During his introduction, he was assigned to the Special Investigation Section (SIS) of the LAPD's Special Operations Bureau.
Character Information Edit
Before “White Lies, Part 2”, he had spent nearly six years undercover in the Zyklon Brotherhood as a SIS Detective, befriending members and trying to identify the person/persons in-charge. When the City of L.A. and the LAPD condemned the Zyklon's apartment complex, Wes attacked Lt. Flynn and got himself arrested in order to identify himself to the Major Crimes Division with the help of his supervising officer, Lt. Chuck Cooper. After this reveal, he was still returned to jail with his cover intact to intimidate a L.A. County Jail inmate who was working for the Brotherhood as a messenger to make him cooperate with the LAPD.
In “White Lies, Part 3”, Acting Assistant Chief Howard and Captain Raydor ordered Wes to break his cover to a Zyklon Brotherhood member and his "friend", who was being interrogated by MCD for the murder of Hai Sun. With Wes' help, MCD identified the locations where the Brotherhood was dealing drugs and they gained a written statement of the Brotherhood's operations and Jordan Graff's involment.
After the case was closed, Howard asked Raydor if it would be okay for her if Wes was to stay with the Major Crimes Division, as he needed to be assigned somewhere until he can testify against the Zyklon Brotherhood, which could take years.
In “Heart Failure”, it is shown that Lt. Provenza is not very fond of him, as their conversations are mostly one-sided and Provenza is somewhat unimpressed to his actions. Some of this passive aggression might be attributed to Wes' history in SIS and his undercover work being a reason he has learned to withhold information, which is now a bad thing considering he is part of a team and has to provide his superiors the info they desire, without having to read it in a report. This was confirmed in “Cleared History” when Lt. Provenza was talking to him outside the crime scene, wanting him to tell someone if he is doing something important because he is not working alone anymore but has a team.
In “Bad Blood”, after finding .22 caliber ammunition in a suspects home, the suspect returns and Wes, along with Det. Sykes and Lt. Tao, chase him. After the suspect crashes his vehicle and escapes on foot, the detectives move in to apprehend him. Wes angrily shouted "get down, get down asshole or I'll shoot you dead!" after which Lt. Tao had to order him to stand down, twice, because Wes argued that because they found ammunition at his house, he could be armed and should be dealt with before he could cause any trouble as he was physically very large and could have caused problems even for three officers. He was ordered to stand down and only shoot if there was a weapon pointed at them. After Tao confirmed he had no weapons and had handcuffed the suspect, Sykes called for an ambulance while glancing over to the agitated Wes, still holding his weapon and looking surprised and concerned of his actions himself. He eventually holstered his weapon, and with Tao, helped the suspect up and to the ambulance.
In “Shockwave, Part 1”, Wes angered Deputy Chief Winnie Davis by saying she wants to take the credit for the bombing investigation when it is eventually solved to further her chances of being promoted to Assistant Chief of Operations. While the rest of the Major Crimes Division thought the situation was amusing, Lt. Provenza noted afterwards that it probably wasn't a "great career move". This even caused friction between Wes and Capt. Raydor, as she wanted to know from Wes if that is how he is supposed to speak to commanding officers. In “Shockwave, Part 2”, when Acting Assistant Chief Howard returned to Los Angeles from a leadership conference, he shared with the Major Crimes Division that Davis was sent there to replace him, effectively removing her from the race to Assistant Chief. After this, Det. Sanchez joked with Wes about how he won't be directing traffic in San Pedro after all.
- Wes is the second person from the Special Investigation Section to be assigned to the Major Crimes Division, the first being Amy Sykes.
- Wes admits to Amy Sykes in “Dead Drop” that due to his undercover role, he was occasionally forced to do drugs. As a result, he can tell when a batch of marijuana is "very good" marijuana. Testing on the recovered drug bundle later confirmed Wes' assessment.
- Due to his time in the Zyklon Brotherhood, Wes is indicated to have gathered a great deal of incriminating evidence on the organization. Upon learning that Wes was an undercover cop, Patrick Cox stated that the Brotherhood was worse off than they thought if the police had Wes on their side and immediately made a deal. Wes is also stated to be a key witness in trials against Brotherhood members.
- While working undercover in the Zyklon Brotherhood, Wes was known by the nickname of "Cappie."
