A defender of Lucy Letby was motivated by a sexual attraction to "pretty young blonde females", a key witness who was central to her conviction has suggested.
Dr Dewi Evans, 75, took aim at a statistician who questioned him in an attempt to pick holes in his testimony that led to the neonatal nurse, 35, receiving multiple life sentences for the murder and attempted murder of babies.
The Letby backer, who has remained anonymous due to the nature of his work, took to triedbystats.com to challenge the paediatrician on the quality of his evidence.
In response, Dr Evans said: "You seem very intense, and it's not unusual for men to have the hots for pretty young blonde females.

"A nursing uniform is a turn-on for some by all accounts. I would suggest you need to get out more, find yourself an available pretty young blonde female, with/without nursing credentials. But one who doesn't go to work intent on murdering her patients."
The pro-Letby campaigner subsequently attempted to justify his position, arguing that Letby was innocent.
He told The Mail on Sunday: "When I first heard about Letby's conviction, I had assumed she was guilty. I don't believe that anymore. This has nothing to do with her appearance but everything to do with the trial transcripts I've since read.
"Since the trial, an overwhelming number of highly qualified medical experts have described Dr Evans' evidence as absurd theories. But the most absurd of all is the idea that any questioning of the verdict is motivated by Letby being a blonde nurse."
A pro-Letby campaign called the nurse’s conviction “the biggest miscarriage of justice in British legal history” and this claim has been repeatedly contradicted by numerous experts and politicians.

Families of the victims have condemned attempts by Letby supporters to overrule the verdict, calling online rumours about its validity “hurtful and distasteful”.
She attempted to overturn her convictions twice last year at the Court of Appeal — in May and October — but lost both bids.
Letby, from Herefordshire, faces 15 whole-life orders after being found guilty of murdering seven infants and attempting to murder seven others between June 2015 and June 2016.
She carried out the attacks by whilst working at the Countess of Chester Hospital. Letby will never be eligible for parole and is expected to die behind bars.
