Clark Preston

Clark Preston is an incidental character who appeared in A Thin Line as a dominant partner for Trevor Mills.

History
A businessman dealing with real-estate, Preston was greedy for money, which culminated in him formulating a scheme to create a crime wave he would gain money from when property values went down as a result, during 2002. He started by hiring Ronnie Green and Carlos Jackson to invade the home of Trevor Mills and his family. Green and Jackson did, and in the end, Trevor's father and sister were killed and his mother Pamela was raped and critically wounded to a near-vegetative state. Preston's scheme apparently failed when Green and Jackson were eventually caught and sentenced to life in prison for the crimes. He then started supporting Trevor and Pamela, and also gained money from the latter, who used her disability check to donate money. Meanwhile, Trevor began idolizing Preston to a point where he adopted his beliefs as his own.

Ten years after the Mills tragedy, Preston devised a new scheme to gain money and started a mayoral election campaign. He convinced Trevor to commit a string of home invasions and murders that seemed to be the work of gangs whose members were of ethnic minorities, to which he would use the crimes as arguments for his campaign. When the BAU is called in to investigate, they interrogate Preston after seeing one of his speeches to get rid of gangs if Trevor's murders are to be stopped. Told to stop promoting his arguments in order to stop the unsub from getting more inspiration, Preston turns them down and leaves, to which the BAU begin to suspect him of some sort of involvement. Preston later visits Trevor and Pamela, giving the latter flowers, and then tells Trevor that they need to "time their moves". Instead, an impatient Trevor kills another family the following night but leaves behind a witness.

Beginning to feel the heat, Preston tells Trevor to stay away from him. Meanwhile, Garcia finds out about Preston's involvement in the attack of the Mills family. When Trevor is killed by Morgan after he tries to kill Preston's rival candidate, Rossi and Hotch arrest him in front of his campaign staff as he constantly denies any involvement.
