“With this conviction, James Dixon has finally been brought to justice for this brutal and lethal assault,” District Attorney Vance said in a statement. “Members of the transgender community are far too often the targets of violent crime. I hope that this conviction provides some comfort to Ms. Nettles’ family and friends, and affirms my office’s commitment to protecting members of the LGBTQ community.”

Dixon is expected to be sentenced on April 19.
