Yale Killing: Bloody Sock, Pen Key to Case

An arrest warrant says DNA evidence on a bloody sock found in the ceiling and an ink pen found under the body of a Yale graduate student links an animal research technician to her killing.

The body of Annie Le was found stuffed behind a Yale research lab wall in September.

Authorities say in the warrant released Friday that the green-ink pen found under Le's body had her blood on it as well as DNA from suspect Raymond Clark III on its cap. Police say Clark signed into the secure building with a green pen on Sept. 8, the day Le disappeared.

The warrant says DNA from both Le and Clark was on the bloody sock found hidden in a ceiling.

The document also says Clark moved a box of wipes to hide that it had blood splattered on it.

A message was left for Clark's public defender Friday.
