A man who did not want to be identified says he found the body.
"And I went over there and I started putting the fire out," said the man.
"Then when I started hitting the ground I said, 'Oh wait! This is a body!' And then I was like, 'Oh my goodness!' After I did that, I just kept on doing it, I just kept on trying to put it out. It was too late."
The coroner's office says the woman appears to be caucasian.
Detectives say the body was inside a 50-gallon commercial trash can and had been doused with an accelerant.
