Finally with the questioning of the experts evidence. I think it is important. If someone is told to look for evidence of a crime rather than to look for what caused a death the outcome has potential for bias. Hence the discrepancy between post mortem cause of death and prosecution witnesses cause of death. Also worth remembering that the prosecution wouldn’t put someone in the stand who didn’t agree with their proposed cause of deaths.
However, Dr Evans himself stated he wasn’t looking for a crime.
Dr Evans said he was tasked with investigating a "clinical condition", not a "crime", when he became aware of the Countess of Chester Hospital case, when tasked by the National Crime Agency.
He said the scenarios added up to a "constellation of worries" on what went on between June 2015 and June 2016.
He adds that in past cases, he has been brought in by police and the conclusion was accidental, so the case was closed with no further police involvement.
He is asked about his 'state of mind' in his approach to the cases.
"My state of mind was very clear - let's find a diagnosis. Nothing to do with crime. Let's identify any specific collapse, and see if I can explain it.
"There were occasions where I couldn't explain it, and occasions where I found something deeply suspicious.
"There were incidents I found disturbing."
He was asked to investigate 33 cases in total, with two insulin cases later.
He said there were two babies were born in unsurvivable conditions, with obvious medical diagnoses.
He said: "The name Lucy Letby meant nothing to me. I didn't know the staff.
"I was the easiest physician and the most difficult. I was a blank sheet of paper. I had no idea and relied entirely on the evidence I could see from the clinical notes and applying my clinical experience and forming an opinion to the cause."
He said he asked to have one case file to have "an idea" of what he was dealing with.
Mr Myers: "Was the phrase 'air embolus' used at all?"
Dr Evans: "No. The first person to use air embolus, as far as I was concerned, was me.
"I need to give the NCA a compliment, they never gave me a steer. They are good, professional people."
). I still don't like it though - I haven’t done anything wrong isn’t how I’d word things. I maintain that she couldn’t have written before her first arrest - I’m evil, I killed them on purpose, I’m a bad person and pay every day, I did it - if she was innocent.
I’m sorry but I think you’d recall this! Hardest thing I’ve ever had to do. Physically typed that the dad was on the floor crying. But three years later you have no memory, I don’t know how significant this is in terms of the case as a whole but it stood out to me and I say bullshit !!
she isn't even fat but she's terrible at her job
