Yep, it's like I remembered. Cheshire is very specific about there being no DNA on or in her that would indicate that CGM had sex. Thus the boyfriend's DNA was not found by the SBI.
I was agreeing with you right up to "thus".
If Cheshire said there was no evidence of her having had sex at all then either Joe Cheshire misinterpreted the results he was given by mistaking no match to the guys as meaning no semen at all in her, or he was spinning the results he was given, or he simply misspoke from a mindset of thinking in terms of the lax guys' jeopardy only.
ltc, the SBI results were announced on April 10. Nifong had a meeting with DNA Securities, the second testing entity the same day. The next day, the 11th, another meeting was held, and Mangum was called in to attend that second meeting with DNA Securities.
It looks to me like SBI did find the DNA in her, but obviously had no sample to compare it to except that of the players, to which there was obviously not match. The same day the results were officially back, Nifong met with DNA Securities, presumably about further testing, and Mangum attended another meeting with Nifong and DNA Securities the next day. So it also looks to me like Mangum was pressured at that time to give the names of the possible donors of that specimen.
Further, Cheshire said at the press conference, in answer to press questions, that two of the players DNA was found in the bathroom which is commonly expected, and that neither of those two matched the DNA found on the accuser, so he apparently had some idea that some unknown DNA had been found on her through the SBI testing.
