MACON, Georgia (41NBC/WMGT) - Dr. Maggie Zingman started her journey over 66,000 miles and 46 states ago.
Her daughter Brittany was raped and murdered in her 2nd floor Tulsa apartment in 2004.
"She was a chemistry major," said Zingman. "She wanted to go into cancer research. She was going to school, working, and coming home, and she was murdered in the middle of the night, in her apartment."
To this day, Brittany's killer is still on the loose. Over 2,000 DNA samples have been taken, with no matches.
Zingman says if there were a law that required felony suspects to submit their DNA into a database upon arrest, her daughter might still be alive.
Twenty-six states have passed a law requiring those arrested for felony crimes to submit their DNA, but Georgia, and Oklahoma, where Brittany was murdered, are yet to jump on board. Opponents call such a law unconstitutional.
"The DNA that they use does not have any of what they call genetic secrets; it doesn't have diseases," said Zingman. "It doesn't have any of the family secrets. It's blank DNA, and if you look and do research on it, you'll find that they rule it's no different than fingerprints. All it does is identify if that individual is at the crime scene."
During the last session, Georgia lawmakers did pass a law that requires those convicted of felonies to submit their DNA, but Zingman says that's not enough.
"We've got to do it at all arrests because it doesn't hurt anybody, except the victims, if we don't."
