Ray Trapp was a Commander in the United States Navy and also the first victim of a terrorist.
Commander Ray Trapp's last assignment before his untimely death was to serve as the secondary handler charged with carrying protecting "the football," the case containing the launch codes for the United States nuclear arsenal.
Prior to Yankee White (episode) and a result of Major Timothy Kerry, the primary handler contracting a stomach virus and the flu as well, thus making him unable to carry out the mission, Commander Trapp stepped in, assuming Major Kerry's duties.
Commander Trapp was assassinated by a terrorist with suspected ties to al-Qaeda who used the venom of a Coastal Taipan, a deadly, poisonous snake found in Australia which was placed into the sleeves and cuffs of his uniform.
This later caused Commander Trapp to begin acting rather unusual than his current behavior while he suffered a fatal heart attack, immediately after dining with President George W. Bush aboard Air Force One.
The attack was triggered by the numerous emboli caused by the venom which blocked blood flow to the heart and caused Trapp to stroke.
After Trapp began seizing, Agent Caitlin Todd who had been talking to Trapp beforehand called for aid and the medics arrived straightaway, beginning their efforts to try and save Trapp while Burger, the head of the medical team along with William Baer went to make sure that the President who Trapp had been dining with beforehand had not been affected.
Despite attempts by the onboard medics to save him, Trapp died almost immediately.
After a lengthy battle between NCIS, the Secret Service and the FBI, his body later wound up in the possession of NCIS where the Medical Examiner, Dr. Donald Mallard conducted an Autopsy on the Commander's remains.
It was at first assumed that the death was natural but Abigail Sciuto found evidence suggesting it was a murder.
It is presumed after the investigation was wrapped up, Trapp's body was given to his family for burial.
