BURLINGTON, Vt. — A federal court magistrate said Tuesday the man charged with kidnapping a woman and her 5-year-old son last month outside the Mall of New Hampshire and later sexually assaulting the woman in Vermont must remain in custody.

Court documents show federal Judge John Conroy agreed with prosecutors who argued there was no way to protect the public and guarantee Everett Simpson, 41, would show up for future court appearances.
