Multiple bludgeonings, stabbings, shootings, etc. throughout the series, resulting in an abundance of bloodshed and gore.
All deaths involving being beaten with an object are shown offscreen, never showing the result of the attack.
Multiple people strangled
Mild to moderate violence with the death never being shown on-screen. People are beaten to death with a lamp, hammer, spanner and weight; no detail is ever shown as the deaths are always obscured. A man is hit in the head with a weight before having his head smashed with it, the second hit is offscreen with some blood splatter; a woman is killed with a car door but this happens below frame. One brief scene of a stabbing but this isn't shown at all.
TV-MA violence type: blood and gore.
