On Tuesday, the Gwinnett County Medical Examiner's Office identified all five as those who lost their lives Sunday morning when a fire ripped through a home on Post Oak Drive in Duluth. They died from smoke and soot inhalation, officials said.

It was unclear if all five lived at the home, which was being rented.

As of Tuesday, fire officials were still investigating the blaze and had not determined an official cause. They have, however, suggested that the flames may have originated in a fire pit on the back deck.

The fire broke out around 3:30 a.m. Sunday, waking neighbor Tony Segars.

“It looked like a bonfire had gotten out of control,” Segars told The Atlanta Journal-Constitution on Monday. “As I came downstairs, it was fully engulfed.

“It’s a tragedy for the whole family,” Segars said. “I don’t know what else to say.”

According to friends, social media posts and online fundraising pages, Danielle Waring was just three days shy of her 20th birthday. A graduate of Loganville's Walnut Grove High School, she had a 2-year-old son who lived with his great-grandparents.

David Waring Sr., Danielle’s father, was a graduate of Stone Mountain’s Redan High School, according to his Facebook page.

“They are a wonderful family,” friend Blair Woods told The AJC on Tuesday, “and the remaining family is staying strong as much as they can be.”

Cameron Brown’s Facebook page suggests that he, like his girlfriend, graduated from Walnut Grove High.

“God, he was so funny and he always made sure to tell me he loved me everyday!” a friend posted Tuesday.

Tomkinson and Lewis’ connection to the others was unclear Tuesday.

Tomkinson “was an amazing woman and had one of the truest most kind souls I’ve ever known,” a friend wrote on Facebook.

Lewis' Facebook page listed her as a Redan High graduate. According to a fundraising page on GoFundMe.comshe had two young daughters.
