New Orleans Police believe they have the man in custody responsible for the murder of 75 year old Sadie Roberts-Joseph, the founder of the African American Museum in Baton Rouge, New Orleans. After her body was discovered in the trunk of her car last Friday, an autopsy revealed she died of "traumatic asphyxia". "It is with great sadness and respect we investigate any unexpected or traumatic death," the coroner's office said Monday. "When our investigation involves an innocent victim, such as Ms. Sadie Joseph, it is particularly tragic. Our condolences are extended to Ms. Joseph’s family and friends." A sex offender Ron Jermaine Bell, who owed Roberts-Joseph $1200 in unpaid rent, has been arrested and charged with her murder.
