Police say a U.S. Virgin Islands woman with a history of mental problems killed her 16-month-old son by stabbing him repeatedly with a pair of scissors.

Oakland Benta is the acting police chief on St. Croix. He told reporters a distraught 22-year-old island woman was found Thursday half-clothed and spattered with blood in her yard.

Benta says detectives later discovered bloody scissors and the stabbed body of her infant son inside the house. He was pronounced dead at the scene by paramedics.

Police did not immediately disclose the woman's name or any other details.
