The measure originally called for collecting DNA from anyone arrested for a felony. But the latest version approved Tuesday would restrict collection only to those people arrested for violent felonies like rape and assault.
It previously cleared the Assembly and now goes to Gov. Scott Walker.
The DNA collection law takes effect in April 2015. It also will require DNA to be taken from anyone convicted of misdemeanors. Current law requires DNA collection only from convicted felons and sex offenders.
The DNA collected would go straight to the state crime lab, rather than be kept by local police.
