Police said a Higganum couple told them they were spending time with relatives in their home when a family member went inside and found a credit card on the stairs, The Hartford (Conn.) Courant reported Monday.
Investigators said they found Walker Bruce, 45, asleep in a bedroom. Bruce told them he had mistaken the house for a bed and breakfast and left his credit card on the stairs as payment.
Police said Bruce appeared disoriented and is believed to have been under the influence of drugs.
Bruce was charged with third-degree burglary and taken to Middlesex Clinic in Essex for examination.
