Season 5: Episode 16 - No Good Deed

No Good Deed: When a human eyeball drops from the sky and into Stella's coffee, the CSIs find the eye belongs to a man’s body that is half buried in a balcony garden, being picked apart by talon-tagged buzzards. Suspicion falls on the victim’s wife, a Venezuela-born beauty who married the victim to obtain a green card. With the victim’s start-up tech company about to go public, his widow had everything to gain by his death. But when the widow’s brother calls 911, explaining the widow has been beaten within an inch of her life, forensic evidence tells a much more twisted story of greed and jealousy, involving the widow’s “brother” who is actually her lover.
