A British teenager thought to have killed herself after she or her boyfriend allegedly shot dead a Florida police officer left a note revealing the depths of her despair, police have revealed.

Alex Hollinghurst, 17, originally from Manchester, was found dead with boyfriend Brandon Goode, 18, near where Officer Robert German was fatally shot.

He had called for back-up as he investigated the presence of a suspicious man and woman in a gated community in an affluent suburb of Orlando.

She left letters for her mother, father and 12-year-old sister.

The letter to her mother showed the depths of her despair.

“I could write to you for days, but I know nothing would actually make a difference to you,” she said.

The letter to her father said she was sorry to disappoint him. “I wish we could rewind. I love you to death but I just couldn't do it anymore. Everyday became harder and harder,” she told him.

And she told her sister: “I need you to know that you've always been my favourite, my number one. You're so much younger, but you're a better person than me, you always have been.”

Mr Goode's note to his parents said: “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!).

”I miss you so much already. I love you mom. I love you dad.“

In other notes released by Polk County Sheriff's Office, Mr Goode wrote to Miss Hollinghurst talking about a plan to elope to Panama. ”We could live on the beach, just me and you forever in our small little cozy house,“ he said.

The notes did not make any reference to the shooting of the police officer.

A spokeswoman for the Orange County Sheriff's Office has said the teenagers are possible suspects but have not been ”conclusively linked“ to the murder.

Orange County Sheriff's Office has said that the couple ”died of what is believed to be gunshot wounds from apparent suicide“.
