A fine example of socialized/single payer health care.
Sounds more like a serial killer to me. Not the first of this style in the UK or USA.
There was one in the UK that tripled their homocide rate for one year because they counted all his murders in the year he was discovered. His thing was getting into their wills for substantial proceeds, then killing them. He was caught when he started faking wills.
And the USA has a problem with over prescribing opioid medicine as well, addicts from that is what is largely fuelling our heroin epidemic.
