DALLAS (CBSDFW.COM) – DNA testing has released hundreds of wrongfully convicted prisoners. It could also exonerate another group – men who’ve been paying child support for children they do not believe are theirs.

Trey Andrews works as a Hyperbaric Oxygen Therapy technician. He’d breathe a lot easier himself if he didn’t have a $300 a month child support payment.

“For a child I don’t ever get to see and haven’t seen for about 10 years that I’m 95 percent sure is not even my child,” Andrews said.

Senate Bill 785 would end the relationship, releasing him from child support payments through DNA testing.

Dennis Fuller, an attorney in Dallas, said, “Texas is way down the list in addressing this injustice.”

Fuller says says DNA would exonerate men like Andrews the way it has exonerated prisoners.

But unlike exonerated prisoners, there is no restitution or compensation for an exonerated parent in the bill.

“I hestitate to even say this is justice. What I can say it is doing is preventing continuing injustice,” Fuller said.

Trey Andrews remarried and has a step son. This is the family he wants to take care of.

“It’s caused a lot of heartache between me and my wife because that’s money we could be using to pay bills,” Andrews said.

The bill would only provide Andrews with a window of opportunity. One he and many others are sure to take.

“I’m sure there’s plenty of other people out there in the same type of situation I’m in, if not worse,” Andrews said.

Both the House and the Senate passed this bill unanimously. If the govenor signs the bill, it would go into effect immediately.
