Police officers who arrested Lucy Letby have claimed the twisted nurse was expecting officers to appear, describing her interview as chilling.
The serial killer was found guilty of murdering seven babies on Friday – making her Britain’s top child killer.
But Lucy’s heinous crimes were uncovered during a nearly 10-month trial that revealed she also attempted to kill six other newborns.
Now, Detective Superintendent Paul Hughes – one of the lead investigators on the case – said he believed the ailing nurse did indeed expect to be arrested.
Mr Hughes said Letby’s unusual but “controlled” behavior during police questioning raised suspicions she was expecting a visit from the police.
The Cheshire Police officer leading the inquiry said Letby seemed remarkably calm for someone first arrested.
“She was emotionless, she cooperated, she answered the questions,” he said in an interview with The Mail on Sunday.
Mr Hughes added: “It was surprising – this was someone who had never had anything to do with the police in their life.”
“She was arrested and held in custody for eight murders and six attempted murders. At no point did she seem to be struggling with anything. She was calm, she wasn’t a hindrance, she mastered everything, she was controlled.
And he claimed that Lucy apparently “accepted” that one day cops would be at her door.
The detective continued, “There was no banging on the table, at no point did she say, ‘They say these babies were killed.’ I’ve been taking care of these babies, go find the killer, that’s not me.”
“There was a lot of acceptance that eventually we would come and knock on their door.”
His colleague Detective Sergeant Danielle Stonier echoed those observations, claiming the twisted health worker was unusually calm and “emotional” when questioned.
she said MailOnline: “The Lucy Letby you saw in court was the Lucy Letby I interviewed.
“Their tone of voice, their approach to answering questions, even the pauses, were largely the same.
“Lucy Letby was calm, she was pretty cool, she answered the questions, she was confident in the answers. She talked but there was no emotion.”
Letby, 33, was questioned three times between July 2018 and November 2020, when she was finally charged.
She was interviewed for more than 20 hours.
DS Stonier said the “big moment” came when officers revealed to Letby the results of blood tests, which proved two of the babies eight months apart had been deliberately poisoned with insulin.
“She had little to no understanding of that,” Ms. Stonier added.
“I remember reading those results out loud, and I don’t think she knew what that meant.”
Ms Stonier added that Letby neither cried nor cried during the arraignment.
The detective sergeant said she “appeared calm,” adding that she had “the ability to mentally switch off, to detach just to get by.”
Described by police as “beige,” there was nothing spectacular about the nurse, which initially suggested she might be behind the murders.
But after January 2015, the number of infant deaths and catastrophic in-hospital collapses increased significantly, and the connections became clearer.
Counselors were concerned when they found that the condition of the children who died had “unexpectedly” worsened.
Even the collapsed babies did not respond to adequate and timely resuscitation.
Footage of Letby’s police questioning following her initial arrest in July 2018 was previously released.
In some cases, Letby reportedly took up to three attempts before she was able to kill some of her victims.
Following her arrest, police searched her three-bedroom home in Chester on July 3, 2018 and uncovered a startling amount of evidence.
The nurse had scribbled powerful notes in journals and on sticky notes, including one that read: “I’m bad, I did this.”
