A woman who died as result of “homicidal violence” in Dallas became the third transgender woman killed in the city within 8 months — sparking an FBI probe, cops said Monday.

The body of Chynal Lindsey, 26, was pulled from a lake by Dallas Police on Saturday less than a month after another black transgender woman, 22-year-old Muhlaysia Booker, was found shot to death in the city, according to ABC News.

Dallas police Chief Reneé Hall said Lindsey’s body had “obvious signs of homicidal violence” and asked both the public and the FBI for help in finding her killer.

“The Dallas Police Department has reached out to the FBI because as we know, this is the second individual who is transgender, who is deceased in our community,” Hall said at a press conference Monday.

“We are concerned, we are actively and aggressively investigating this case. And we have reached out to our federal partners to assist us in these efforts.”

An FBI spokeswoman said the bureau is “prepared to assist” if it becomes clear that there could be “a potential federal civil rights violation.”

“We will continue to work with the Dallas Police Department as well as all our community partners to address any concerns,” FBI officials said in a statement.

Dallas Police said the department has four open homicide cases in which black transgender women were killed — including Lindsey and Booker, according to the Dallas Morning News.

Booker’s death came one month after a video of her being attacked gained widespread attention online. She can be seen in the footage desperately attempting to fight back during the attack.

On May 18, Booker was found shot to death on a road bordering a golf course. Cops have not named a suspect in her killing.

Also, 29-year-old Brittany White was found fatally shot inside her car in southeast Dallas in October of 2018. Her killer is still at large.
