Ruben Cantu was 34 when he disappeared from Laredo, Texas. He was last seen on March 29, 1995, and was believed to be traveling by Greyhound bus from Laredo to San Antonio. Ruben was described as 5 feet 5 inches to 5 feet 8 inches tall, about 160 to 170 pounds, with black hair and brown eyes. He suffered from mental health issues and was considered disabled, which increased concern when he never arrived in San Antonio.

His disappearance is classified as endangered missing and is listed in databases such as NamUs. No new leads have emerged and investigators continue to seek information that could explain what happened during or after his bus journey. If anyone has memories of seeing Ruben around March 29, 1995, or information about his travel that day, please share what is known.
