: "What happened after she made that last TikTok video at 12:02am and she was dead at 12:23am? I need answers."
A 16-year-old boy has since been arrested in connection with the shooting, and has been charged with felony murder, aggravated assault, reckless conduct and possession of a pistol for person under the age of 18.
Kalecia was shot dead on December 26 But Ms Smith has said not enough is being done.
Along with other family members and friends, Ms Smith went to the hotel on Tuesday in a protest for justice.
"It was just a lot of foul play and I'm trying to put all the pieces together because I don't feel like the system is doing enough to help me," she said.
On December 26, Kalecia was supposed to go to a chaperoned party at an Airbnb, but it was later realised another parent had paid for them to stay at the Hyatt Regency.
"She was responsible for getting the hotel room for these minors," Ms Smith added.
"Her name was on the hotel room for these minors, so I feel like she should be held accountable for my daughter's death as well."
It is still unclear to police what happened to Kalecia in the moments after she recorded the TikTok video, but a woman who was staying at the hotel that night recently got in touch with the family.
Kanautica Starkie, from South Carolina, recalled to the news station what she had heard.
"They were shouting what hotel we at what hotel, she was panicking," she said.
"I seen two guys coming out the elevator with a little girl, holding her.
"One had one leg, one had the other and they were saying she had been shot."
Starkie said she held the 16-year-old's hand as they waited for paramedics to arrive.
She said she took a video of EMTs trying to resuscitate Kalecia, which has made the teenager's family more suspicious of what happened.
Kalecia's stepfather Ronney Savoy said: "The young girl said they moved my daughter's body because of the blood, but when we look at the video from the woman from South Carolina there was no blood, so we want to know the reason why you took her from the floor to the lobby."
Kalecia's family are urging any witnesses to come forward to Atlanta police department, even if anonymously.
