In an SBVT television ad, Dr. Lewis Letson asserted, "I know John Kerry is lying about his first Purple Heart because I treated him for that injury," but did not specify the alleged lie; he subsequently gave varied accounts of his purported interaction with Kerry. Kerry's medical records list a medic, J. C. Carreon, as the "person administering treatment" for this wound. Dr. Letson's name does not appear on the record, but Letson claimed it was common for medics to sign the paperwork even though Letson would treat the patient. That claim cannot be verified as Carreon died in 1992. In addition, Letson claimed he was given information by way of Kerry's crewmen who accompanied him to the clinic, but neither Zaladonis nor Runyon accompanied Kerry, nor has any crewman who was on the nearby Swift Boat supported this claim.
