Olivia’s mother, Charlotte Cambell, told CNN that she had last spoken to her daughter at around 8.30pm before the performance.
Ariana Grande was one of Olivia’s favorite artists. Her mother had even bought the teenager new clothes to wear at the concert.
“It’s the most horriblest feeling ever,” Ms Campbell recounted. “To know your daughter’s there and you can’t find her, you don’t know if she’s dead or alive ... And I don’t know how people can do this to innocent children.”
The mother posted an emotional tribute to the teenager on Facebook today confirming the sad news.
“RIP my darling precious gorgeous girl Olivia Campbell taken far far to soon go sing with the angels and keep smiling mummy loves you so much,” she wrote.
