Summary based on the NamUs case record (MP35775) and 6 other sources
Steven Mark Dadasovich, 25 years old at the time of his disappearance, was last seen on August 22, 1981, in Stockton, California. Standing 6'1" and weighing approximately 185 pounds, Dadasovich had brown hair and brown eyes. He was known to have distinctive tattoos: a bull's head on his upper right arm and an eagle holding a skull on his upper left arm. He went by the nickname "Daz" and may have also used his middle name, Mark.

At the time of his disappearance, Dadasovich was riding a Harley-Davidson motorcycle, but few other details about his last known actions or circumstances have been revealed. Despite being missing for decades, his case remains unsolved, and investigators are still seeking information. The San Joaquin County Sheriff's Department is handling the case, and dental records are available for identification purposes.

Dadasovich’s disappearance remains a mystery, with law enforcement urging anyone with information to come forward in hopes of solving the case.
