Mary Cressy Fuller Stone was a witness the night of the murder. According to her, she was babysitting for her daughter at 412 A for the evening. When she was on her way to her's daughter's house to babysit, she saw a stranger standing at the corner, apparently waiting for a streetcar. He didn't board the streetcar and she became frightened. Mrs. Stone waited at the lighted corner before she crossed the street & watched as the man turned on Alvarado & into Maryland, walking toward her daughter's place. When she was putting her granddaughter (Lynette Thompson, age 9) to bed, she heard what sounded like a pistol shot. After she put the little one to bed, she looked down into the courtyard & saw a weird pattern of light and shadows. Apparently, she wasn't interviewed by the police.
