2. ANNIE LE
One of the most heartbreaking crimes I’ve ever heard of. Annie Le (above) was a Yale medical student with a promising career in pharmacology ahead of her. In addition, her wedding was just a few days away when she disappeared. The day she vanished was a normal day, she went to Yale to attend a class before heading to her on campus research lab. When no one heard from her, it was eventually discovered that security cameras showed her entering the research lab, but not exiting.

Five days later, the day of her wedding, her body was discovered hidden inside the wall of her lab. A lab technician, Raymond Clark, had strangled her before hiding the body. He never gave a reason for the murder.
