Three sources close to the investigation confirmed the discovery to Reuters Friday, nearly a week after Jack Carter Rhoad, 30, and brothers Callum, 33, and Jake Robinson, 30, were last seen in the province of Baja California.
They were enjoying a surfing vacation in the port city of Ensenada, just 80 miles south of San Diego, a trip they were documenting on social media until Saturday, when the posts mysteriously stopped and they failed to arrive at an Airbnb.
