenue at approximately 4:45 a.m., stating he had an appointment. After that, he vanished and has not been seen or heard from since. Some reports list his disappearance date as May 1, 2004, but June 29 is commonly accepted as the accurate date. At the time of his disappearance, Barros stood between 5'11" and 6'2" tall, weighed around 150 to 210 pounds, and had gray hair and hazel eyes. He was known to go by the nickname "Ben."
