Numb3rs Episode 4.12 Power

The team must track down a serial rapist, who is using his position as a police officer to ensnare his victims. The Los Angeles police department is immediately probed due to the location of the assaults, but the team rules them out after one of the victims points out that the rapist wore a different uniform. They track the uniform identified by the victim back to the Colina police department, and because they know that the assailant gave his victims a rare strain of gonorrhea, they are able to search Colina's hospital records for pharmaceuticals used to treat it, which eventually yields them the identity of the culprit.
