The battle between ex-con turned gumshoe Barry Minkow and multi-level marketing company USANA Health Sciences, Inc. (NASDAQ: USNA) continues. A couple weeks ago, I spoke with Minkow about his efforts to discredit the company, and the company's subsequent decision to file a lawsuit against him. Minkow carried on today, releasing a press release questioning the academic credentials of a Usana director/spokesman, and posting a video on YouTube where he visited a handful of retail vitamin stores to compare the prices of Usana's products to those of other brands. From the press release:

"According to Barry Minkow, independent licensed private investigators who specialize in examining resumes could not confirm that Mr. Waitley had earned a M.A. degree from the Naval Post Graduate School, in Monterey, California. Moreover, the Doctorate, or a Ph.D. in Human Behavior from La Jolla University listed in Mr. Waitley's resume, appears to have come from a now defunct and never-accredited "diploma mill," according to Minkow. Both alleged degrees are listed on official S.E.C. filings...

"In other developments, the second segment of the FDI response to Usana has been posted on YouTube.com. In this segment, Barry Minkow brings a film crew to four vitamin stores and purchases numerous vitamin products to compare prices with Usana's top selling, Usana Health Pak 100(TM), which wholesales for $118.00 for a one-month supply. "There is no objective, rational person who can watch this segment and conclude that, compared to comparable vitamin packs sold in retail stores, that the Usana product offers the consumer with any savings whatsoever - but is actually hopelessly overpriced when compared with multiple products from different companies."

When I spoke with Barry Minkow about the new developments, he referred to a "smoking gun." I am inclined to agree. So far, the Fraud Discovery Institute has uncovered that the company's CEO became a resident of Lichtenstein to avoid taxes and uncovered evidence that a key director falsified his educational credentials. Unless Usana can come up with compelling rebuttals, investors have to ask: What else is Usana hiding?
