(Newser) – If Ray Clark did, as police apparently suspect, kill Annie Le, investigators have an odd theory about his motivation, the New York Daily News reports. In emails that caught their attention, the Yale lab technician scolded Le about her lax handling of mice in the lab. Le apologized, but investigators wonder if resentment over the issue may have turned Clark into a killer. A co-worker described him to the New York Times as "very officious and very demanding" over minor issues and said he often gave grad students a difficult time.

Clark’s card swipe records reveal a meticulous worker who always took an orderly, logical path through the building. But on the day Le disappeared, his movements suddenly turn erratic, and he visits several places unrelated to his job—the pattern, perhaps, of someone looking to hide a body. Investigators are convinced forensic and DNA evidence will point to Clark, but until such proof arrives, he won’t be charged and remains free.
