Summary based on the NamUs case record (MP17551) and 5 other sources
Steve Losonczi, aged 43, was last seen on March 2, 1980, in Los Angeles, California. At the time of his disappearance, he was described as a white male with brown hair and blue eyes, standing about 5'7" and weighing around 155 pounds. Few details have surfaced regarding the circumstances surrounding his disappearance, and it remains unsolved decades later.

Despite investigations by the Los Angeles Police Department, no significant leads have emerged. His case remains open, with no available dental or DNA records on file, making it challenging to uncover new information.

Law enforcement continues to encourage anyone with information to come forward in hopes of resolving this long-standing mystery.
Last Seen: Mar 2, 1980
