Summary based on the NamUs case record (MP14996) and 3 other sources
Benjamin Lopez Jr., 27, was last heard from on June 2, 1991, when he called his aunt from Anchorage, Alaska, after leaving his home in Stockton, California, on May 31. He had flown from Bellingham, Washington, to Anchorage, leaving his vehicle behind. During the call, Benjamin told his aunt that he planned to go mountain climbing and would return home in three weeks, but he was never heard from again. At the time of his disappearance, Benjamin was suffering from brain cancer and had a metal plate surgically implanted in his skull, which left visible scars on his forehead.

Benjamin's disappearance remains unsolved, and his case is classified as endangered missing. He is described as a white/Hispanic male, 5'8" tall, weighing around 140 pounds, with brown hair and eyes. Despite the passage of time, there have been no significant developments, and authorities from both Alaska and California continue to search for information regarding his whereabouts. Investigators urge anyone with information to contact the Alaska State Troopers or Stockton Police Department.

His case remains open under suspicious circumstances.

Last Seen: Jun 2, 1991
