The boyfriend of a slain pregnant woman whose remains were found in Rehoboth, Massachusetts, appeared in court on Wednesday and was charged with murder.

Monteiro was nearly three months pregnant at the time, her family said, as previously reported by WCVB and WBZ. She had told a friend — one of the last ones to see Monteiro alive — that she was not feeling safe. "She was like 'I don't feel safe right now something's not right,'" the friend reportedly said, per WCVB.
