NEW HAVEN, Conn. — The man accused of murdering a Yale lab technician last year will plead guilty, his attorneys said Tuesday.

Raymond Clark III, who entered a not guilty plea last year, will change his plea when he attends a scheduled court hearing Thursday, the Hartford Courant reported.

Annie Le, 24, a graduate student who went missing on Sept. 8, 2009, was found dead five days later behind a wall in a basement laboratory on Yale’s campus.

Clark, 26, is being held at a Connecticut prison on $3 million bail, the report said.
