At this time, police have no leads or suspects in the case.
Muhlaysia Booker was found shot to death over the weekend say Dallas police. She is transgender.
Last month Booker, 23, made headlines after a mob gathered around her and watched as she was kicked, punched and verbally abused. The whole thing was captured on video.
Her body was found on Saturday lying face-down in the street, police said in a Sunday press conference. She was pronounced dead at the scene.
Investigators have no suspects or leads in the case and have yet to announce whether it is a hate crime or not.
Dallas Mayor Mike Rawlings (D) posted on Twitter that he hopes people will come forward and help the police find the killer.
"I am deeply saddened to learn of the murder of Muhlaysia Booker. I call on anyone with information on this homicide to please contact the Dallas Police Department," he wrote.
Booker was involved in a minor car accident back on April 12. A bunch of people gathered around her after the crash and watched as she was beaten until she blacked out.
Police arrested one of her assailants, Edward Thomas and charged him with aggravated assault.
The victim suffered major injuries including a facial fracture. Afterward, she told authorities she heard people yelling trans and homophobic slurs. Subsequently, police treated that incident as a hate crime.
Trans women of color face high rates of injury and even death as a result of hate crimes.
The Human Rights Campaign Foundation has deemed the epidemic a national crisis.
