On May 23 last year, 47-year-old mum of three Deborah Byrne was scrolling through her Facebook feed.
Deborah – from Northhampton – began to notice that there were memorial tributes posted to her 21-year-old daughter Brogan Warren.
One message said “gone too soon”, while another read, “I can’t believe the news”.
When a friend private messaged Deborah to share their condolences, the mother said “the penny dropped”.
"A friend of Brogan's wrote to me 'I'm so sorry' in a private message, so I asked what the hell she was talking about," Deborah told The Sun.
"She said there had been a horrific crash the night before, on May 22, and she would be there for me. That’s when I started screaming...Brogan was dead.
“At that moment my heart shattered.”
After gathering her family and sharing the news, Deborah said she frantically tried to contact police for more information.
"We were desperately trying to get hold of the Northamptonshire Police to get official confirmation of what had happened," she said.
"But because the crash had happened in Oxfordshire, 45 miles away, Brogan's name wasn't coming up on our local police's system.
I couldn't believe I'd found out about my daughter's death on Facebook."
