[The Complete First Season]
Almost every episode shows a flashback scene of what could have transpired that led to the death of a victim.
One example is the flashback of a man punching another man several times then stabbing him with a knife. The knife is seen jutting out of the man's chest with blood surrounding it. In that same episode, the murderer is shot in the leg by the police and brief blood spurting is seen. Another example is that of a woman who after strangling her sister, puts a rope around her neck to make it look as if she had committed suicide. There is a close-up of her legs convulsing briefly just before she dies.
On the whole, Season One features portrayals of violence that include some infliction of pain and injury but are never detailed, intense and/or prolonged.
The scenes of violence, while brief, contain some detail of the infliction of pain and depictions of injury.
