BATON ROUGE, La. (AP) — Police in Louisiana say Baton Rouge’s African American history museum was reported to have been vandalized exactly a month after its founder was found dead.

News outlets report police are investigating the damage to the Odell S. Williams African-American Museum founded by Sadie Roberts-Joseph.

Photos posted online Monday show flipped benches, windows on the ground and other damage including torn and ruined landscaping. It’s unclear if the inside of the museum suffered any damage. It’s been closed since Roberts-Joseph’s death.

The 75-year-old Roberts-Joseph was found dead last month in the trunk of a car. Preliminary autopsy results showed she was strangled before being shoved into the trunk. Police later arrested 38-year-old Ronn Bell on a charge of first-degree murder. He had been renting from Roberts-Joseph and was about $1,200 behind in rent.
