Murder

Murder is a crime committed by a human being against another human being that causes death and is done with the intent to kill. In most countries, it is the most serious crime and is punishable by the highest available penalties, including the death penalty in extreme cases. A person who intentionally causes the death of another person is called a murderer, and the murdered person is called a victim. Murder may be carried out as an attempt, as an instruction, as an organizer, or directly as the perpetrator. The intent to murder is either direct or indirect.

Research into the behaviour of murderers, the motives leading to murder and other concepts associated with murder is dealt with from a psychological point of view by forensic (forensic) psychology.

A multiple killer is a killer who has multiple victims.

A Mass murderer is a killer who commits four or more murders in one incident, the murders are often committed in one location. An example would be suicide bombers.

Serial killer - murders in different locations at different intervals. Each crime is a separate piece of work, the killer can be active for a very long time (he does not stop killing by himself). The method of execution of the murder is the same.
