How did they obtain this DNA?
They got her DNA from her trash. Hope they got a search warrant.

Timeline:
The Winona County Sheriff’s Office announced an arrest in connection with the case on Thursday.
DNA technology provided by a nonprofit led investigators to a woman believed to be the baby’s biological mother, according to the criminal complaint.
The nonprofit, Firebird Forensics Group, then used DNA samples from the baby in an effort to find possible relatives with the help of voluntary DNA samples gathered by law enforcement.
That information led to a possible match between a mother and the baby. In May 2023, the DNA led investigators to Jennifer Nichole Baechle, 43, of Winona.
The criminal complaint that Winona County deputies then requested a DNA sample from Baechle, who then retained a lawyer.
Deputies then got samples of Baechle’s DNA by going through her trash and sent the samples to the Minnesota Bureau of Criminal Apprehension. Investigators then determined the infant found in 2011 “could be the biological child” of Baechle, the complaint states.
Winona County deputies then served a search warrant to collect Baechle’s DNA on March 19, 2024. Charging documents state the lab results showed the baby’s genetic results are “570,000 times more likely to occur in a biological child” of Baechle than someone unrelated to Baechle.
The complaint states the lab results show “very strong evidence to support” a biological mother-daughter relationship between Baechle and Baby Angel.
Firebird Forensics previously helped the FBI catch Joseph DeAngelo, who was otherwise known as the Golden State Killer.
