MEMORANDUM **

Joshua Cabillo, a South San Francisco Police officer, shot and killed fifteen-year-old Derrick Louis Lamar Gaines (“D.L.”). D.L.’s parents, Rachel Guido and Derrick Lamar Gaines, filed a 42 U.S.C. § 1983 action against Cabillo; the suit was later settled. After the parents’ suit was filed, but before the settlement, Dolores Piper also filed a pro se § 1983 action against Cabillo, seeking damages as D.L.’s “surviving great aunt and legal guardian.” Cabillo moved to dismiss, arguing that Piper lacked standing to seek damages for loss of familial relationship. Piper did not oppose the motion or request leave to amend her complaint. The district court dismissed Piper’s complaint with prejudice. We have jurisdiction over her counseled appeal under 28 U.S.C. § 1291 and affirm.

1. Although § 1983 allows a parent to reqover damages for the state’s interference with the “constitutionally protected liberty interest in the companionship and society of his or her child,” Kelson v. City of Springfield, 767 F.2d 651, 655 (9th Cir. 1985), this right does not extend to other family members, such as great aunts, see Ward v. City of San Jose, 967 F.2d 280, 283-84 (9th Cir. 1991), as amended on denial of reh’g (June 16, 1992), or “creature[s] of state law,” see Backlund v. Barnhart, 778 F.2d 1386, 1390 (9th Cir. 1985) (quoting Drummond v. Fulton Cty. Dep’t of Family & Children’s Servs., 563 F.2d 1200, 1207 (5th Cir. 1977)), such as legal guardians. Piper’s complaint therefore failed to state a claim upon which relief could be granted.

2. The district court did not abuse its discretion in denying Piper leave to amend to clarify her relationship with D.L., as *508 any amendment “would be futile.” Saul v. United States, 928 F.2d 829, 843 (9th Cir. 1991). Piper asserts that she raised D.L. when his biological parents would not take responsibility for him, but the constitutionally protected liberty interest of parents in relationships with their children is not obviated by the weakness of the relationship. Santosky v. Kramer, 455 U.S. 745, 753-54, 102 S.Ct. 1388, 71 L.Ed.2d 599 (1982). Nor can Piper allege facts (such as an adoption) establishing that she legally supplanted the parents’ familial interests. See Smith v. Org. of Foster Families for Equal. & Reform, 431 U.S. 816, 846-47, 97 S.Ct. 2094, 53 L.Ed.2d 14 (1977) (explaining that “[wjhatever liberty interest might otherwise exist in” a non-biological “family-like” relationship “must be substantially attenuated” when the alternative is vindicating the right of a biological parent). Although we today assume without deciding that a non-biological non-adoptive “parent” could, under some circumstances, recover under § 1983 for loss of familial relations with a child, we cannot find such standing in a case in which the biological parents have already vindicated identical rights against the same defendant.

AFFIRMED.
