Jeffrey Dahmer eerily took pictures of his victims after killing them, the new Netflix documentary series revealed.

Netflix released "DAHMER - Monster: The Jeffrey Dahmer Story" last month, which retells the story of Dahmer and his crimes. From 1978 to 1991, the infamous serial killer brought men to his Milwaukee apartment before killing and dismembering them.

According to Crime Museum, Dahmer's murders included "Rape, dismemberment, necrophilia, and cannibalism." After doing those things, the murderer took pictures of them.

In the Netflix series' first episode, the viewers discovered how Dahmer took polaroid photos of his victims in gory and horrifying states.

Biography.com explains the killer did it so he could see his victims "at various stages of the murder process, so he could recollect each act afterward and relive the experience." This was similar to the reason why he dismembered the bodies and kept them in places inside the apartment.

Meanwhile, ELLE Australia quoted the report shared by The American Journal of Forensic Medicine and Pathology, saying that the killing spree and taking pictures of the victims helped Dahmer to go through the negative feelings he had and keep himself company.

But little did he know, the pictures would eventually prove his guilt.

How Polaroid Pictures Helped Police Arrest Jeffrey Dahmer

Dahmer's intended victim, Tracy Edwards, became the key to his arrest after he managed to escape from the apartment. The handcuffed man went straight to the Milwaukee police and reported the man's crimes on Jul. 22, 1991, at 11:30 p.m.

At that time, he told the police that a freak kidnapped and handcuffed him. He then accompanied the authorities back to Dahmer's apartment.

Upon their arrival, the police already noticed an offensive smell and boxes of hydrochloric acid. They searched through the living space and the murderer's bedroom, where he reportedly hid the murder weapon.

In his drawer, the police discovered a knife and 84 polaroid pictures showing the victims' dismembered bodies.

When they arrested Dahmer, he reportedly told them, "For what I did, I should be dead." Aside from the polaroid cameras, Dahmer also took his victims' body parts as souvenirs.

Dahmer died years after his arrest after his fellow inmate at the Columbia Correctional Institution in Portage, Wisconsin, Christopher Scarver, beat him to death.
