CASTLETON, Vt. (AP) — Students and residents in a small Vermont university town were being told to lock their doors and stick together as police searched Tuesday for a killer who shot a retired dean on her favorite walking trail last week.

Honoree Fleming, a retired dean and professor of education at Vermont State University in Castleton, was Thursday afternoon about a mile (1.61 kilometers) south of campus. Police said Monday they don't know if the community of roughly 4,500 people is in any further danger or whether Fleming was targeted.
