It is particularly odd when you look at his whole "origin story", as told on Panorama:
"One morning, I was at home, and I discovered this article about Cheshire Police investigating a neonatal unit regarding a lot of baby deaths. And I thought, “Hmm, that’s interesting. Sounds like my kind of case.”
I’d clocked up over 30 years’ worth of expertise and experience looking after sick babies. I had also clocked up several decades as a medical expert witness for the criminal court. I said to the police, “Let’s have a look at one case just to give me an idea of what’s going on.”
This particular baby was born in good condition, a good-sized baby, over two kilos, who had been stable but had suddenly collapsed. I saw these photographs of big, marble-sized blood clots under the liver, plus bleeding in the abdomen as well. But this looked awful to me. How on earth could a baby who was doing very nicely end up with serious liver abnormalities? And within a few hours, the baby was dead. I said to the police, “I want to look at all the case notes over this two-year period.”
But not the full case notes that might explain "how on earth" this happened.
Worth remembering that the pathologist in this case had already diagnosed liver hematoma, which is exactly what Professor Bennett described on radio 4.
That alone should have told Evans he needed to look at the obstetrics notes.
