DALLAS (CBSDFW.COM) – A second death in the transgender community in Dallas is setting off alarm bells after another transgender woman was murdered in Dallas last week.

A transgender woman was pulled from White Rock Creek on Saturday, just before 7:30 p.m. Dallas police say she was severely decomposed.

She didn’t have an ID or identifying marks, so police called a news conference Tuesday afternoon to ask for the public’s help in identifying her.

Her cause of death is not yet known but this is the second transgender woman to die in Dallas in the last week.

“I can’t speak for everyone, but it makes us feel like our lives are disposable, at the rate that we are murdered,” said Leslie McMurry of the Dallas Resource Center of Dallas.

Police say 26-year-old Carla Pavon was strangled in an apartment.

Witnesses told police a man was seen leaving her apartment before she was found unconscious. She later died at the hospital. Police they have no evidence to suggest Pavon’s death is a hate crime.

Statistics for life expectancy for transgender women are staggering. The average white woman in America can expect to live 81 years, according to the Center for Diseases Control.  Black women will live just shy of 79 years. The CDC doesn’t measure life expectancy of transgender women, but several LGBTQ groups estimate it’s between 31 and 35 years.

“If that doesn’t tell you everything you need to know about how difficult life is, as a transgender woman of color, I don’t know what does,” said McMurry.

Police say the two cases aren’t related right now.

Anyone with information on the death of the woman found in the creek is asked to contact the Dallas Police Department.

Police said the latest victim is a black, transgender female about 5’3” approximately 130 pounds.

Police said a kayaker called to report a body in White Rock Creek near 6900 Merriman Parkway.

Dallas Fire-Rescue pulled the body ashore and the Dallas County Medical Examiner took custody of the body.

Police are calling this an “unexplained” death at the moment.
