(CBS/AP) PROVIDENCE, R.I. - A woman who died in a shooting at a Newport, R.I. antiques store threatened workers and stabbed one before apparently turning the gun on herself, police said Wednesday.

Authorities said 32-year-old Jennifer Allen arrived at Franklin & Co. Interiors Tuesday morning and confronted a 28-year-old woman with a handgun and large knife, reportedly telling her, "How do you want to die... pick one."

Allen, of Tiverton, R.I., stabbed Frances Pattavina of Newport twice in the torso and once in the head, but she was treated and released at Newport Hospital.

Authorities think Allen targeted Pattavina because she believed she was having an affair with Allen's husband, police told The Newport Daily News.

Pattavina told police that she knows Allen's husband but does not have a personal relationship with him.

Police Lt. William Fitzgerald said Allen apparently fatally shot herself in the head as officers entered the building owned by the International Tennis Hall of Fame & Museum, on a main street lined with boutiques and restaurants.

Wednesday's incident resulted in the lockdown of the nearby Hall of Fame and several other buildings in the seaside city famed for its mansions and music festivals.
