- "Wonder what Ducky would say to this piece of work?."

Brett Evans was a Navy Chaplain assigned to the Norfolk Naval Base and who was later revealed to be a serial killer responsible for the deaths of numerous female Navy personnel.
Not much is known about his early life but it's presumed that due to the profile that Caitlin Todd composed on him, Evan suffered horrific abuse at the hands of both of his parents which prompted him to develop an unhealthy relationship or rather obsession with getting the perfect woman for himself.
At some point, he began abducting various women in the hope that they would fit his ideal match of a wife but when they didn't, he abandoned the building they were in while also taking the wedding ring he had given the previous victims and ensuring his tracks were covered, took great lengths to remove his fingerprints.
His latest victim, Petty Officer 3rd Class Carolyn Figgis who was found at an abandoned house scheduled to be destroyed prompted NCIS to be called in to investigate her disappearance and eventual death.
The team soon discovered that another Petty Officer 2nd Class named Barbara Swain had vanished without a trace, resulting in them heading to Jacksonville, Florida to talk about the case with NCIS Agent Jane Melankovic and also find the missing Petty Officer.
Unfortunately, realizing that he had been caught, Evans chose to kill himself by shooting himself in the head in the chapel when Gibbs and Kate attempted to confront him, presumably due to the fact that Evans preferred death rather than be arrested and end with either a death sentence or life imprisonment while also receiving a dishonorable discharge.
However NCIS were successful in saving Petty Officer Swain although due to the fact that she had formed an emotional bond with Evans, she tried to kill Agent Anthony DiNozzo but Kate managed to get her to surrender, solving the entire case once and for all.
As the chaplain at both the Norfolk and Jacksonville Naval Base, Evans had access to numerous and potential victims, many of them female.
He would abduct his victims as they left for work and seal them in an air-tight bunker.
As a result, the cases regarding their disappearances would go cold rather quickly due to the lack of any leads. He would force the victims to wear a wedding dress and live in an environment where the 1950s were common but restrained their movement by forcing them to wear a shackle at all times. He often took photos as possible trophies for himself.
Once realizing that the woman in question would not fit the qualities needed to be his wife, Evans would forcefully remove the wedding ring which was a token of possible marriage and seal off the bunker before leaving for good.
As a result of the air supply being cut, the victims often slowly suffocated to death over the past few months with their skin being so deprived of any sunlight or air that their bodies would become mummified.
