In criminal trials in Mississippi the prosecution may attempt to enter the alleged  confession of a Defendant into evidence.  However, the State has the burden of proving voluntariness of confession.  The burden is met by testimony of officer or other person 
having knowledge of facts that confession was voluntarily made without any threats, coercion, or offer of reward.

When objection is made to the introduction of a confession, the defendant is entitled to a preliminary hearing on the question of admissibility of confession; this hearing must be conducted in absence of the jury.

If the prosecution then makes out a prima facie case as to the voluntariness of confession, the Defendant must present testimony that violence, threats of violence, or offers of reward induced his confession.  The prosecution must then take testimony from all the officers who were present when the Defendant was questioned and when confession was signed, or give adequate reason for absence of any such witness.

If the Judge determines that the confession was voluntary, the confession is admitted into evidence and presented to the jury.
