NCIS Season 7 Episode 6

Ducky suspects everything was staged, with forensic expertise, when retired NCIS agent Mike Franks's boat, still registered in donor Gibbs's name, hits a Navy ship, carrying the corpses of dishonorably discharged crooks Roy Keenan, US Army, and US Navy lieutenant Calvin Thomas Blanchard. They asked for Franks at his Mexican home, but no connections between them and Franks are known. The two met when in retired Colonel Merton Bell's PMC ('private military company'), the largest in Iraq. Franks turns up as well as his family's Iraqi matriarch.
