NEW HAVEN, Conn. (AP) - A Yale lab technician appeared in court and was charged with murder Thursday hours after his arrest in the killing of a graduate student in research building where they both worked - perhaps sometimes in conflict.
Raymond Clark III, 24, kept his head bowed during the three-minute appearance in the suffocation death of Annie Le, also 24. He didn't enter a plea and said, "Yes, your honor," when asked whether he understood his rights. The judge then set bail at $3 million.
People interviewed by police have painted Clark as a "control freak" who viewed the laboratory as his territory, and authorities are investigating whether that led to the killing, according to a law enforcement official who spoke on condition of anonymity because the probe continues and many details remain sealed.
Investigators are having a tough time identifying a motive because Clark won't talk to police, the official said, noting that authorities don't necessarily need a motive because they have strong forensic evidence.
