Delveto Guzman was 27 when he was last seen at his home on South Golden Gate Boulevard in Fresno on January 3, 1998. He hasn’t been heard from since and his disappearance remains unsolved. Authorities say he had a history of alcohol abuse but that there’s no indication his disappearance was linked to any medical condition.

At the time he was 6 feet tall, about 175 pounds, with black hair and brown eyes. The case has attracted little public attention and investigators report few significant leads in the years after he vanished.

If anyone knew Delveto, saw him around South Golden Gate Boulevard on or after January 3, 1998, or has other information that could help, contact the Fresno Police Department.
