Police believe that there is a serial killer on the loose in Dallas, that's hunting down Black transgenders - and murdering them.

Muhlaysia Booker, 23, was fatally shot early Saturday. She was killed weeks after being assaulted by an angry mob in a video that went viral.

Police arrested one of the men who allegedly attacked Muhlaysia -  Edward Thomas, 29, and charged him with assault and a possible hate crime. But police say he is not linked to Muhlaysia's shooting death.

Police currently have no leads on Muhlaysia's killer.

In October 2018, a transgender was found shot to death in a vehicle parked in southeast Dallas, according to NBC News. That murder is also considered unsolved.

In April, a transgender survived after being repeatedly stabbed in south Dallas. Police have no suspects in those cases.

These cases, although not directly related at this time, do have some similarities the public needs to be aware of," Maj. Vincent Weddington told reporters at a news conference Tuesday.

Two of the 3 victims got into a car near an intersection in the area of Spring Avenue and Lagow Street - just before the attacks, Weddington said.
