Bennett in "Demons"

Deputy Marty Bennett was an accomplice of Owen McGregor and the lieutenant of a group of corrupt Sheriff's Deputies. He appeared in Season Nine of Criminal Minds.


Absolutely nothing is known about Bennett's background, other than he became a Sheriff's Deputy at some point of his adult life. Being corrupt, he became a member of a ring consisting of other corrupt Sheriff's Deputies, which was led by fellow Deputy Owen McGregor, to whom he was extremely loyal and eventually became his trusted lieutenant.

Season Nine

Angels (Part 1)

Bennett plays a minor role in the episode, assisting the BAU in their investigation into the killings of prostitutes, which was committed by other corrupt Deputies as part of a bigger conspiracy to orchestrate the death of the current Sheriff, Peter Coleman, a plan Bennett is aware of. He later begins the shootout between authorities and Christian preacher Justin Mills (whom the corrupt Deputies intended to frame for the killings but had to improvise due to the BAU's correct belief that Mills is innocent in the entire affair) after McGregor wounds Coleman, whom he later finishes off.

Demons (Part 2)

After the shootout ends with Mills being shot dead by Morgan, McGregor orders him, Vicky Lorenzana, Greg Baylor, and his other colleagues to kill the BAU. Bennett and Lorenzana pull Rossi and Blake over on a road located in the middle of the woods. As they prepare to kill the two in their SUV, they are struck by their SUV in return. McGregor arrives and asks them where they are; Bennett replies that the two agents escaped and then tries appealing to his superior. McGregor then shoots him and Lorenzana (killing the latter) in a fit of rage before shooting the police radio. As Bennett tries to crawl away while McGregor leaves, the latter shoots him again, this time fatally, before calmly walking away.

Modus Operandi

Since Bennett was never seen killing anyone, the term "M.O." is misused. However, he fired at Justin Mills and intended to kill Rossi and Blake by shooting them with his service pistol.


Bennett was never directly profiled by the BAU since their profiles were more consistent with the ring of corrupt Deputies as a whole. However, the lieutenant of the ring was described as appearing trustworthy but had the access and skill set to do a lot of damage; Bennett was deduced to be McGregor's lieutenant due to the power he imposed in his superior's absence.
