NEW HAVEN, Conn. (CBSNewYork/AP) — An attorney for the animal research technician charged with killing a Yale University graduate student nearly two years ago said his client plans to plead guilty Thursday.

Public defender Joseph Lopez said Raymond Clark III, who was charged with strangling 24-year-old Annie Le of Placerville, Calif., would plead guilty Thursday in New Haven Superior Court. Lopez would not specify the charges, but said it was part of a plea deal.

Le’s body was found stuffed behind a research lab wall on the day she was supposed to get married in September 2009.

The 26-year-old Clark has pleaded not guilty to murder.

Police have said a green-ink pen under Le’s body had her blood and Clark’s DNA. Police said Clark signed into the secure building with a green pen the day Le disappeared.
