NEW HAVEN (AP) -- A former lab technician at Yale charged with killing a graduate student is scheduled to appear in court.

Raymond Clark III, of Branford, who is charged with killing 24-year-old Annie Le in September and stuffing her body behind a wall in a research building, is due to appear Tuesday in New Haven Superior Court.

Le vanished Sept. 8 from the Yale medical school research building where she and Clark worked. Her body was found five days later on what was to be her wedding day.

News organizations have asked a judge to unseal documents detailing the case. A prosecutor opposed the request, citing the privacy rights of the victim`s family and the need to ensure an impartial jury.
