A 15-year-old Houston girl killed herself after she was rescued from a sex trafficking ring, according to a report.

Leticia “Letty” Serrano took her own life Saturday two years after her horrific ordeal, news station KTRK reported.

“I feel like I let her down,” her grandmother Cynthia Rivera told the news outlet.

Serrano was only 13 years old when she was drugged and sold to sex traffickers, KTRK reported. She was later found at Moody Park, but her family said she was never the same.

“We got her back damaged,” Rivera said.

Her family is speaking out to raise awareness about the prevalence of sex trafficking.

“We as a community and the system failed this young lady and her family once. Let’s not do it again,” her grandmother wrote on a Facebook page to spread the word.
