A candlelight vigil will be held tomorrow evening for transgender woman who was killed yesterday afternoon. Joshua Mack, known to friends as “Na Na Boo,” died at Howard University Hospital at 3 p.m. yesterday. Another transgender woman, who has not been identified, was also stabbed, and survived.

The vigil will be held at the site of the incident, 209 Q Street NW at 6:30 p.m. The event is being organized by Transgender Health Empowerment, which counted Mack as a client, in order to “condemn this recent violence and urge the community to come forward with any leads.”

Meanwhile, police are investigating the possibility of a hate-bias motivation to the crime, the Washington Post reports:

Two transgender people who were stabbed Wednesday, one fatally, in Northwest Washington might have been victims of a hate crime, D.C. police said, although investigators have not yet determined what led to the violence.

. . . The incident is being investigated as a potential hate crime based on “a shred of information” that detectives obtained from the survivor, according to acting Lt. Brett Parsons, the department’s top liaison to the city’s gay community.

The surviving victim told a detective that the attacker might have used an anti-gay epithet during the incident, Parsons said. But it would be “extremely premature” for authorities to definitively classify the crime as having been motivated by the victims’ gender identity, he added.

“Until we’re able to do a really detailed interview with the surviving victim, I’m not sure that anyone really knows,” Parsons said.
