10 Grisly Unsolved Murders (PHOTOS)

To say that as a society we take an interest in murder is an understatement. From today's headlines to tomorrow's books, TV shows and movies, murder reigns supreme. And as if the more than half a million real-life murders a year around the globe (some 17,000 in 2010 in the United States alone) somehow constituted a lack of violent death, fiction novels add a never-ending supply of made-up stories of murder and mayhem to the count.

Among the most enduring murder mysteries are those that were never solved, those in which the perpetrators were suspected but never brought to trial, and those that ended in acquittal or mistrial, leaving the question, "Did someone get away with murder?"
