Giving evidence, he recalled commenting at the meeting, “it can’t be Lucy, it’s not good Lucy.”

Dr. Brearey also said that Eirian Powell, the nurse manager for the neonatal unit, first noticed a connection while conducting a review of three events in June 2015.

According to Dr. Jayaram, although the review carried out identified the presence of Letby in several cave-ins, it was “an association, nothing more”.

But by the fall, the atmosphere had changed, and some doctors had “significant concerns,” Dr. Jayaram told the court.

“They were on the radar of someone as high up as the chief nursing officer since October 2015.”

Dr Jayaram told ITV News he believed lives could have been saved if hospital chiefs had contacted the police earlier, adding: “I really think there are four or five babies who could be going to school now. and that they are not.”

Although he expressed concern, it appears that no action was taken.

“As physicians, we rely on the system, on senior management to escalate concerns and investigate them. The initial response was, ‘it’s unlikely that anything is going on. We’ll see what happens,’” the doctor said in his statement.

In an interview, Dr Brearey told the BBC that he raised concerns about Letby in October 2015. The doctor said he contacted Ms Powell, who did not appear to share his concerns.

In an October 2015 email reported by the station, he described the association between Letby and unexpected infant deaths as “unfortunate.”

“Each cause of death was different,” he said, adding that the association with Letby was just a coincidence.

Dr Brearey also told the BBC that his concerns were passed on to the director of nursing, Ms Kelly, but she claimed she received nothing.

It is unclear whether these conversations took place before or after the October 23 death of Baby I, whom Letby has now been convicted of murdering.

Sometime in the second half of 2015, Dr. Jayaram recalled in court that some of the doctors “had already begun to express concerns about the association that we had seen with a person present in these situations,” but “at that At that time they were telling us that we really shouldn’t be saying those things and not to make a fuss.”

Dr Jayaram said he and another consultant raised their concerns about Letby again in February 2016.

The doctor said his colleague, Dr Brearey, requested a meeting with the medical director, Ian Harvey, and the nursing director, Ms Kelly, but said they were slow to respond.

“My colleague, Dr. Brearey, requested a meeting with them. They didn’t respond to that for another three months and we got stuck because we had concerns and didn’t know what to do,” he said in court.
