ORDER DENYING DEFENDANT MARSHALL'S MOTION TO COMPEL  AND GRANTING GOVERNMENT'S MOTION FOR IN CAMERA INSPECTION 
Defendant Vine Richard Marshall has moved the court for an order compelling the government to provide discovery of three categories of documents: (1) agreements or understandings between the government and Arlo Looking Cloud about any benefit Mr. Looking Cloud may receive from the government in return for his testimony in Mr. Marshall's trial; (2) Arlo Looking Cloud's Bureau of Prisons central inmate file; and (3) any records from the Bureau of Indian Affairs, the United States Marshals Service, or any federal agency relating to any investigation, complaints, or sanctions concerning alleged misconduct, unprofessional conduct, or breach of ethical standards related to the personal relationship between federal investigator Robert Eccoffey and the government's cooperating witness known as "Maverick." See Docket 216. In the alternative, Mr. Marshall seeks an order requiring the government to provide these three categories of documents to the court for in camera inspection.
The government resists Mr. Marshall's motion. In response to category number three, the government provided Maverick's criminal history to the court for in camera inspection. Docket 244. Because the court was unable to ascertain whether the three categories of materials requested by Mr. Marshall contained Brady or Giglio material, the court issued an order requiring the government to submit the documents to the court for in camera review.*fn1 See United States v. Garcia, ___ F.3d ___, 2009 WL 996826, *4 (8th Cir. April 15, 2009).
Instead, the government filed a response stating: (1) that all documents relating to any agreement between the government and Arlo Looking Cloud concerning Mr. Looking Cloud's testimony have already been disclosed; (2) that the government does not have in its possession, nor has it reviewed, Mr. Looking Cloud's central inmate file; and (3) that the government has no evidence in its possession relating to any investigation, complaint, or sanctions concerning any alleged misconduct between the former United States Marshal and witness Maverick.
Evidence which is in the possession of police, though unknown to the prosecutor, may form the basis for a Brady violation. Youngblood v. West Virginia, 126 S.Ct. 2188, 2190 (2006) (citing Kyles v. Whitley, 514 U.S. 419, 438 (1995)). Thus, "the individual prosecutor has a duty to learn of any favorable evidence known to the others acting on the government's behalf in the case, including the police." Kyles, 514 U.S. at 437.
On the other hand, the government has no duty to seek out and provide discovery of evidence in the hands of third parties, even other government agencies, if those agencies are not acting on behalf of the government in the case. Id. See also United States v. Skorniak, 59 F.3d 750, 755-756 (8th Cir. 1995) (medical records); United States v. Dunn, 851 F.2d 1099, 1101 (8th Cir. 1988) (report written by a state child protection worker); United States v. Riley, 657 F.2d 1377, 1386 (8th Cir. 1981) (hospital records).
The court first notes that the government does not resist Mr. Marshall's motion for documents that reflect the agreement between it and Mr. Looking Cloud as to any benefit Mr. Looking Cloud hopes to gain by testifying at Mr. Marshall's trial. Instead, the government's position is that it has already provided Mr. Marshall with all responsive documents to this request. Accordingly, the court denies this request by Mr. Marshall as moot. According to the government's representation to the court, there simply are no other documents responsive to this request.
As to Mr. Marshall's request for Looking Cloud's central inmate file, that record would appear to be in the hands of the Bureau of Prisons ("BOP"). There is no suggestion that the BOP is acting on the government's behalf in this case in a role analogous to the police. The BOP is typically not a law enforcement investigatory agency, but rather fulfills a custodial role. In addition, the type of information Mr. Marshall seeks in Looking Cloud's central inmate file, information about substance abuse treatment or history or other avenues of cross-examination, has already been provided to Mr. Marshall through the discovery of a portion of Looking Cloud's presentence investigation report, which the court reviewed in camera before ordering the government to provide that document to defendants. Accordingly, the court finds that the government has no duty to seek out Looking Cloud's BOP central inmate file if it does not already have that document and, accordingly, no duty to provide it in discovery to Mr. Marshall. Kyles, 514 U.S. at 437. Mr. Marshall's request for an order compelling discovery of Looking Cloud's central inmate file is therefore denied.
The records pertaining to the relationship between Mr. Ecoffey and Maverick, and any disciplinary action arising from the existence of that relationship, is somewhat different. These records would be expected to be in the hands of the Bureau of Indian Affairs ("BIA"), Mr. Ecoffey's employer. The BIA, and Mr. Ecoffey as a BIA agent, played a key investigatory role in this case, assisting the United States Attorney's Office. However, the documents Mr. Marshall requests are not evidence of the crime with which he is charged, either inculpatory or exculpatory. Rather, the evidence Mr. Marshall seeks may or may not reflect on the credibility of the two witnesses, Maverick and Mr. Ecoffey. Furthermore, the key fact which has the possibility of reflecting on the credibility of the witnesses is the fact of the relationship itself, not any action that may have been taken by Mr. Ecoffey's employer when faced with evidence of the relationship at some later date. Clearly, Mr. Marshall and his lawyer are already apprised of the fact of the relationship itself and can cross-examine regarding that issue.
The Due Process Clause of the Fifth Amendment requires the government to disclose to the accused favorable evidence that is material to guilt or punishment and not otherwise available to the defendant. See United States v. Bagley, 473 U.S. 667, 678 (1985); Brady v. Maryland, 373 U.S. 83, 87 (1963). To prove a violation, the defendant must show that the evidence was both favorable and material, and that the government suppressed the evidence. United States v. Barraza-Cazares, 465 F.3d 327, 333 (8th Cir. 2006). The government has suppressed evidence when it was otherwise unavailable to the defendant, and the prosecution failed to disclose the evidence in time for the defendant to use it. Id.at 334. When Brady evidence is available to the defendant through other avenues, there is no Fifth Amendment violation if the prosecution fails to disclose the evidence. Bagley, 473 U.S. 678; BarrazaCazares, 465 F.3d at 334 (Brady violation is shown only when the materials were not otherwise available to defendant through other sources). Impeachment evidence falls under Brady when the reliability of a given witness may be determinative of a defendant's guilt or innocence. Giglio v. United States, 405 U.S. 150, 154 (1972).
Courts have rejected generalized demands for discovery of police personnel files absent some articulable reason for seeking such documents. See United States v. Lafayette, 983 F.2d 1102, 1106 (D.C. Cir. 1993); United States v. Andrus, 775 F.2d 825, 843 (7th Cir. 1985). However, such is not the case here, since Mr. Marshall seeks specifically-articulated information.
In United States v. Vue, 13 F.3d 1206 (8th Cir. 1994), the defendants argued on appeal that the trial court erred in denying their motion to compel the prosecution to obtain and disclose any information possessed by the Immigration and Naturalization Service relating to the existence of Ai and Bee Vang. Id. at 1208. A key issue in the Vues' defense was whether the Vangs really existed. Id. Thus, the Vues argued that the government's failure to seek out, obtain, and disclose the INS information that they argued would confirm the existence of the Vangs was a Brady violation. Id. The Eighth Circuit held that the Vues were required to show that the INS information was material to their defense before a Brady violation would be found. Id. "Materiality" in this context required a showing that, had the evidence been available, there ...
