UPDATE: The family of a woman hit on Mississippi Avenue is grieving her loss.
Laura Sue Carden died Monday night after being hit by a car earlier this month. The driver took off and still has not been found. It happened December 12Th on Mississippi Avenue in Chattanooga, in the early morning hours. Police are still investigating, no arrests have been made. We sat down with Carden's family to talk about her death and how they are remembering her.

"Mom loved Christmas, she loved shopping and gift giving," said David Carden.

Laura Sue Carden's special tree is decorated, she hung the ornaments herself. 

"She was just a little woman but she had a big heart," said David Carden. 

This Christmas, Sue won't be here. For those she left behind it's still hard to believe that she's gone.

"You know it's hard," Said David Carden. "It's one of the hardest things you could do to say goodbye to somebody you love so much."

Her son David holds onto their precious memories together. He plans to keep his mom's tree a glow with faith that justice will come. 

  "Do what is right.... there is so many people hurting here," said David. 

The driver who hit his mother on Mississippi avenue on December 12th didn't stop, instead he took off. The 70-year-old grandmother was found in the road with a broken pelvis, broken collarbone, broken bones in her neck, a fractured leg, liver damage and a head injury. She died after weeks in ICU.

"We're hoping the person that did this may have talked with someone who could come speak to us or call in an anonymous tip or something that could lead to furthering this investigation," said Sgt. Justin Kilgore, Chattanooga Police Dept. 

Eyewitnesses  described the driver as a black male in a blue or silver Sedan. Police say the vehicle could be repaired by now. If not, it would have damage to the front. Police are also asking for leads.  

"Think about the family, think about what they are going through right now and come forward," said Sgt. Kilgore. "Just talk to us, let us know everything that happened that night."

It's a Christmas wish David hopes someone will grant, giving his family the answers they need. Family and friends are offering up a $2,500 reward for any information leading to an arrest in this case. Chattanooga Police ask anyone with information regarding this incident to call 423-698-2525. Funeral arrangements have not yet been made.

PREVIOUS STORY: A Chattanooga woman was seriously injured over the weekend when she was hit by a car and the driver kept going. Seventy-year-old Laura Sue Carden was hit as she was crossing Mississippi Avenue early Saturday morning.

Laura, who goes by Sue to family and friends, is known to walk in the early morning hours. Her family hopes the person who hit her does the right thing and comes forward.

"I was thinking she would die. And I just hated the fact that she'd gotten hurt. She's such a little frail thing," says Sue Carden's sister, Pat Lawson.

Lawson says all she can do is pray for her sister.

"I was just shocked to see how badly she's broken up. How horrible the accident must have been for her."

Around 3:30 Saturday morning Sue went for a walk.
"She'd get up at that time and walk and come back and get her coffee," says Lawson.
She was crossing near the 700 block of Mississippi Avenue in Chattanooga when a driver topped a hill and struck her and left the scene.

"They said there was no places on the road where there was any attempt to stop at all," says Lawson.

Sue is unconscious in the ICU. She has a broken pelvis, collar bone, fractured leg, broken bones in her neck, liver damage and head injuries.
"She's 70 years old. I don't know how she's going to do this," says Lawson.

"They lowered the speed limits through that area. They've got speed bumps through that area. It's a shame that this thing, something like this could still happen," says Stanley Carden, Sue's brother.

"My mother was very giving. She would give anything just to help," says David Carden, her son.

For the past 10 years, Sue has worked at the Sports Barn in downtown Chattanooga, keeping the place tidy and helping customers.

Friends of the family have started a Go-Fund-Me page to help with expenses.

"We've asked people to do prayer chains," says Lawson.

They are also asking for the driver who hit Sue to take responsibility. 
"Not that many people arrive at home at 3:30 or four in the morning so maybe we can narrow this down," says David.

There are witnesses to the accident. They describe the driver as a black male in a silver or blue colored sedan. Investigators say the car will likely have front end damage. If you have info that can help, call Chattanooga police at 423-698-2525.
