Execution-style murder
（重定向自Execution style）
An execution-style murder, also known as Chicago-style murder and execution-style killing, is an act of criminal murder where the perpetrator kills at close range a conscious victim who is under the complete physical control of the assailant and who has been left with no course of resistance or escape. In this respect, an "execution-style murder" is similar to the usual meaning of execution, which is the taking of life by due process of law.
