(AP) - Raymond Clark III appeared in court and was charged with murder Thursday hours after his arrest in thekilling of a graduate student whose body was found stuffed in thewall of the research building where they both worked.

Raymond Clark III, 24, kept his head bowed during thethree-minute appearance in the death of Annie Le, also 24. Hedidn't enter a plea and said, "Yes, your honor," when askedwhether he understood his rights. The judge then set bail at $3million and sent him to a holding cell.

New Haven Police Chief James Lewis said Le's death was a case ofworkplace violence and elaborated little except to say reports thatthe two had a romantic relationship were untrue "to myknowledge."

"It is important to note that this is not about urban crime,university crime, domestic crime but an issue of workplaceviolence, which is becoming a growing concern around the country,"Lewis said, adding he wasn't ruling out additional charges.

Clark's attorney, David Dworski, did not return calls seekingcomment. He has said Clark was "committed to proceedingappropriately" with police.

Clark was arrested earlier Thursday at a Super 8 hotel inCromwell, about 25 miles north of the Ivy League campus, where hegot a room shortly after being released from police questioning inLe's death.

Le was found dead on Sunday, her body hidden in the basementwall of a building where she worked as a medical researcher, on theday she was to marry her college sweetheart, Columbia Universitygraduate student Jonathan Widawsky. The Connecticut medicalexaminer said Wednesday that Le died of "traumatic asphyxiation."

Clark was under constant surveillance after he was released, andpolice spent Wednesday night and Thursday morning staking out theSuper 8 hotel where Clark was staying.

Shortly after 8 a.m. Thursday, police moved closer, shuttingdown the highway outside the hotel and blocking the road leadinginto the hotel as they made the arrest. Clark was wearing a whiteshirt with tan stripes and tan pants as police ushered him into theback of a dark sedan with tinted windows. The car then sped offtoward the highway, and arrived at the New Haven police departmentabout an hour later.

Richard Levin, the president of Yale, released a statementshortly after the arrest, saying Clark's employment history gave noindication he was capable of such a crime.

"This incident could have happened in any city, in anyuniversity, or in any workplace. It says more about the dark sideof the human soul than it does about the extent of securitymeasures," Levin said in a message sent to the Yale community.

The family of Le's finace, Jonathan Widawsky, said Thursday thatthey would not attend services for the "foreseeable future" attheir temple on New York's Long Island.

They said they want to "facilitate the safety, security andsensitivity" of services at Temple Beth El.

The family also thanked people who were involved in preparationsfor "a wedding that was not to be."

Clark's next court date is Oct. 6.
