CSI: NY, Season 5

Sid:
(standing over a decomposed body) The last 15 overdose cases Pino worked. I had them exhumed.

Mac:
(taking a good look at the corpse) You're the doctor, but isn't this one a few organs short?

Sid:
Two kidneys, one bladder, and a liver to be exact.

Mac:
All the organs where narcotics naturally accumulate.

Sid:
And each of these bodies is missing the same ones.

Mac:
It appears as if Marty Pino was able to produce heroin by cutting out and processing key organs from his assigned overdose cases. He used his training and this place as his own personal heroin pipeline. Only after he lost his job and access to dead junkies, he resorted to murder. (camera pans back to reveal the room is filled with bodies)
