Sandifer's son, Kenneth Spivey, said his mom was an incredibly strong single mother of four.
One of the most caring women I know," he said "[She] taught me everything. [It] ain't too often you see a woman know how to teach men...boys how to be men, but she did that."
Spivey said even when times were tough his mother never asked for help and that she would always keep smiles on the faces of those around her.
"Always laughing, going to keep you laughing," Spivey said. "Even when you're down, she's gonna make sure you laugh."
Sergeant Clay Williams says this is Macon-Bibb's 27th homicide of 2018. Coroner Leon Jones says he’d like everyone to pray for this community.
