Annie Le murder: lab assistant Raymond Clark ‘failed polygraph’

Police investigating the murder of 24-year-old Yale University graduate student Annie Le, whose battered body was discovered on the day she should have been getting married, have raided the flat of a laboratory technician who had access to the building where she was found.

The official police line is that no arrest has been made. But anonymous sources have told local media in New Haven, Connecticut, where the Ivy League university is situated, that Raymond Clark III failed a polygraph test and was found to have "defensive wounds" on his chest.

Bloody items of clothing discovered behind a ceiling tile in the same building did not belong to Annie Le. Police are said to be investigating whether they belong to the lab assistant. Clark has not been charged with any crime, but he was led away in handcuffs by the police and has been described as a person of interest in the inquiry.

Annie Le was last seen alive on Tuesday, September 8 when campus surveillance cameras picked her up entering the medical school building where she worked as a pharmacologist.

After an extensive search, her body was found hidden in a cable duct in the wall of a basement laboratory. Access to the lab is strictly controlled, requiring a swipe card to gain entry.

The discovery was made on Sunday, the day she had been due to marry her fiance, Jonathan Widawsky, a graduate of Columbia University in New York. He is not a suspect.

As The First Post reported yesterday, Annie Le comes from El Dorado in California, by a twist of fate the same small county in the foothills of the Sierras where America's other big crime story has been playing out in recent weeks - the alleged kidnapping and rape by Phillip Garrido of Jaycee Lee Dugard. ·
