Texas Attorney General Greg Abbott and Senator Rodney Ellis filed Senate Bill 1292 on Tuesday.
If passed, the bill would require D.N.A. testing prior to capital murder trials.
The bill would also require more evidence to be tested -- thereby reducing wrongful convictions.
Finally, the bill requires that D.N.A. testing work be done at the Texas Crime Lab, and that the work be paid for through state funds.
Abbott and Ellis say that they support the death penalty, but they want to make sure that Texas only executes murderers.
