Ramona Shelton's sister, Amanda Anderson, said Wednesday that she cannot imagine why anyone would want to hurt her sister.
"It is a mystery, so we really need the help of the community at this time. She's poured out so much, and so we need some of that reciprocated," Anderson said
Shelton, a mother of six who was active in her church and community, was found dead Thursday afternoon with multiple gunshot wounds insider her car which was parked in the 15500-block of South Paxton Avenue.
Shelton was last seen at 11:35 a.m. when she left to get lunch for contractors working on her home, according to the Cook County Sheriff's Office.
Police said it appears she never left her driveway.
