Bruce Kremen was six years old when he disappeared from a YMCA camping trip at Buckhorn Flat in the Angeles National Forest, California, on July 12, 1960. He was last seen playing with two other children near the campsite, about 300 yards away, and was noticed missing soon after he became separated from the group. A search was mounted in the rugged terrain, which includes cliffs and chasms, but no trace of Bruce was ever found.

Authorities initially considered that Bruce might have become lost or injured, but suspicion later shifted toward foul play. Serial killer Mack Ray Edwards, who confessed to killing several children in California in the 1950s and 1960s and claimed to have buried some victims under highways he worked on, became a prime suspect. Bruce’s case was reopened in 2007 and searches were conducted in locations tied to Edwards, yet no remains have been recovered.

Did anyone attend that YMCA trip or camp at Buckhorn Flat in 1960 who might remember Bruce or anything unusual that day?
