“Vanessa to me, she was and she continues to be my little sister, my best friend, everything, we grew up together," said Mayra Guillen, her sister.

“I applaud Mayra’s commitment, not just to Vanessa, her legacy and her family but to our country because she changed something that was historically impossible," said Natalie Khawam, the Guillen Family's attorney.
“It’s hard to believe, honestly, I never saw myself doing this but it only shows what the love of a sister can do," said Mayra.
