Dollie Evans, 67, was fatally shot in the back of the head at her home on the 4700 block of Vista Street in the Tacony neighborhood of Philadelphia on August 23, 2014. Known in her neighborhood as Grandma and remembered for her kindness, she and a friend, 57-year-old Ruby Thomas, were attacked during what investigators described as a robbery. Both women were killed.

Police identified James Mears and Ronald Dorsey as suspects who targeted the women for money. Mears was arrested and charged with two counts of murder, robbery, conspiracy and related offenses three days after the killings; Dorsey was later sought by authorities in connection with the crime. The case drew notable attention because of the brutality of the attack and Evans’s standing in the community.

Does anyone have information about Dollie Evans, Ruby Thomas, or the events on Vista Street that could help resolve remaining questions?
