BATON ROUGE, La. -- A Louisiana coroner has ruled the death of a 75-year-old woman who founded Baton Rouge's African-American history museum a homicide by suffocation.
East Baton Rouge Coroner Beau Clark released preliminary autopsy results Monday that show Sadie Roberts-Joseph was suffocated before her body was found in the trunk of a car Friday.
He said Roberts-Joseph died from "traumatic asphyxia, including suffocation."
The Advocate reported this means her airways were physically blocked, cutting off her oxygen supply.
The paper reported that Roberts-Joseph founded the Baton Rouge African American Museum in 2001.
Shortly after announcing the discovery of Roberts-Joseph's body, the Baton Rouge Police Department posted that "Ms. Sadie was a tireless advocate of peace," and added investigators were working to identify a suspect.
