Question:

Does anyone know of any american art thefts?

This information is for my senior research paper...and i can't find much information on this besides the theft in Boston in 1990. If anyone has any information I would REALLY apprieciate it, even if it is just a resource. I'm also writing on European and Egyptian art thefts as well.....
Thanks!

I have heard about the theft of some artifacts from the archaeological site of Moundville in Alabama. Though the left occurred in 1980 it was not widely publicized until a few years ago.

The above is a link to a brief article. You should be able to find more information in a newspaper archive search. If you have time you might try contacting the researchers at Moundville. They tend to be pretty approachable and if they have the time they might be able to give you some more information.

And here is the University of Alabama's page about the theft.

If you're not already aware of it, the website for SAFE (Saving Antiquities for Everyone) http://www.savingantiquities.org/... has some good information as well.
