Five individuals who were arrested last month in connection with the disappearance of Israeli soldier Guy Hever have been released without charge, according to reports from Hebrew media. The arrests came amid renewed interest and a reported breakthrough in the decades-old case, which has long been under a strict gag order. Guy Hever vanished in August 1997 after leaving his post on the Golan Heights with his rifle, and no trace of him has ever been found. The case continues to be one of the country's most enduring and mysterious unsolved disappearances.
