Background and Family
Vanessa Guillen, born in Houston, Texas, was one of six siblings in a close-knit family of Mexican heritage. Her sisters, Mayra (the eldest) and Lupe, grew up alongside Vanessa and have been deeply involved in preserving her legacy and seeking justice after her murder at Fort Hood in 2020
. The family has always been proud of their roots and maintained strong bonds, which shaped the sisters’ commitment to activism
Mayra Guillén has emerged as a prominent advocate for military personnel, particularly focusing on harassment and systemic issues within the armed forces. She is the founder and president of the Vanessa Guillen Foundation, which works to support service members and push for reforms
. In 2025, Mayra announced her candidacy for Texas’ 9th Congressional District, challenging incumbent Rep. Al Green, citing her desire to continue fighting for justice and represent her community politically
. Her activism has included working with politicians to advance the Vanessa Guillen Military Justice Improvement and Increasing Prevention Act, which reforms how serious crimes are prosecuted in the military
Lupe Guillén, Vanessa’s younger sister, was 16 at the time of Vanessa’s death and became a visible figure in protests and public advocacy. She has spoken about her personal struggles, including overcoming speech difficulties as a child, and has used her voice to honor Vanessa’s memory and raise awareness about military harassment and safety issues
. Lupe has been described as the emotional face of the family’s public efforts, often participating in demonstrations and media appearances to demand justice.
Together, Mayra and Lupe have been instrumental in keeping Vanessa’s story in the public eye, advocating for legislative changes, and supporting other military families affected by harassment or violence. Their combined efforts have made them central figures in the ongoing conversation about military reform and women’s safety in the armed forces
Both sisters continue to honor Vanessa’s memory through activism, public engagement, and, in Mayra’s case, political involvement, ensuring that her tragic death leads to meaningful change.
