The shots were fired through the front door into the family's home on Polar Rock Place early Saturday.
"She was a good girl. Everyone loved Ty," said Antoine Shepard, Ty-Teyanna's father.
The children's uncle, Babe Woods, told FOX 5 that he thinks he knows who fired the shots. He says it stems from a dispute over some car rims.
"This is a 2-year-old girl who lost her life, no reason. No reason at all," said Woods.
The children's mother, Sylvia Motley, says that Isaiah, who has been hospitalized since the shooting, could be back at home at the end of this week.
In the days since, Sylvia Motley has returned back to her home. Although she's grieving the loss of one child, she's hopeful about the recovery of another.
"He's talking and moving around and trying to get down and walk," Sylvia said.
Atlanta police say they've received several tips in the shooting. They hope the reward for information in the case -- recently raised to $5,000 – will lead to more of those clues and a suspect.
"We're concerned with every homicide that we have, but certainly this rises to a significantly more violent situation just based on the recklessness of the individual who fired the shot," said Lt. Paul Guerrucci of the Atlanta Police Department.
"By everybody knowing about it, somebody is eventually going to say who did it, so he might as well come forward and turn himself in because he's making it hard for himself," said Sylvia Motley.
The vigil was especially hard on Ty-Teyanna's grandmother. She was the last one to see the 2-year-old alive. The grandmother fainted during the vigil and needed medical attention.
A memorial fund has been set up in Ty-Teyanna Motley's name. Donations can be made at any Wells Fargo Bank branch.
Anyone with information on the shooting is asked to call Crime Stoppers at 404-577-8477. Police are offering a $5,000 reward leading to the arrest and conviction of the person responsible for shooting the two children.
