With the development of computer and robotic science now machines are able to behave like human beings. Machines are to perform complicated tasks such as cognitive thinking, visual perception, speech recognition, and learning from past experience at a much higher speed and accuracy than human beings. This ability of a machine to behave like a human being in solving complicated problems is known as artificial intelligence (AI). There is increasing use of this technology in many fields. Government organizations and private companies use this technology to detect and prevent crimes. The idea of AI is also increasingly applied in the field of the criminal investigation. This enables meticulous crime investigation such as bloodstain pattern recognition and analysis, fingerprint analysis, DNA analysis, etc. Now complicated forensic findings are better understood. It helps in the 3D crime scene reconstruction also. Thus, in the coming days, AI technology will be very helpful for forensic scientists in a criminal investigations for a better legal administration.
