duct an investigation of a police officer to the satisfaction of his supervisor. This reason is insufficient to call into question plaintiffs good name, reputation, honor, or integrity. See, e.g., Stritzl v. United States Postal Service, 602 F.2d 249, 252 (10th Cir.1979) (characterization of plaintiff as a slow worker with “poor work habits and low productivity” was not sufficiently stigmatizing to implicate a liberty interest); Hadley v. County of Du Page, 715 F.2d 1238, 1245 (7th Cir.1983) (mere charge of mismanagement was insufficient to give rise to a liberty interest claim), cert. denied, 465 U.S. 1006, 104 S.Ct. 1000, 79 L.Ed.2d 232 (1984).
Second, as to the April 30, 1981, suspension, plaintiff has failed to allege that the information contained in the letter of suspension was false. Plaintiff in fact conceded in his deposition that the suspension notice accurately indicated that he had issued some checks returned to the payee for insufficient funds. V R. 15. See Lentsch v. Marshall, 741 F.2d 301, 305 (10th Cir.1984); Williams v. West Jordan City, 714 F.2d 1017, 1021-22 (10th Cir.1983); see also Eames v. City of Logan, Utah, 762 F.2d 83, 85-86 (10th Cir.1985).
For these reasons, we agree with the district court’s holding that the suspensions did not deprive plaintiff of liberty interests to which the protection of due process could attach, and affirm that ruling.8
2. Property Interest
Relying on Umholtz v. City of Tulsa, 565 P.2d 15 (Okla.1977), the district court held that under state law plaintiff only had a “limited” property interest concerning his suspensions which was not protected by federal due process guarantees. II R. 751-53. Plaintiff asserts on appeal, however, that under cases such as Bell v. Board of School Commissioners, 450 F.Supp. 162 (S.D.Ala.1978), and Puckett v. Mobile City Commission, 380 F.Supp. 593 (S.D.Ala.1974), he had an unlimited property interest and was entitled to the safeguards of due process as a classified employee who could not be suspended except for cause. Plaintiff argues that Umholtz should not control here because the state court there failed to recognize that “[w]hile the defendant ... may elect not to confer a property interest in public employment, it may not constitutionally authorize the deprivation of such an interest, once conferred, without appropriate procedural safeguards.” Brief of Appellant 38-42.
At the outset, we agree with defendants’ contention that plaintiff’s property interest in his employment is created, defined and governed by state law. See Cleveland Board of Education v. Loudermill, — U.S. —, 105 S.Ct. 1487, 84 L.Ed.2d 494 (1985). We believe, however, that in light of recent Supreme Court decisions rendered after Umholtz, the district court’s summary judgment on this issue must be set aside.
In Umholtz, the Oklahoma Supreme Court had held that city employees in the classified service, who could not be suspended, demoted or removed from a position absent good cause, had only a limited property interest under a city charter provision permitting suspensions of ten days or less without a right of appeal. 565 P.2d at 23. The court relied on the plurality opinion of Arnett v. Kennedy, 416 U.S. 134, 94 S.Ct. 1633, 40 L.Ed.2d 15 (1974), to hold that “the provision granted a property right which was defined and limited by the procedural language of the provision” and

Plaintiff asserts in his brief on appeal that various news articles published in the City of Sand Springs newspaper contained “stigmatizing" statements made by defendant Kirk about the suspensions and demotion. Brief of Appellant 11. The text of these stories are not included in the record nor were they available to the trial court when it granted summary judgment for defendants. We, therefore, cannot consider plaintiffs contention that these articles establish a fact question which precludes summary judgment for defendants on the liberty interest claims. See Brown v. Parker-Hannifin Corp., 746 F.2d 1407, 1412 (10th Cir.1984) ("once a properly supported motion for summary judgment is made, the opposing party may not merely rest on the allegations in the complaint and must respond with some factual showing of the existence of a genuine issue of material fact”) (emphasis added).
