A 37-year-old man faces an initial court hearing Monday in the stabbing death of a 51-year-old woman in the southeastern New Hampshire town of Danville.
Richard Moore faces a second-degree murder charge in the Sept. 2 death of Jo-Anne Boucher. He was arrested late Friday.
Moore also is on the New Hampshire sex offender registry, which has him living at the same address as the victim. He has a 1998 conviction for felonious sexual assault.
Neighbors said Moore had been staying with Boucher since sometime around March but no one knew there were problems until her death.
The attorney general's office would not comment on the connection between Moore and Boucher.
It could not be determined Sunday if Moore has retained a lawyer.
