Charlotte Campbell spent Tuesday franticly searching for her 15-year-old daughter.
“This is my daughter Olivia, I haven’t seen her since five o’clock last night. She was at the Ariana Grande concert with her friend,” she said in an emotional plea to the public for information.
“Please just somebody get hold of her I’m worried sick, we’ve not slept,” she said.
“I’m going through hell, I can’t even explain what I’m going through. I need my daughter home, I need to know where she is. A mother shouldn’t have to do this.”
It was an agony experienced by many parents in the wake of Monday night's Manchester attack, a suicide bombing which killed 22 people, many of them children.
But by Wednesday, Campbell’s worst fears were confirmed. Her daughter Olivia was among the dead.

At a vigil in Bury, north of Manchester, Charlotte appeared before mourners to thank the community for their support.
“I can’t thank you enough for what you’ve done for us, for being here for giving us your support,” she said yesterday.
“This is such a hard time for us, I had to come, I didn’t know what to do, I don’t know where to be I don’t know what to do, I just knew, something told me I had to come her.”
She told the crowd that her family was united, and standing strong.
“I ask her friends, strangers relatives to do the same. Please stay together. Don’t let this beat any of us. Please don’t let my daughter be a victim.”
Police are continuing their investigations into the attack as the UK remains on high alert. Multiple arrests have been made as authorities scramble to identify those responsible.
Islamic State has claimed responsibility for the attack with the suspected bomber named as Manchester-born 22-year-old Salman Abedi.
