17-year-old Alex Hollinghurst allegedly ‘shot a policeman’ alongside boyfriend Brandon Goode before turning the gun on themselves.
Alex’s family reportedly believe that 18-year-old Brandon murdered their daughter before killing himself after gunning down 31-year-old police officer Robert German.
Alex had allegedly ran away from her family as they disapproved of her boyfriend Brandon’s drug use.
The teenager’s mother had reported Alex as missing just two days before the couple’s bodies were found near Kissimmee in Florida.
According to reports, straight A student Alex was an ‘habitual runaway’ and had been caught shoplifting prior to her disappearance.
According to a letter written to Alex’s mother, her relationship with her family was strained.
She wrote: ‘You are a waste of space, ignorant, and a rotten C***. I wish I were never born.’
Alex wrote that she thought her mother was ‘too ignorant and self-concerned to even attempt to listen or understand.’
‘Please understand that when people compare us I vomit on the inside,’ she shockingly added.
More disturbingly, she wrote: ‘If I had stayed another minute I would have painted the walls and stained the carpets with my blood, so you could clean it up.’
Alex apologised to her dad for ‘disappointing’ him in the letters to her distraught parents.
She also wrote: 'I'm sorry I've changed… I wish we could rewind. I love you to death, but I just couldn't do it anymore. Every day became harder and harder.'
In a heart-breaking letter to her younger sister, Alex wrote: ‘You're a better person than me, you always have been. I hope you never take a wrong turn like I did. I hope you continue to grow.’
Alex’s letters, however, did not directly state that she was planning on committing suicide.
Boyfriend Goode wrote in his own letter to his own parents:
'Don't be sad. This is what I want now. I get to die peacefully with the woman I love, the woman of my dreams, my fiancé (yes we're engaged!)' he wrote.
'I miss you so much already. I love you mom. I love you dad.'
Judging by letters from Alex to her boyfriend, she was planning on having a ‘mini-vacation’ with Goode.
She wrote to him: ‘I hope I get time. It'll be a mini vacation from my parents and when I come back I might be more grateful.’
‘I just need a break from the bitch,’ she added, before writing: ‘Living with you is going to be bliss.’
Alex’s family, who moved to the US from Britain 5 years ago, are still struggling to come to terms with their loss.
