Assemblyman Paul Cook, R-Beaumont, introduced AB 885, which would have forced the state's worst offenders to get a special driver's license with coding in the magnetic strip that could alert police to their status as "sexually violent."
The bill failed in committee after it was introduced this week, but Cook is vowing to reintroduce it.
"I'm disappointed that the bill didn't pass, but I'm not deterred," Cook said. "Requiring the worst sex offenders to carry ID would be of great help to law enforcement in the early hours of an abduction of a child. We have a long way to go in keeping kids safe."
The bill missed advancement by two votes. Four Republicans and two Democrats voted for the bill, while the committee chair and another Democrat opposed it. Five Democrats and one Republican did not cast a vote.
The bill has been endorsed by Maurice Dubois, whose 14-year-old daughter Amber was raped and murdered by convicted sex offender John Albert Gardner III in February 2009.
