The family, community leaders and activists are calling for Emory to shut down its sleep center until a thorough investigation of Harris' death is conducted.
They delivered a letter to Emory's chief medical officer Monday calling for the center's closure and demanding that a copy of the video showing what happened to Harris in the time before his death be made available to both the family and the public.
State Sen. Vincent Fort expressed support for such efforts.
"They need to shut it [the center] down, have a thorough review of all the procedures and not open it until they can assure the public that it's being run the right way," he said.
In the statement, Emory said it "continues to express sympathy to the family of Mr. Harris" but it has no plans to release the video. "Emory cannot release the video recording of the sleep study because it must be viewed on special software that can only be seen in the sleep lab, where there are ongoing studies."
In the meantime, Fort said, he urged the public not to participate in any studies there.
"I would just tell the public if you're going to go over there, you need to think twice," he said. "If your physician or someone else assigns you or gets a referral over there, think twice before you go over there because what happened to Brandon could very well happen to them."
Michael Langford, a community activist with the United Youth-Adult Conference, has been heavily involved in the family's efforts. He said they have one goal in mind.
"Our goal is not to embarrass Emory but to make sure the public's safety is priority number one," Langford said.
The statement from Emory said the cause of Harris' death was sudden cardiac arrest. "Mr. Harris died because of 'sudden cardiac death,' meaning that his heart stopped suddenly and without warning," the statement said.
Officials from the Dekalb County Medical Examiner's Office said they conducted a medical examiners inquiry on the case and based on that inquiry, there was no need for further investigation.
"He had a medical history that could explain a sudden death," Paul Kelhofer, director of the Dekalb County Medical Examiner's Office, said.
Lewis said he hopes people remember his nephew, a medical assistant with hopes of one day working for Emory, for his warm, effervescent personality.
Family members have started a children's youth program in Atlanta in Brandon's name, he said.
"Brandon was a very humble young man," he said. "But at the same time, he was very outgoing, very caring. He just loved life."
