    UNITED STATES of America, Plaintiff-Appellee, v. Rodolfo POU, III, Defendant-Appellant.
    No. 06-11119
    Non-Argument Calendar.
    United States Court of Appeals, Eleventh Circuit.
    Nov. 8, 2006.
    Charles M. Harris, Ft. Myers, FL, for Defendant-Appellant.
    Peggy Morris Ronca, Jacksonville, FL, Karin B. Hoppmann, Tampa, FL, for Plaintiff-Appellee.
    Before DUBINA, WILSON and PRYOR, Circuit Judges.
   PER CURIAM:

Appellant Rodolfo Pou, III, appeals his conviction for manufacturing and possessing with intent to distribute, 100 or more marijuana plants, in violation of 21 U.S.C. § 841(a)(1), (b)(l)(B)(vii). On appeal, he argues that the district court erred by not holding an evidentiary hearing, outside of the presence of the jury during trial, to determine the voluntariness of his confession. Pou objected to the introduction of his confession during trial, but, he concedes that he did not file a pre-trial motion to suppress.

Rule 12(b) provides that a motion to suppress evidence must be made before trial. Fed.R.Crim.P. 12(b)(3)(C). Thus, we have rejected claims covered by Rule 12(b) when the defendant failed to preserve them by filing a pre-trial motion to suppress. See e.g., United States v. Nix, 438 F.3d 1284, 1288 (11th Cir.2006). Rule 12(e) further provides that “[a] party waives any Rule 12(b)(3) defense, objection, or request not raised by the deadline the court sets under Rule 12(c) or by any extension the court provides.” Fed.R.Crim.P. 12(e). However, “[f]or good cause, the court may grant relief from the waiver.” Id. We have stated that a “failure to present a suppression motion prior to trial constitutes waiver unless the district court grants relief for good cause shown.” United States v. Ford, 34 F.3d 992, 994 n. 2 (11th Cir.1994). Although the district court may grant relief from the waiver for good cause shown, we have declined to address the element of “good cause” when the defendant did not request relief from the waiver. See Fed.R.Crim.P. 12(e); United States v. Suescun, 237 F.3d 1284,1287 n. 7 (11th Cir.2001).

Because the record demonstrates that Pou failed to file a pre-trial motion to suppress his confession and did not even request relief from the district court for good cause shown, he has waived his arguments challenging the voluntariness of his confession. See Fed.R.Crim.P. 12(e). Accordingly, we decline to address the merits of Pou’s claim and affirm his conviction.

AFFIRMED.
