MEMORANDUM**
Agent Fox’s expert testimony on drug value did not explicitly or implicitly present a profile of a person in a drug trafficking organization, so this case is not affected by United States v. Vallejo,1 Nor *394did admitting Agent Fox’s testimony violate Federal Rule of Evidence 704’s prohibition on the use of expert testimony regarding mens rea, as Agent Fox did not testify or infer Martinez-Gareia’s mental state.2 The testimony bore on scienter and intent, entirely independently of whether Martinez-Garcia was acting alone or as part of an organization.
Because Inspector Abernathy’s testimony regarding alterations to the engine compartment were based on his direct observations and were within the purview of a lay person’s knowledge, his testimony was not undisclosed expert testimony.3 The district court did not abuse its discretion by admitting it.
As it relies on Harris v. United States,4 Martinez-Garcia’s challenge to the constitutionality of the drug statutes must fail because a panel of this Court already reaffirmed our prior holdings that these statutes are constitutional.5
