Art Imitates Life (S09E03)

This is a quirky episode where a twisted artist poses dead people as if they are still alive. He poses them at park benches, on cell phones standing at lightposts, and at bus stops. He is a disgruntled struggling artist -- who also happens to by a psychopath. The CSIs find him through the help of an eccentric artist played by Jeffrey Tambor. (CBS TV Network)
