Inmate Ashaunti Quantay Prowell appeals the district court’s 1 order granting defendants’ motions to dismiss his 42 U.S.C. § 1983 action for failure to state a claim. Having reviewed the issues raised in Mr. Prowell’s brief, see Blakley v. Schlumberger Tech. Corp., 648 F.3d 921, 933 (8th Cir. 2011) (issue is waived when not presented in brief with some specificity), we find that his complaint was properly dismissed for the reasons cited in the district court’s thorough analysis, see McAdams v. McCord, 584 F.3d 1111, 1113 (8th Cir. 2009) (reviewing de novo dismissal for failure to state claim, accepting as true all factual allegations, but not legal conclusions couched as factual allegations); Stone v. Harry, 364 F.3d 912, 914 (8th Cir. 2004) (pro se complaints are liberally construed, but must allege sufficient facts to support claims advanced). The district court is affirmed. See 8th Cir. R. 47B.
