Oh. Oh god.
Okay, so bear with me.
Many years ago, some friends and I worked at the University Museum of Archeology and Anthropology at University of Pennsylvania. At the time of this story, the museum was undergoing a bunch of renovations. The renovation dust would intermittently get kicked up by the ventilation system or would fall in a clump or whatever, and the movement would set of the security alarms. After a couple months of this, Security became somewhat lax in responding to alarms, because every night there were a number of false alarms.
So, one early morning, a student is walking to the university and spots something weird sitting in the middle of the pedestrian walkway on the South Street bridge. As they get closer, it starts to look familiar. They get up close and recognize it as the solid silver stand that usually supports 
in the Rotundra of the Museum. This is the first indication that anyone has that the museum was burgled the night before.
The police are called, the stand goes through evidence collection, everyone traipses over to the Museum, Security (and the museum administration) is shocked. Everyone starts looking around for whatever else might have been taken. Eventually we conclude that only three items are missing: the Dowager Empress' crystal ball, the solid silver stand the ball usually rests on, and a 2500 year old bronze statue of the Egyptian god Osiris. [The ball is gorgeous: it's like the third largest crystal ball in the world, it's absolutely flawless, and John Wanamaker bought it for like $50,000 back in 1920.]
All three items were taken from either the Rotundra itself or just nearby. This is somewhat confusing, as the Rotundra is all the way toward the back of the Museum, and up a couple staircases. Why wouldn't the thieves grab stuff from a more accessible area instead of crossing almost the entire Museum? Also, the objects are heavy or difficult to carry - why wouldn't they take something smaller, more easily portable, and more valuable - for example, the Tang dynasty horses that are also in the Rotundra and much more valuable?
Even more confusing is why the thieves decided to ditch the stand for the crystal ball. Presumably they were having problems carrying all three items and decided to leave one behind. Did they drop the four-foot tall 60-pound statue of Osiris? No. Did they leave the 50-pound crystal ball which is very round and can be hard to hold safely? No. They decided to leave behind the 20-pound stand, which has lots of easy finger-holds, is made of solid silver, and is easily meltable into easily-sold unidentifiable metal. It's all just ... very weird.
Anyway, the police show up. Because of some University association with the state that I can no longer remember, the FBI shows up. There's lots of chaos. And ... nothing happens. The FBI takes the stand into custody for forensic examination, but they can't find any clues. They keep the stand in custody for a couple years in case "something else turns up" but the case goes cold.
Eventually they return the stand to the Museum. We clean it carefully and, heartbroken, put it into storage. And for a couple more years, nothing happens. [continued]
