The former Yale lab technician charged with killing a graduate student last month is scheduled to appear in a Connecticut courtroom.

Raymond Clark III is due in New Haven Superior Court on Tuesday. His lawyer says he will plead not guilty after deciding whether waive his right to a probable cause hearing.

Police say Clark strangled the 24-year-old Annie Le (LAY') and hid her body behind a wall in the laboratory building where they both worked. Authorities have not released a motive.

People charged with murder in Connecticut have the right to a probable cause hearing, in which both sides can introduce evidence and call witnesses. A judge then decides whether the case can move to trial.

Le's body was found on what was to be her wedding day.
