NeVaa White, a friend, told Mic that Ms. Tyrae had been out since at least 2009, and had a close community of friends. “She made family with her peers in the L.G.B.T. community of Baton Rouge,” Ms. White said, adding that Ms. Tyrae didn’t have an easy life, and that she “was taken away in the very manner she feared.”

Statistics on homicides of transgender people are difficult to compile and are not officially available because the federal government does not collect data based on gender identity. In addition, transgender homicide victims are often identified by the police using the names and genders they were assigned at birth, a practice known as misgendering.

Advocates emphasize that their tallies just include the victims they know about.

“It is impossible to have a complete and accurate number,” MJ Okma, an associate director at Glaad, said.

Transgender people frequently face economic hardships, discrimination in housing and hiring, and high rates of homelessness, Mr. Okma said, all factors that can contribute to systematic violence. “That becomes the greater context,” he said.

In 2016 in Louisiana, Gov. John Bel Edwards, a Democrat, issued an executive order that protected L.G.B.T. employees and contractors from discrimination, the first time that the state had explicitly recognized the equal rights of transgender people, according to the American Civil Liberties Union.

But transgender people have continued to be targeted in the state. Three transgender women were murdered there in an eight-day period in February 2017.

“Violence against trans people, mostly trans women of color and often resulting in death, continues to plague our communities,” the group Louisiana Trans Advocates said at the time.

“We must also recognize that the shameful content and tone of the national discourse on trans issues contribute to stigmatization and dehumanization that lower the barriers to this kind of violence,” the organization said.
