I’ve only tangentially heard about this, but another issue is that doctors in the US don’t have to, and aren’t encouraged to keep up with recent research.
Combine that with a medical education system that hasn’t changed drastically in 70 years to keep up with that new research and most US doctors are just out of date.
These people got caught because someone found their car and thus license plate.
Another had left a fingerprinted bottle that went missing when watching surveillance footage.
And then were able to confirm after finding the same outfit from the surveillance footage.
The lessons to be learned are to not use cars anywhere near the scene, leave no trace, fingerprints or digital evidence, including a phone, and make sure any recognizable clothing is well hidden, or even better thoroughly destroyed.
Oh and don’t post anything on social media.
