TEXAS CITY, Texas - At a home in Texas City, post it notes on a bedroom wall formed a tribute to an 18-year-old who committed suicide on Tuesday.

“My heart’s broken,” said Raul Vela. “I lost my angel today.”

Vela’s daughter Brandy was a Texas City High School Senior who he claims cried out for help from the bullies who were tormenting her on social media.

According to Vela, the harassment began more than a year ago when someone began using her picture online.

“And continually posting nasty things about her,” added Vela. “Set up an account saying she was actually soliciting sex.”

Then came the harassing calls.

“Sometimes she wouldn’t sleep. She’d call me at night. She’d say 'Dad, I can’t sleep. My phone keeps ringing.'”

The bogus pages would be taken down only to re-emerge days later. Brandy and her family complained to the authorities and to anyone who would listen.

“And nobody was willing to help. The help never came.” said Vela.

On Tuesday, Brandy sent out an email to her family members telling them she was going to kill herself. They rushed home and found her alive.

“And we tried to persuade her to put the gun down but she was determined. She said she’d come too far to turn back. It was very unfortunate that I had to see that. It’s hard when your daughter tells you to turn around. You feel helpless.”

Brandy committed suicide in front of her family moments later.

Texas City Police are investigating what happened as a cyber-bullying crime. So far, no one has been arrested.

We're told Brandy’s organs have been donated to those in need.
