A former tenant of the founder of an African American history museum in Louisiana was charged Tuesday with her murder, authorities said.

Ronn Bell was arrested for allegedly killing Sadie Roberts-Joseph, who was found dead in the trunk of her car on Friday, Baton Rouge police announced. He was charged with first degree murder.

 

A preliminary autopsy conducted by the East Baton Rouge Parish Coroner's Office showed Roberts-Joseph, 75, died of traumatic asphyxia.

 

Police said they did not have a motive yet in the case but that Bell was a tenant in one of Roberts-Joseph's rental houses and was several months behind on his rent.
