Law & Order: Special Victims Unit: Season 11, Episode 6

Spooked

When a young couple is found murdered in the back of a padlocked truck, Detectives Benson and Stabler investigate the scene and link the male victim to a dangerous Mexican drug cartel. Benson and Stabler follow a lead to an abandoned drug den where they are surprised to see FBI Special Agent Dean Porter (Vincent Spano), who is separately working on the case. Porter tries to take over the investigation, but suspicion arises and the two continue the hunt for the murderer. Following their intuition, Benson and Stabler come across shocking discoveries, which lead them to believe this case is much larger than a mere drug-related murder.
