Officers responded to reports of a fire near 29th and Villard streets just before 10am on Sunday 26 February and found Henderson inside.
Police are investigating her death as a homicide and continue to search for suspects.
“Black Trans Women continue to be at the highest risk for homicides within the LGBTQ community,” said a Facebook post from LGBTQ+ organisation Diverse & Resilient. “The continued attacks by right-wing elected officials to remove safety and rights for Trans people are causing an increase in vitriol and hatred toward people of Trans experience. We call for an immediate halt to the hateful rhetoric and the dangerous bills that are written as a result of transphobia and lies.”

Veronica Beck, Henderson’s cousin, has set up a GoFundMe page to raise $4,000 (£3,316) for funeral expenses to give her beloved relative the send off she deserves.
“She was a bubbly spirit with a down to earth, tell it like it is personality,” the page says. “Cashay was a transgender female and was as beautiful as can be, inside and out. Cashay didn’t deserve what happened to her.”
