Text messages sent by Lucy Letby in the hours after she murdered babies on a neonatal unit were a key part of the evidence against her.
She was found guilty of murdering seven babies which were in her care, and attempting to murder another six.
The texts show how she offered to work extra shifts on the neonatal intensive therapy unit.
And, as her murders mounted, they also reveal how Letby reacted as the net of suspicion closed in on her.
The morning after murdering Baby D, Letby sends a message to a colleague:
Letby: We lost Baby D
Colleague: What!!!! But she was improving. What happened.
Letby:...on a day to day basis it's an incredible job with so many positives. But then sometimes I think, how do such sick babies get through & and others just die so suddenly and unexpectedly? Guess it's how it's meant to be.
Letby: I think there's an element of fate involved, I think it's just how it's memat to be.
Lucy Letby appeared in the dock several times since the start of the trial. She was not present today as the verdicts were delivered.
On two occasions earlier this month, she was in the courtroom and sobbed loudly or cried with her head bowed.
But she was last present in court on the morning of 16 August. It is believed she has at times been in the building during proceedings, but refused to come into the courtroom and instead stayed in the cells.
It is unclear whether Letby will be present on Monday morning for her sentencing. The Ministry of Justice has said that the Lord Chancellor has been clear that he wants "victims to see justice delivered and for all those found guilty to hear society’s condemnation at their sentencing hearing".
“Defendants can already be ordered by a judge to attend court, with those who fail facing up to two years in prison for contempt of court."
The senior investigating officer in the six-year probe that led to Lucy Letby today being found guilty of murder has released a statement about how the investigation unfolded.
"We had to go right back to the start, keeping an open mind and being careful not to draw any conclusions," said Det Supt Paul Hughes.
"The last thing we expected to find was a suspect responsible for these deaths and non-fatal collapses. It was a long, drawn-out process but no stone was left unturned. We had to do it right - not rush it.
"We had to deal with this as 17 separate investigations - we are normally used to dealing with one murder or attempted murder investigation at a time let alone something on this scale.
"What started out as a team of eight quickly increased and, at the height of the investigation, featured almost 70 officers and civilian staff working together.
"Turning up at the home of a family who have lost a baby, grieved for their loss and are trying to move on from that is difficult enough, but having to tell them that someone who was meant to be caring for their little one could ultimately be responsible for their death - is not an easy task."
