LABELLE, Fla- A LaBelle woman was found dead in an abandoned house early Sunday morning on Seminole Avenue, according to the Hendry County Sheriff's Office. 

Investigators say the house Pearl Smith, 44, was found in had been vacant for a very long time.

"They are treating it as homicide although they don't know if it's a homicide yet," said Lt. Susan Harrelle of the Hendry County Sheriff's Office.

Smith's family believes she was killed. 

"She was bipolar and schizophrenic, but everybody knew she wouldn't harm anybody," said Don Johnson, Smith's brother.

They want the person responsible for her death behind bars. 

"We love her dearly, and we hope justice reveals itself," said Smith's brother.

Investigators ordered an autopsy, and hope it will provide them with answers in this case.
