Martin Martinez-Estrada appeals his 130-month sentence imposed after his jury-trial conviction for possession, with intent to distribute, more than 100, but less than 1000, kilograms of marijuana, in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2. Martinez contends: (1) the district court abused its discretion by admitting alleged hearsay testimony of Agent Holguin, a member of the Drug Enforcement Agency Task Force, regarding a description of Martinez’ personal appearance; and (2) his rights were substantially affected by admission of this testimony because it improperly bolstered the testimony of his two co-defendants.

Hearsay is “a statement, other than one made by the declarant while testifying at the trial or hearing, offered in evidence to prove the truth of the matter asserted”. FedR.Evid. 801(c). Such testimony is generally not admissible as evidence, unless it falls within an exception. See Fed. R.Evid. 802. The district court’s evidentiary ruling is reviewed for abuse of discretion, subject to a harmless-error analysis. United States v. Crawley, 533 F.3d 349, 353 (5th Cir. 2008); see Fed.R.Evid. 103(a). In other words, an evidentiary-ruling error is reversible only where it substantially affects defendant’s right to a fair trial. Crawley, 533 F.3d at 353; Fed.R.Evid. 103(a).

The district court did not abuse its discretion in admitting Agent Holguin’s testimony. The Government asked Agent Holguin to testify specifically about information he provided to another law enforcement agent during the course of the investigation. The information relayed was based on details provided during interviews of Martinez’ co-defendants and included: a description of Martinez as wearing a black T-shirt and camouflage trousers during the commission of the crime, and having a distinctive tattoo around his right eye. The description was not offered to prove the truth of the matter asserted, but rather to explain how Agent Holguin proceeded in the investigation. Out-of-court statements, offered to provide background information to explain the actions of investigators, are not hearsay. United States v. Dunigan, 555 F.3d 501, 507 (5th Cir.), cert. denied, — U.S. —, 129 S.Ct. 2450, 174 L.Ed.2d 240 (2009).

In any event, any error was harmless because admission of the testimony did not substantially affect Martinez’ rights. See id. at 509 (holding prosecutor’s statements did not substantially effect defendant’s right to fair trial). The record is replete with evidence of the description co-defendants provided to Agents regarding Martinez’ appearance, including the testimony of two co-defendants who explained the descriptions they provided to agents. Furthermore, the record reflects additional, overwhelming evidence of Martinez’ participation in the drug venture: two co-defendants testified Martinez was one of seven men recruited to transport marijuana into the United States from Mexico, carried one of the bags containing a substance confirmed to be marijuana, acted as a translator for the non-English speaking participants, and even made some of the decisions during the trip.

AFFIRMED.
