No. 02-51026.

Summary Calendar

United States Court of Appeals, Fifth Circuit.

July 28, 2003.

*305Before REYNALDO G. GARZA, HIGGINBOTHAM, and BENAVIDES, Circuit Judges.

PER CURIAM.1

Doeur Son appeals the summary judgment dismissal of his § 1983 civil rights complaint. In the district court, Son alleged that while he was confined in the Travis County Jail as a pretrial detainee he was subjected to excessive and unnecessary force, unconstitutional conditions of confinement, and disciplinary action without due process. Son also alleged that he was denied medical treatment and library services, that he was confined to his cell twenty-three hours each day and that, because he was shackled while outside his cell, he was denied meaningful recreation time. He also claimed that the defendants opened correspondence containing confidential legal materials.

On appeal, Son does not challenge the dismissal of his claims against the defendants in their individual capacities. Furthermore, he does not challenge the dismissal of the claims against the defendants in their official capacities for their alleged acts related to Son being denied access to the library, denial of due process during disciplinary proceedings, and the opening of his correspondence with his attorney.

We will not raise or discuss issues that the appellant has failed to assert. *Brinkmann v. Dallas County Deputy Sheriff Abner,*813 F.2d 744, 748 (5th Cir.1987). Although we may liberally construe briefs to determine what issues are being presented for our review, issues not raised at all are considered abandoned. *Huckabay v. Moore,*142 F.3d 233, 238 n. 2 (5th Cir.1998).

As a result, our review is limited to the remaining official capacity claims against the defendants. According to Son, the defendants knew, or should have known, about the conditions of his confinement, which he contends amounted to cruel and unusual punishment. Son further avers that said conditions were a result of policies, practices and customs in place at the Travis County Jail.

We review a summary judgment dismissal using a de novo standard. *Olabisiomotosho v. City of Houston,*185 F.3d 521, 525 (5th Cir.1999). To defeat summary judgment, the nonmovant must set forth specific facts showing the existence of a genuine issue for trial. Fed. R. Crv. P. 56(e). The nonmovant cannot meet his or her burden with conclusory allegations, unsubstantiated assertions, or with only a scintilla of evidence. *Little v. Liquid Air Corp.,*37 F.3d 1069, 1075 (5th Cir.1994).

Son’s claims against the defendants in their official capacities are treated as claims against the county. *Bennett v. Pippin,*74 F.3d 578, 584-85 (5th Cir.1996). A municipality is hable under 42 U.S.C. § 1983 only if: (1) the municipality has an official policy, practice or custom that could subject it to § 1983 liability; (2) the official policy is linked to the constitutional violation; and (3) the official policy reflects the municipality’s deliberate indifference to the injury. *Lawson v. Dallas County,*286 F.3d 257, 263 (5th Cir.2002).

*306Son has failed to produce evidence of a policy, practice or custom of Travis County that caused the alleged constitutional violations. *See id*at 263. Son’s only references to a custom or policy are his statements that the conditions of his confinement were the policies of the Travis County Jail. Conclusory references to an alleged but unidentified policy are not sufficient to withstand summary judgment. *Little,*37 F.3d at 1075. Accordingly, the judgment of the district court is AFFIRMED.
