HARTFORD, Conn. (AP) Federal prosecutors say three men who stole at least $4 million in jewelry and watches after kidnapping two jewelry store employees have pleaded guilty to robbery and firearms charges.

Prosecutors said at least four men, two who were armed, broke into a Meriden apartment in April 2013, and bound and blindfolded four people. Two of the men then drove two victims to Lenox Jewelers in Fairfield, where the victims worked. Prosecutors said the robbers looted the store and left the two kidnap victims bound inside.

Twenty-seven-year-old William Davis of Allentown, Pennsylvania, pleaded guilty Monday. Twenty-eight-year-old Jeffrey Houston, also of Allentown, and 29-year-old Christopher Gay of Bronx, New York, pleaded guilty last week. They were arrested in May 2013. The men face up to 20 years in prison and millions in restitution.
