    UNITED STATES of America, Plaintiff-Appellee v. Sidronio CASTILLO-OLASCUAGA, Defendant-Appellant
    No. 16-11807 Summary Calendar
    United States Court of Appeals, Fifth Circuit.
    Filed December 11, 2017
    Jay Stevenson Weimer, Assistant' U.S. Attorney, U.S. Attorney’s Office, Northern District of Texas, Fort Worth, TX, James Wesley Hendrix, Assistant U.S. Attorney, U.S. Attorney’s Office, Northern District of Texas, Dallas, TX, for Plaintiff-Appellee
    Rafael De La Garza, II, Esq., De La Garza Law Firm, P.C., Plano, TX, Hilda Morales-Hahn, Law Office of Morales Hahn & Associates, P.C., Dallas, TX, for Defendant-Appellant
    Before KING, ELROD, and HIGGINSON, Circuit Judges.
   PER CURIAM:

Sidronio Castillo-Olascuaga appeals the 127-month sentence imposed following his guilty plea conviction for conspiracy to distribute cocaine. He argues that the district court erred in applying a firearm enhancement pursuant to U.S.S.G. § 2Dl.l(b)(l) because neither he nor his co-defendant possessed the firearm in question. We review the district court’s interpretation of the Sentencing Guidelines de novo and its factual findings for clear error. United States v. Trujillo, 502 F.3d 353, 356 (5th Cir. 2007).

Though nothing in the record links the firearm to any particular conspirator, “the evidence makes it plausible that a ‘weapon was present’ and that one of the conspirators possessed it.” See United States v. Rodriguez-Guerrero, 805 F.3d 192, 196 (5th Cir. 2015) (citing § 2D1.1(b)(1), comment. (n.11(A))). As there was enough evidence to support that the weapon must have been possessed by one of the conspirators in furtherance of the conspiracy, the district court did not err .in its factual findings or legal conclusions underlying the firearm enhancement. See id.

Castillo-Olascuaga’s opening brief does not address his objection before the district court concerning the availability of a safety valve adjustment. The Government argues that Castillo-Olascuaga has waived the issue by failing to brief it. Castillo-Olascuaga replies that the issue is not ripe for our review because it was never ruled upon by the district court. At sentencing, the district court noted the objections based upon the firearm enhancement and the availability of the safety valve, overruled the objection to the firearm enhancement, and stated that, as a consequence, Castillo-Olascuaga was not eligible for the safety valve. As the district court ruled on the safety valve issue and Castillo-Olascua-ga does not provide any argument or analysis on that issue, it is abandoned. See United States v. Scroggins, 599 F.3d 433, 446 (5th Cir. 2010). The district court’s judgment is AFFIRMED. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
