So the DNA match to the bottle found in his trash was not confirming she had been there but confirmed that he was the match to the DNA found on her underwear.
Sherri Papini's family issues statement following her arrest, charges she faked kidnapping
"The case finally broke in 2020, according to the complaint. When Papini was hospitalized in Woodland upon her return, investigators collected male DNA from her underwear and sweatpants that did not match Keith Papini's.
On March 19, 2020, the California Department of Justice's Familial Search Committee voted to release to investigators the results of a DNA search using that sample and matching those on file, according to the complaint.
The DNA came back as a "familial match" to a man who is referred to as "Person 2" in the complaint, and who had two living biological sons. One of them, the ex-boyfriend, caught their attention, according to the complaint, because he had shared a joint AOL email account with Sherri Papini and had conducted financial transactions with her.
In June 2020, FBI agents collected a discarded bottle of Honest Honey Green Tea from the ex-boyfriend's trash in Costa Mesa, the complaint said. The DNA at the mouth of the bottle, investigators said, was a match. That August, the investigators said they interviewed the ex-boyfriend and he provided extensive details that fit the physical evidence in the case and exposed Sherri Papini's story as a fabrication, according to the complaint."
