    No. 11-50550
    Summary Calendar.
    United States Court of Appeals, Fifth Circuit.
    Feb. 15, 2012.
    Bernice Marie Derouen, Lott, TX, pro se.
    Michael W. Dixon, Esq., Haley & Olson, P.C., Waco, TX, for Defendants-Appellees.
    Before JONES, Chief Judge, and HAYNES and GRAVES, Circuit Judges.
   PER CURIAM:

Appellant Bernice Marie DeRouen (“DeRouen”) attempts to challenge the district court’s dismissal for lack of jurisdiction of her § 1983 suit against a deputy sheriff and “the Sheriffs Department” of Falls County. The district court dismissed because she has already pursued — and lost — exactly the same claim in Texas state courts.

1. Under the Rooker-Feldman doctrine, she may not continue to litigate the claims by seeking review of the state courts’ decisions in federal court. The district court correctly dismissed on this basis.

2. Moreover, DeRouen’s initial brief on appeal utterly fails to address the Rooker-Feldman doctrine, and she has therefore waived any argument based on that doctrine. Brinkmann v. Dallas Cty. Dep. Sheriff Abner, 813 F.2d 744, 748 (5th Cir.1987).

The appeal fails to raise an issue of arguable merits and is DISMISSED as frivolous. See Fifth Circuit Rule 42.2. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cm. R. 47.5.4.
