Daniel McGowan appeals his convictions for importation of marijuana in violation of 21 U.S.C. § 952 and § 960, and for possession of marijuana with intent to distribute in violation of 21 U.S.C. § 841(a)(1). He argues, inter alia, that the district court erred in admitting expert testimony regarding the structure of drug trafficking organizations in a non-conspiracy importation case. Under the circumstances presented by this case, we conclude that admission of the testimony was error.
I
On July 2, 2000, Daniel McGowan drove a 2000 Ford Windstar from Mexico into the United States at the Otay Mesa Port of Entry, accompanied by a passenger, Mary Joanne Ramirez. While McGowan and Ramirez were waiting in the pre-pri-mary inspection area, U.S. Customs Canine Enforcement Officer Cagigas’s dog Spencer alerted to the gas tank of their vehicle by changing behavior and scratching at the tank. Officer Cagigas informed Customs Inspector Wilkins, who was working the primary lane, that Spencer had alerted to the vehicle. Inspector Wilkins then questioned McGowan. In response to Inspector Wilkins’s questions, McGowan stated that he was not bringing anything into the United States and had gone to Mexico to go to the mall. McGowan also stated that he was driving a rental car, had not lent it to anyone, had put a quarter tank of gas in the car earlier that day while in San Diego, and had filled the tank with gas a few times previously.
Inspector Wilkins escorted the vehicle and McGowan and Ramirez to the secondary lot where he conducted a more intensive inspection of the vehicle. Wilkins did not initially notice anything out of the ordinary about the vehicle or its gas tank. However, when he tapped the gas tank, he observed that it sounded hard, as if it
Subsequent investigation confirmed that McGowan had rented the vehicle from Enterprise Rental in La Puente, California on June 28, 2000 in the early afternoon. Border crossing information indicated that the vehicle crossed into Mexico later that afternoon, returned to the United States on the evening of June 30, and crossed back into Mexico on July 2 at 8:15 a.m. Receipts found on McGowan’s person at the time of his arrest indicated that he had purchased approximately fifteen gallons of gas from a San Diego gas station on June 28. Other receipts showed that he had made purchases from various stores in Tijuana, Mexico on July 2 between 10:51 a.m. and 12:55 p.m.
McGowan was subsequently convicted of importation of marijuana and possession with intent to distribute marijuana and sentenced to twenty seven months custody and three years supervised release.

Prior to the trial, McGowan moved
in limine
for the exclusion of expert testimony concerning the structure of drug trafficking organizations pursuant to Fed. R. Evid 401, 403 and 702, arguing that it was inadmissible under
United States v. Vallejo,
The district court denied the motion in limine, citing three reasons: (1) the expert testimony would be relevant on the issue of timing; (2) the testimony would explain why drug couriers “don’t fit the stereotypical, ‘Miami Vice’ type of concept of a drug dealer, driving fancy, expensive cars; that rather everyday people are used to bring the drugs across the border”; and (3) the testimony would be relevant to rebut defense arguments concerning the absence of fingerprints on the bags containing the drugs.
During the trial, Special Agent Villars of the United States Customs Service testified regarding the structure of drug trafficking organizations and the reasons that it would not have been useful for the government to fingerprint McGowan’s vehicle or the marijuana found there. Specifically, Villars testified that in a drug trafficking organization, each member has a specific duty, with the functions compartmentalized. Villars also testified that fingerprinting the marijuana packaging or the vehicle itself does not help track down perpetrators, because: the packaging used, as well as the presence of gasoline, makes it difficult to lift clear prints; any prints that could be lifted are likely to be those of the packager, not the driver; and
Ill
The admission of the expert testimony in this case was improper under
Vallejo,
The rationale provided by the district court, albeit without the guidance of
Vallejo,
does not justify a departure from
Vallejo.
The first reason — explanation of timing — is not relevant because the expert witness did not testify concerning the timing of the transaction, nor did the government argue the point. The second reason, dispelling the stereotype of typical drug couriers, was a rationale we have explicitly rejected as justifying admission of expert testimony in the government’s case in chief.
United States v. Beltran-Rios,
Further, contrary to the government’s assertion, defense counsel did not “open the door” to admission of the expert testimony at trial. The closest defense counsel came to asserting a lack of fingerprint defense was to question agents about whether they used gloves when examining the evidence. Thus, the issue was not affirmatively raised and was not at issue when the government expert testified. Allowing expert testimony based on an anticipation of a defense that the defendant has not yet asserted is improper.
United States v. Lim,
Finally,
United States v. Murillo,
IV
For these reasons, under the circumstances presented by this case, the expert testimony offered by the government should not have been admitted. Because reversal is required on this issue, we need not reach any other issue urged by defendant.
REVERSED.
