NCIS Season 4 Episode 22

Photographer Jackson Scott, who follows his other senses since he became blind, took a picture of a corpse everybody else passed by, Petty Officer Peter Lynn from military procurement, whose stomach content indicates the exact same last meal as the vomit left by the fatal stabber who probably only made it appear like a mobbing. Lynn was the object of a naval investigation for malversations. Lynn's colleague David Wong, whose car was at the restaurant where he last ate, is missing and gets found, hung by the neck: suicide or murder?
