From what you have written, the security officers who detained the minor presumably at a store for the alleged shoplifting violations are not law enforcement. The security guards are private employees and as such are not required to read anyone their rights per the Miranda decision.Given the situation that you have written about the minor and the shoplifting charge, I recommend that a criminal defense attorney be retained to assist in his or her defense.From what you have written, I do not see the criminal citation being dropped as the result of any Miranda right violation.
