Defense lawyer Michael Attanasio asked whether Price would be concerned if evidence were kept in a "private residence for six or seven years." Price danced around an answer by saying it "depends on what kind of sample."
Attanasio also posed a hypothetical: If he had a syringe with B12, used it, cleaned it out and then put in steroids, would the test reveal the B12?
Price said he didn't know.
Attanasio also made it clear that the experts couldn't say who, if anyone, used the steroids. The government will offer its evidence for that connection Friday, when forensic scientist Alan Keel, who was using terms such as "heterozygote" and "homozygote" as the clock approached 5 p.m., returns to the stand. He's expected to say Clemens' DNA was found on the materials McNamee saved.
