Diaz contends that the evidence was not sufficient to support the jury’s

verdict because the Government failed to adduce evidence that he knew about

the marijuana in the trailer. We will uphold the jury’s verdict if a reasonable

trier of fact could conclude from the evidence that the elements of the offense

were established beyond a reasonable doubt. Jackson v. Virginia, 443 U.S. 307,

319 (1979); see United States v. DeLeon, 247 F.3d 593, 596 n.1 (5th Cir. 2001).

Proof of involvement in a drug conspiracy requires evidence of “(1) the existence

of an agreement between two or more persons to violate the narcotics laws,

(2) the defendant’s knowledge of the agreement, and (3) the defendant’s

voluntary participation in the conspiracy.” United States v. Gallardo-Trapero,

185 F.3d 307, 317 (5th Cir. 1999). To prove guilt of possession with intent to

distribute a controlled substance, the Government must establish:

(1) knowledge, (2) possession, and (3) intent to distribute the controlled

substance. United States v. Solis, 299 F.3d 420, 446 (5th Cir. 2002).

The evidence showed that on May 27, 2007, at approximately 4:30 a.m.,

a tractor-trailer approached the border checkpoint near Sierra Blanca, Texas.

Diaz was driving the truck, and his brother Abel was a passenger in the truck.

A border patrol canine alerted to the presence of humans and/or illegal drugs in

the trailer, and upon further inspection, agents found a total of 3,405 pounds of

marijuana inside the trailer. Abel informed the agent that he saw the truck

loaded at 1:00 a.m. on May 27, 2007. Evidence demonstrated, however, that the

Diaz brothers were present when the truck was loaded with legitimate cargo on

May 25, 2007. The original seal on the trailer was intact; however, a bolt on a

door latch had been replaced. This alteration allowed access to the trailer

without damage to the original seal.

Testimony established that Diaz acted nervously during inspection of the

trailer at the border crossing. Diaz told Border Agent Velasquez that he was on

probation, stating that he had been arrested at a port of entry in El Paso for

entering with marijuana. Diaz explained that a friend had told him to cross a
No. 08-50685

truck through the port of entry in El Paso. He stated that he did not know that

there were drugs in that truck and that he could not believe the same thing was

happening to him again. Diaz stated that the people at the company must have

put the marijuana in the trailer. Customs Agent Patricia Hernandez confirmed

that Roberto Diaz had been stopped on January 31, 2006, at the Bridge of the

Americas port of entry in El Paso, Texas. The pickup truck he was driving had

19 kilograms of marijuana hidden in the engine compartment.

This evidence was sufficient for a reasonable trier of fact to conclude that

Diaz knowingly participated in the drug conspiracy and knowingly possessed the

marijuana with the intent to distribute. See Jackson, 443 U.S. at 319. Beyond

Diaz’s mere control of the tractor-trailer in which the drugs were found, there

were a number of circumstances from which the jury could infer guilty

knowledge. For example, border crossing agents testified that Diaz was nervous

when he was delayed at the checkpoint and that he seemed eager to leave. See

United States v. Gutierrez-Farias, 294 F.3d 657, 660 (5th Cir. 2002)

(nervousness). Moreover, there was evidence that Diaz had previously

attempted to cross the border with marijuana hidden in his truck. Id. at 661.

And Diaz possessed over 1,000 kilograms of marijuana, valued at $2.7 million,

which is unlikely to have been entrusted to an unsuspecting driver. United

States v. Garcia-Flores, 246 F.3d 451, 455 (5th Cir. 2001). Additional evidence

of Diaz’s guilty knowledge included: the delay between the time the computers

were loaded at TMX on May 25 and the time they arrived at the checkpoint on

May 27; Abel’s false statement that they had picked up the load only a few hours

before; and damage to the trailer doors, which was not observed by TMX

employees upon loading. See United States v. Gamez-Gonzalez, 319 F.3d 695,

699 (5th Cir. 2003) (noting that delay in arrival at checkpoint allowed inference

of guilt). Finally, Diaz’s ownership of five of the seven cell phones found inside

the truck also indicated his knowing involvement based on the DEA agent’s

testimony that drug traffickers often employ multiple cell phones. In sum, the
No. 08-50685

4

evidence was more than sufficient for the jury to infer Diaz’s guilty knowledge

beyond a reasonable doubt. 

Diaz argues that the district court improperly allowed testimony regarding

his dissimilar prior drug arrest in violation of Federal Rule of Evidence 404(b).

He argues that the Government bolstered its weak circumstantial case with this

evidence, that the testimony was not relevant because he denied knowledge in

the prior case also, that the prior arrest was too removed in time and was not

similar, and that the probative value was substantially outweighed by undue

prejudice.

Rule 404(b) prohibits the admission of “[e]vidence of other crimes, wrongs,

or acts . . . to prove the character of a person in order to show action in

conformity therewith. It may, however, be admissible for other purposes, such

as proof of motive, opportunity, intent, preparation, plan, knowledge, identity,

or absence of mistake or accident . . . .” Fed. R. Evid. 404(b). To be admissible,

extrinsic offense evidence must be “relevant to an issue other than the

defendant’s character,” and it “must possess probative value that is not

substantially outweighed by its undue prejudice and must meet the other

requirements of [Fed. R. Evid. 403].” United States v. Beechum, 582 F.2d 898,

911 (5th Cir. 1978) (en banc). We review a district court’s decision to admit Rule

404(b) evidence for abuse of discretion, with heightened review in criminal cases.

United States v. Pompa, 434 F.3d 800, 805 (5th Cir. 2005).

The testimony concerning Diaz’s prior arrest must be analyzed under Rule

404(b). See United States v. Gonzalez, 328 F.3d 755, 759-60 (5th Cir. 2003)

(analyzing admission of evidence of defendant’s prior conviction for possession

of marijuana under Rule 404(b)). Diaz’s plea of not guilty placed his intent at

issue for purposes of Rule 404(b). See Pompa, 434 F.3d at 805. Further, Diaz’s

own statements upon his arrest in this case that he had a prior arrest for

crossing marijuana, that he again had no knowledge of the marijuana, and that

he could not believe it was happening to him again, all placed his knowledge at
No. 08-50685

issue. The evidence of the prior arrest was probative of Diaz’s knowledge that

marijuana was hidden in the trailer. The fact that it was evidence of an arrest

and not a conviction does not make it inadmissible. See United States v.

Gonzalez-Lira, 936 F.2d 184, 189 (5th Cir. 1991). The date of Diaz’s prior arrest,

January 31, 2006, only one and a half years before this offense in May of 2007,

does not weigh against admissibility. See Gonzalez, 328 F.3d at 760 (holding

that admission of 1988 conviction to prove knowledge of drugs in 2001 offense

was not an abuse of discretion, and noting cases in which 15- and 18-year-old

convictions were admitted without an abuse of discretion). Although the

offenses were not identical in terms of the type of truck or the size of the load of

marijuana, Diaz’s own statements about his prior arrest for crossing marijuana,

volunteered by him at the time of this arrest, made this evidence highly relevant

as to his knowledge and mitigated any additional prejudice created by

presenting evidence of the arrest itself.

The district court gave instructions to the jury on the limited purpose for

which it could use the evidence of Diaz’s prior arrest. This also mitigated the

potential prejudicial effect of the admission of the evidence. See id. at 760 n.2.

The district court did not abuse its discretion in admitting this evidence.

AFFIRMED.
