LaCombe practiced optometry as a sole proprietorship, LaCombe Eye Center. Slyfield worked for him at the front desk, but was not involved in bookkeeping. Over a four-year period, Slyfield embezzled checks made out to LaCombe by his patients, forged his signature, wrote her account number on it, and put the checks in her account at Bank One. LaCombe did not have an account at that bank. This worked for over 500 checks totaling $70,000 until discovered. LaCombe sued Bank One for negligence for accepting the forged checks for deposit and negotiation. The district court held for LaCombe. The bank appealed. Was it liable? [LaCombe v. Bank One Corp., 953 So.2d 161, Ct. App., La. (2007)]
