MIDDLETOWN, Conn. Police say they've executed search warrants on a person of interest in the slaying of 24-year-old Yale graduate student Annie Le.
Investigators in the case of a slain Yale graduate student had been at the home of Raymond Clark earlier Tuesday.
Police discovered Le's body on Sunday in the basement of a research building at Yale's medical school, five days after she vanished.
A state official with firsthand knowledge of the police investigation says Clark is a "person of interest" in the case. The official spoke on condition of anonymity because the investigation in Le's killing is ongoing.
Investigators have interviewed about 150 people in the case but have provided little information, other than to rule out a student was involved.
