Pastry DNA

May 31, 2007 (EASTPOINTE, Mich.) - Norman Wheeler's butt is going back to prison -- thanks to a bun.

The Detroit man has been sentenced to up to 90 months for a 2004 car theft. Prosecutors say the crucial bit of evidence was a partially eaten cinnamon bun, which had traces of Wheeler's D-N-A.

Wheeler had a D-N-A sample on file, because at the time of the match he was already serving a sentence for an unrelated car theft. He pleaded guilty last month in the latest case and was sentenced yesterday.
