As expected from a police and serial killer series, there are several murders and shootings throughout. Many dead bodies are found, and some of them are very disfigured and bloody; the murders are often discussed and referenced to, and most of them are grisly. The blood amount varies from mild to gory.
A man is seen chopping a chicken's carcass with a cleaver (graphic but brief).
In an episode centered on a sadistic serial killer of women, we hear about women being kidnapped, tortured and killed by a man.
In the third episode, a woman hits another woman hard in the face with a pan twice (the second time a lot of blood comes out of the wound and sprays on her hair, face, and neck); she falls on the floor, then the attacker releases her dog, who assaults and mauls the woman to death (offscreen but still very disturbing, we hear the dog barking and the flesh lacerating, while the woman screams and the other woman watches).
A man kills and threatens families after invading their houses. A woman is strangled on video. Later we see her bruised dead body (she has been beaten). Her two children have been killed too (we do not see their dead bodies, a man says their throaths have been slit). A man is killed offscreen; we later see his bloody body. Another woman has her wrist cut (she doesn't die), and her children are held hostage with a knife.
We see two girls in a process of "slave-making", being tortured while tied to a rotating structure (we also hear a creepy, menacing registration of the killer speaking). The first girl's husband is trapped and gagged inside a cage, witnessing his wife's torture; the killer tortures him as well, and we see him cutting one of his fingers (offscreen, blood splatters on the killer's face as the man screams). Afterwards he slices the man in the stomach, killing him (the slicing is offscreen, we see a large pool of blood on the ground). The killer then cuts his body into pieces with a saw (offscreen, we later see a few severed bloody pieces). In the tenth episode, the killer kidnaps a young man and cuts his tongue (the torture is not pictured); we see the victim tied to a bed, still alive, with his face covered in blood and the severed tongue nearby. Later the police finds his body, chopped to pieces on the bed; we see a severed arm. All these scenes are intense and disturbing. The killer is said to have kidnapped, tortured, and killed 19 men and 19 women in total (the women were also raped).

A car blows up with two people in it.
A man pushes a tied-up woman in a pit (we hear a loud thud - she is not dead).
A man hits a woman from behind, then pushes her in a coffin and locks her in (she is then released).
Two kids shoot birds; a dead bird is pictured. One of the boys finds the nest and smashes the chicks viciously (offscreen).
