Richard Gallegos, Jr. appeals the district court’s dismissal of his civil rights complaint for failure to comply with a court order to identify by name the Slidell police officers discussed in his complaint. Although the district court dismissed Gallegos’s suit without prejudice, the dismissal is effectively with prejudice due to the one-year statute of limitations. See Owens v. Okure, 488 U.S. 235, 249-50, 109 S.Ct. 573, 102 L.Ed.2d 594 (1989); Long v. Simmons, 77 F.3d 878, 880 (5th Cir. 1996); Davis v. Louisiana State Univ., 876 F.2d 412, 413 (5th Cir. 1989).

The record does not show that Gallegos’s failure to comply with the court’s order was the result of contumaciousness or an attempt to delay the proceedings. See Berry v. CIGNA/RSI-CIGNA, 975 F.2d 1188, 1191 (5th Cir. 1992). Additionally, Gallegos was likely entitled to conduct discovery to determine the identities of the unnamed defendants, as “[i]t is conceivable that” readily available documentation would reveal the identities of the officers who participated in the allegedly illegal arrest. See Murphy v. Kellar, 950 F.2d 290, 293 (5th Cir. 1992). Consequently, the judgment of the district court is REVERSED and the case is REMANDED to afford Gallegos the opportunity to conduct discovery.
