In a statement, the families of her victims said they were heartbroken and thatjustice could not reduce the extreme hurt, anger and distress they had experienced. Lucy letby was also acquitted of two counts of attempted murder, and the jury were undecided on six charges of attempted murder. Today, the government has ordered an independent inquiry into the circumstances around this shocking case. 0ur north of england correspondent Judith Moritz is here with me. Youve been following this case throughout, judith, and its only now that the full scale of her crimes has become apparent. Yes, ican yes, i can tell you, reeta, that verdicts have been being delivered here at Manchester Crown court over several hearings over the last ten days. It was only today, when the jury days. It was only today, when the jury indicated they could go no further, that reporting restrictions were lifted and we are able now to report the full extent of what lucy letby has been found guilty of. That was an emotional moment in the court room, here in courtroom number seven, particularly, as you can imagine, for the families of those babies. Some of the jurors looked upset this afternoon, but conspicuous by her absence was lucy letby, who refused to come up from the cells. She wasnt in court. Its been fast moving ever since. The prosecution are considering a retrial on the undecided verdict here and there has been the announcement as you say of a government inquiry. She thought shed get away with it, but this was the moment the game was up. Hello, lucy, is it . My name is. With the cheshire police. Do you mind if i step in for two seconds . Yes. Thank you. Behind the door of this ordinary suburban house, britains most prolific baby killer was finally arrested, three years after her murder spree began. Just take a seat in. There for me, lucy. Ill move that seat forward a bit. Ive just had knee surgery. 0h, right, 0k. She worked here, on the Neonatal Unit at the countess of chester hospital. Her role to care for the most premature and vulnerable infants, but that couldnt have been further from her mind. The crying, ive never heard anything like it since. It was screaming. It was screaming, and i was like, whats the matter with them . Legally, we cant identify the families in this case, but their stories are distressing. These are the parents of twin boys born prematurely in 2015. Their mum was taking milk to them when she heard one of her sons crying loudly. He had blood round his mouth. And lucy was there, but faffing about and not really. Not doing anything. Lucy said, dont worry, the registrar was coming. And then she told me to go back to the ward. The babys mum left him in this Intensive Care area and went to call her husband. They thought their son was in safe hands with nurse letby, but a short time later, they were told he was dangerously ill and they rushed back to find doctors trying to save him. We were taken in, and we were told to talk to him and hold his hand. And then. We had a conversation with the consultant, and he said, you know what, were going to stop. Its not helping. We want him to die in your arms. 0n the unit, there were typically up to three deaths a year, but in 2015, they had that number in the month ofjune alone. And the pattern continued, with babies dying or coming close to death. The common factor lucy letby. This Staffing Sheet shows she was the only employee who was present every time there was a suspicious event. Dr Stephen Brearey led the team of seven consultants on the unit who shared joint concerns about letby. Hes now speaking publicly about their experience for the first time. Its something that nobody really wants to consider, you know, that a member of staff might be harming the babies under your care. Things came to a head when two out of three healthy triplets died within 2a hours of each other injune 2016. Afterwards, a meeting was held for staff. Lucy letby was there. She was sitting next to me. I spoke to her and said how tired and upset she must be after two days of this, and i hoped that she was going to have a restful weekend. And she turned to me and said, no, im back on shift tomorrow. The other staff were very traumatised by all of this. We were crumbling before your eyes, almost, and she was quite happy and confident to come into work. Lucy letby was eventually moved to a clerical role. The doctors kept trying to get managers to investigate the suspicious deaths and her connection to them. But we can now reveal that even though consultants here repeatedly made loud warnings to senior management, they say they were ignored and ultimately told that if they didnt stop raising questions about the nurse, thered be consequences. And the doctors say that even after lucy letby came off duty on the Neonatal Unit, executives tried to draw a line under the case, and it was only a year after she stopped working as a nurse that the Police Became involved. After her arrest, officers found all sorts of items in her bedroom babies� medical records, her diary and notes covered in letby� s scrawl, with phrases including, i am evil. I did this. She is a killer, and using her words, she is evil. Youve spent time interviewing her and watching her in court, as well, giving evidence. Yes. What do you make of her . I think shes very emotionless. She doesnt respond to a typical Human Response that i wouldve expected. Did you have concerns that there was a rise in the Mortality Rate . Yes. There was no empathy or sympathy with whats gone on at all. I mean, there are people who look at her and say theres no way she can have done this. Its circumstantial evidence. She looks as though butter wouldnt melt. Its an example to us all of not judging a book by its cover. I weve got to accept, you know, and understand the evidence i in this case has been, i believe, significant,| and it has taken us to understand that lucy letby is a killer. As the trial ended today, letby refused to come into the courtroom. Prosecutors later reflecting on the scale of her deceit. In her hands, innocuous substances like air, milk or medication like insulin would become lethal. She perverted her learning and weaponised her craft to inflict harm, grief and death. The nurse even wrote this Sympathy Card to the parents of one baby and searched for many of the other families on facebook, checking up on them voyeuristically months and even years after attacking their children. I want her to be locked up. I dont ever want her to come out again. Because what shes done has changed the course of our life forever. Lucy letby had many faces party girl, graduate, bright young nurse, but each face was a mask for evil hiding in plain sight, and at last her cover has slipped. Lucy letby will now be known as one of britains most notorious criminals. Judith moritz, bbc news, manchester. Lucy letby has today been convicted of seven murders, but the bbc has learned there were actually 13 deaths on the Neonatal Unit where she worked in a one year period. Thats five times the usual rate and the nurse was on duty for all of them. Asjudith was reporting there, doctors on the unit were raising concerns for months about letby, but senior managers ignored their warnings and protected her. 0ur social Affairs CorrespondentMichael Buchanan has this exclusive report. This is the story of an nhs trust that didnt properly investigate why 13 babies died unexpectedly in a one year period. Instead, it turned against the very people who wanted the police to examine the deaths. There is only one Serial Killer of babies thats worked in that organisation, and the Executive Team were not the people who were responsible for the deaths of those babies. But they had some opportunities to get to the bottom of what was happening. Susan gilbyjoined The Countess Of Chester Nhs Trust as Medical Director a month after lucy letby was arrested. Within two months, she was made chief executive, a post she held until last december. Through documents and speaking to staff, she learned what the trust knew about the Serial Killer. The first three babies died injune 2015. The Executive Team held a meeting at which it was agreed that an external investigation into the deaths would be held. It never happened. By october, with seven babies now dead, a Staff Analysis of the incidents made a link between all the deaths and lucy letby being on shift, but it was still seen as coincidental. In february 2016, with ten babies now dead, the director of nursing, alison kelly, and ian harvey, the Medical Director, were asked for an urgent meeting to discuss the deaths and lucy letby� s links to all of them. They didnt respond for three months. The paediatricians were discussing, you know, the terrible nights on call that they were having. One of them said, every time im. You know, this is happening to me, that im being called in for these catastrophic events which were unexpected and unexplained, lucy letby is there, and then Somebody Else said, yes, ifound that. And then someone else had the same response. And they all realised that the common factor for each of them was letby� s presence on the unit. Injune 2016, two babies died on consecutive days. 13 children had now died. Lucy letby was on shift for all of them. The day after the second death, the nurse was due back on the unit. Paediatrician Steve Brearey rang the duty manager asking for letby to be replaced. The manager refused. I challenged her. I said, well, are you saying that youre making this decision against the wishes of seven Consultant Paediatricians . And she said, yes. And i said, well, if youre making this decision, are you taking responsibility for anything that might happen tomorrow to any other of our babies . And she said, yes. Letby went to work, and a baby unexpectedly collapsed. We were urging them to investigate our concerns appropriately, and most of us felt the most appropriate way to do that would be to go to the police. The response from the Medical Director was unsupportive. In an e mail to the paediatricians obtained by panorama, ian harvey wrote, action is being taken. All e mails cease forthwith. The police were not called. Instead, in september 2016, the Royal College of paediatrics and child health was asked to carry out a review of the Neonatal Unit. It urged the trust to investigate each death individually. This didnt happen. Around this time, lucy letby launched a Grievance Procedure against the paediatricians. The internal process concluded that shed been discriminated against and victimised by the doctors on the unit. With the paediatricians wanting a police investigation, injanuary 2017, an extraordinary Board Meeting was held. The Medical Director, ian harvey, gave a verbal report. He said external reviews had not highlighted any individual as being linked to the deaths and that the trust was ready to draw a line under the issues. The chief executive, tony chambers, said hed met lucy letby and her parents to apologise for what had happened. A statement Written By Letby was read out detailing how hard the past few months had been for her. The meeting decided lucy letby would return to the Neonatal Unit after the paediatricians had written a Letter Apologising to her. This is the letter they sent lucy letby, signed by all seven paediatric consultants in the unit. Against their wishes, they apologised for any inappropriate comments that may have been made, going on to say, we are very sorry for the stress and upset that you have experienced in the last year. Though the paediatricians feared being reported to the regulator, they kept going, pressurising executives to call the police, something the trust eventually did in may 2017. The reputation of the organisation and protecting that reputation was a big factor in how people responded to the concerns raised. They were dragged kicking and screaming, the Executive Team, to call in the police. That would certainly be the conclusion that i would reach. At the time letby was arrested in july 2018, she was still working at the trust. No disciplinary action had been taken against her. The strong opinion was that there would be nothing found. There was a Brief Overlap of three or four days between myself and the outgoing Medical Director, and his parting words to me, to my surprise, were, you need to refer the paediatricians to the gmc. The former Medical Director denies threatening to report the doctors to the General Medical Council for misconduct. In a statement, tony chambers, the former chief executive, said. The former Medical Director, ian harvey, said. Both men say theyd co operate with the upcoming inquiry. Michael buchanan, bbc news, cheshire. The families affected have sat in this court room behind me month after month, and the parents of Twin Brothers who were among lucy letby� s 13 victims say she should spend the rest of her life behind bars. Baby e, the fourth of seven babies murdered by the nurse was killed by an injection of air into his bloodstream. Within 2a hours, letby tried to kill his brother, baby f, with insulin. Medics were able to save him but his parents say hes been left with complex needs. Judith moritz has spoken to them. In the corridor, i could immediately hear crying. It was. It felt more than crying. It was screaming. It was screaming, and i was like, what. What� s the matter with them . I walked into the room. I seen her with my boy, and he had blood round his mouth, and lucy was there, but faffing about. You know when it feels like somebody wants to look busy but theyre not actually doing anything . What did lucy letby say to you . Lucy said, now, dont worry. She has this really calm demeanour about her. And shes, you know, very, very softly spoken. And dont worry, the registrar was coming, shed already contacted him, he was on his way, and she told me to go back to the ward. I was trying to reassure my wife that, listen, these people are experts and, you know, if they say theres not a problem, youve got nothing to worry about. That was the first phone call. Quickly followed up by a second phone call with a midwife, saying, you need to get here now. And there was a third phone call telling me, where are you . The priest has been called. And ijust knew. I knew at that point. You know, you dont call a priest unless someones dying. What could you see . We were taken in. And we were told to talk to him and hold his hand. He was christened. The consultant said, you know what . Were going to stop. We want him to die in your arms. Rather than being worked on. So we said, ok. And they passed him to us. And he died. Can you just talk me through what happened in the aftermath of losing your first child . How was your other son doing . One of the nurses said, you know, hes not. He� s not well. His heart rate is really, really high. What was your first thought . Its happening again. I thought it was happening again. And i said to my husband, please, not again. We cant do this again. This cant be happening. Its almost bang on 2a hours since our other son had died. So i went and. I sat with him all night. His heart rate was absolutely through the roof. You know, it didnt come down, and i wasjust, like, just come down, you know. And im almost trying to will the machine, you know. Bring his heart rate down, bring his heart rate down. Make it ok. And did he recover easily . Hes got severe learning difficulties. Hes got a lot of complex needs. Is it your belief that thats connected. Yes. To what happened . Yes. Directly as a consequence . Theres a consequence, and hes living with it. What do you think when you go into court and you look at lucy letby . I think shes a hateful human being. Shes taken everything from us. Absolutely everything. Itsjust beyond your imagination that somebodys on a ward, killing babies. Its unbelievable. Because what shes done. Has changed the course of our life forever. You were one of the onlyjournalists to be sitting in the court room, watching it all, watching letby. What was it like . Yes, just a small number allowed into the courtroom itself. 0ur seats were three or four metres away from lucy letby� s seat, just through the glass wall of the dock. I spent months watching her. Harrowing, is the answer. Never mind me, imagine those parents. I was always aware thatjust next
