A former Yale University lab technician charged with strangling a graduate student and stuffing her body behind a laboratory wall appeared in court Tuesday, but did not enter a plea to murder.

Twenty-four-year-old Raymond Clark III appeared in an orange jumpsuit in New Haven Superior Court. He's accused of strangling 24-year-old Annie Le (LAY') of Placerville, Calif. His lawyers say he eventually will plead not guilty.

The judge scheduled a probable cause hearing for Oct. 20, in which sides will have the right to introduce evidence and call witnesses. Under Connecticut law, defendants accused of murder have the right to the hearing within 60 days of their arrest to decide if the case will go forward.

The judge said he will also consider at that hearing whether to extend a sealing order on the police arrest affidavit in the case.

Le was a pharmacology graduate student who vanished Sept. 8 from a Yale medical lab building. Her body was found in the building five days later, on what was supposed to have been her wedding day.

Police have not talked about a motive in the slaying, largely because Clark has not talked to authorities. Investigators and Yale officials have called Le's death a case of workplace violence, but have not elaborated.
