On March 17, 2011, lab technician Raymond Clark III pleaded guilty to the murder of Yale student Annie Le (pictured).
Clark killed Le in a research building on Yale's New Haven campus on September 8, 2009, and stuffed her body inside the wall of a basement laboratory.
Le's body was discovered on September 13, 2009, the day she was to be married.
Clark is serving a 44-year sentence in prison.
Le was the valedictorian of her high school and voted "most likely to be the next Einstein".
