Marty Bennett

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.

Background
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 Deputy Owen McGregor, to whom he was extremely loyal to.

Angels
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 larger conspiracy to orchestrate the death of the current Sheriff, Peter Coleman, a plan Bennett was aware of. He later participated in 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 was innocent in the entire affair.

Demons
After the shootout ends with Mills being shot dead by Morgan, McGregor orders him, Vicky Lorenzana, and his other colleagues to kill the BAU.

Modus Operandi
Since Bennett hasn't been 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.

Profile
Bennett was never directly profiled by the BAU, since their profiles were more consistent with the ring of corrupt Deputies as a whole.
