A teenager who shot herself in front of her family after cyberbullies made fun of her weight is still being mocked by fake Facebook profiles.

Fake profiles showing Brandy Vela's face superimposed onto a pig and Photoshopped alongside guns have been shared with the Texas City Police Department.

"I thought this was all behind us but it's not over," her father Raul told KHOU. "I know what she was going through now. It's not that easy just to shut it off and let it go."

Brandy, 18, killed herself on Tuesday 29 November, placing a gun to her chest in her bedroom in front of her parents and grandparents.

Speaking in the days after her death, the family told local news source Click2Houston that anonymous messages sent through encrypted apps and fake Facebook profiles mocked their daughter's weight.

Her sister Jacqueline, 22, said: "They would put her picture and lie about her age and say she is giving herself up for sex for free.... [The authorities] always say the same thing: they can't do anything about it."

Facebook apologises to LGBTQ community over naming policy

The attacks were reported to the police, but the messages could not be traced. The recently-created Facebook profiles have since been removed by the social media company, following complaints registered by friends, family and supporters.

Following Brandy's suicide, the Texas City Police Department said in a statement that it was investigating the cyber-bullying attacks. No arrests have yet been made.
