The death of a Black transgender woman whose body was found in a torched car in South Florida last week is being investigated as a homicide and possible hate crime, authorities said.

The body of Bee Love Slater, a 23-year-old trans woman, was found in a burned-out car on Sept. 4 in Clewiston. Her remains were so badly burned that it took investigators several days to identify her by dental records.

The Hendry County Sheriff’s Office is investigating the death as a homicide, telling NBC-2 it’s one of the most brutal killings the county has ever seen. Investigators said they had no suspects.

“We can’t say it’s a hate crime yet because we don’t know what the motive was,” sheriff’s Capt. Susan Harrelle told ABC-7.

Harrelle told the Miami Herald there was no evidence Slater was bound and shot before the car was set ablaze, as some reports said. The sheriff’s office said earlier that the body was “burned beyond recognition,” according to The Palm Beach Post.
