    A newborn baby was found dead in a ditch in South Dakota, but the case went cold. Then a detective picked up the case again 28 years after the crime, NBC News reports.

    "This case felt solvable, it always felt like we were so close," retired Sioux Falls Detective Michael Webb told NBC News.

    Ten years after he picked up the case, the baby's mother has been arrested and faces murder charges. The key was DNA and a searchable database that led to a match between the mother and the newborn.

    DNA technology company Parabon NanoLabs found two possible genetic familial matches using GEDMatch.com, a free open-source website that allows people to upload their genetic information retrieved from genetic testing companies like 23andMe and Ancestry to find other relatives or for research.

    [NATL] Clerk Pulls Out Machete on Would-Be Robber

    A would-be robber armed with a knife had a surprise in store when an Alabama store clerk pulled out a machete in defense. The two's brief knife fight was caught on camera before the clerk runs out to damage the robber's car.

    According to police, suspect Seth Holcomb walked up to the counter to make a purchase. He leaves the store and then comes back in as if to make a second purchase. Then, he pulled out a knife at the counter. What he didn't expect was that the clerk would pull out a machete of his own.

    Results from the open-source database together with old wedding and birth announcements allowed investigators to build "limited" family trees, eventually leading them to Theresa Bentaas — the baby's biological mother, who still after nearly four decades lived in Sioux Falls.
