1. Who was behind the Seewen murders?
The killings took place during the Pentecost weekend of 1976, in a weekend house named “Waldeggli” located in a small allotment garden. The allotment garden stood in a protected forest in Seewen, Dorneck, Solothurn, Switzerland. Five were killed during 13 rounds of shooting with a Winchester rifle. 11 of the shots hit the head region of the victims while the other 2 shots landed in the chest region of the victims. Robert Siegrist, the son of two of the victims Eugen and Elsa Siegrist-Säckinger, wrote in his book Der Mordfall Seewen that one of the victims was shot four times in the hit, with each shot hitting the victim with precision.

Studies have shown that since the 1950s or 1960s numerous dogs have leaped from the bridge at the rate of about one dog a month. Dogs that leap over the bridge parapet fall 50 feet (15 m) onto the waterfalls below. Some dogs that survived this drop, and were then taken back to the bridge, have jumped again. The only linking factors for this unexplained event are that dogs mostly jump from the same side of the bridge, in clear weather, and they are breeds with long snouts.

The name Moonlight Maze refers to an incident in which U.S. officials accidentally discovered a pattern of probing of computer systems at The Pentagon, NASA, United States Department of Energy, private universities, and research labs that had begun in March 1998 and had been going on for nearly two years. Sources report that the invaders were systematically marauding through tens of thousands of files – including maps of military installations, troop configurations and military hardware designs. The United States Department of Defense traced the trail back to a mainframe computer in the former Soviet Union but the sponsor of the attacks is unknown and Russia denies any involvement. As of 2003, Moonlight Maze was still being actively investigated by U.S. intelligence.
