At about noon Sunday, October 23, the last survivor was pulled from the rubble; he was LTJG Danny G. Wheeler, Lutheran chaplain for BLT 1/8.[66] Other men survived beyond Sunday, but they succumbed to their injuries before they could be extracted from the rubble.[67] By Wednesday, the majority of the bodies and body parts had been recovered from the stricken barracks, and the recovery effort ended on Friday.[68][69] After five days, the FBI came in to investigate, and the Marines returned to normal duties.[69]
