'Person of interest' in Yale killing

HARTFORD, Conn. (AP) _ A Connecticut official says New Haven police have identified a ``person of interest'' in the death of a Yale University graduate student. The state official has firsthand knowledge of the police investigation in the death of 24-year-old Annie Le. The official spoke on condition of anonymity because the investigation in Le's killing is ongoing. A New Haven police spokesman did not immediately return a call seeking comment. Le vanished Tuesday from a Yale University research building. Her body was found five days later in a wall in the basement.
