Jeremiah Warthen, 27, was apologetic when officers escorted him into a DeKalb County courtroom for his first appearance Thursday.
"I just want to say I'm sorry man. It was an accident," said Warthen.
Police accused Warthen of fleeing from officers and causing a crash that killed a young child and an adult Wednesday night.
The fatal crash happened in the 4300 block of Snapfinger Woods Drive in DeKalb County.
Inside the red sedan were three children and three adults. A woman, 57-year-old Alicia Moxley, and her granddaughter, 3-year-old Jordan Haynes, were killed in the wreck.
Zakyia Davis said it happened after her parents and sister picked up her niece and two nephews from day care.
"They get out at 6:30 p.m., literally 30 minutes after picking up the kids it was over. My sister, my father, my two nephews they are in critical condition and my mother and my niece they are not even here," said Davis.
Police said Warthen got violent when an officer pulled him over during a traffic stop.
"He did ram our police car and fled the scene," said Assistant Chief Dale Holmes. "We lost sight of the vehicle, and as we searched for him, non-chase - I want to re-iterate, there was no chase here - we lost sight of him. We rolled up on the car, there was an accident with a small red sedan vehicle with six occupants."
The other four passengers, including two boys, ages 5 and 7, a 17-year-old girl who was driving the sedan and a 58-year-old man, were taken to area hospitals with serious injuries.
"We do have witnesses that stated it was a high rate of speed, that observed the accident," Holmes said.
Police said Warthen was charged with a laundry list of charges, including felony hit-and-run, aggravated assault on an officer, obstruction, reckless driving, aggressive driving, driving on the wrong side of the road, repeat traffic violator, failure to wear a seatbelt, and trafficking cocaine.
DeKalb County police spokeswoman Mekka Parish also told CBS Atlanta News that investigators found two ounces of crack cocaine in the hotel room in which Warthen was staying.
Davis said she regrets not telling her mother she was proud of her. Her family is grieving but thankful they didn't lose more family members.
"I would love to have them back, but we are blessed that God didn't take all six of them because I don't know what I would do," said Davis.
