A makeshift memorial to Annie Le stands in the park across the street from the Yale University lab building where the graduate student's body was found Sunday.
News crews continue to stake out the complex, as staffers in white lab coats report to work there. Police aren't saying much, except to label it as a case of workplace violence. Raymond Clark is charged with murder. Police haven't offered a motive, but a law enforcement official tells The Associated Press a motive may not be needed at trial because there's an abundance of forensic evidence implicating the animal research technician .
Le's co-workers at the lab declined comment on Le or Clark, but a portrait of Clark is beginning to emerge. Speaking on condition of anonymity, a law enforcement official says police have been told that Clark was a "control freak" who clashed with scientists.
Yale President Richard Levin says Clark's employment history raised no suspicions. He says the incident could have happened anywhere, and speaks to what he calls the "dark side of the human soul."
