Following the murder of his transgender sister, Mia Henderson, Detroit Pistons forward Reggie Bullock is using his platform as an NBA star to promote trans awareness and acceptance.

Henderson, 26, was found stabbed to death in Baltimore in July 2014. Bullock has said she was so badly beaten that police could not initially identify her body.

Bullock, who recently met with representatives from GLAAD and Athlete Ally, hosted a Pride Night at Detroit's Little Caesars Arena to affirm his support for the LGBT community and share his sister’s story.

"Just the impact that she had on my life and the happiness that she had with being herself always stuck with me even when she left," says the 27-year-old player in a new Pistons video spotlight.

“What happened to Reggie Bullock’s sister Mia Henderson was a tragedy and shouldn’t happen to anyone," adds Nick Adams, GLAAD’s director of transgender media and representation. "But the fact that Reggie Bullock wants to use this as an opportunity to talk about his support for LGBT people, and especially for transgender women, is really incredible.”

"It’s really about what you believe, what you stand for," continues Bullock, who has Henderson's name and "LGBTQ" tattooed on his leg. "I think if my sister wasn’t a part of that community and nothing like this totally ever happened, I still feel like I would probably be a leader to be able to stand up for that community."

Bullock has previously spoken out about his impatience for homophobic and transphobic jokes in the locker room.

Yesterday, in honor of International Transgender Day of Visibility, joined Athlete Ally on a panel focused on making collegiate athletics accessible and inclusive for trans, nonbinary, and intersex athletes. He recently called on NCAA schools to adopt trans-inclusive protections.

The man charged in 2015 with the first-degree murder of Henderson was later acquitted on all counts.

At least 27 transgender Americans were murdered in 2017, making it the deadliest year on record for the trans community.
