Express Kidnapping: The New Form of Unlawful Imprisonment - casoabierto.com Express kidnapping is a new method of criminal restraint used by bands of sicarios in the service of mafia networks. In express kidnappings, the victim remains only a few hours in the hands of his or her captors. Generally, the kidnappings are executed by small groups of delinquents, composed of two or three individuals, who hold the victim captive for no longer than 48 hours. This is because they lack the infrastructure necessary for carrying out traditional kidnappings.
