JEFFERSON CITY — Gov. Jay Nixon signed legislation Thursday morning adding to the categories of people who will be required to submit DNA samples to authorities.
Missouri already collects DNA from all convicted felons before they leave prison.
The bill is to require DNA samples to be taken from anyone 17 or older who is arrested on suspicion of a violent crime, burglary or sex offense.
The state crime lab would discard a sample if charges were dropped or never filed, or if the person were acquitted in a trial.
Supporters hope the legislation will help catch suspects in unsolved crimes.
Nixon was also to sign bills Thursday that impose new restrictions on sex offenders and ban texting while driving for people age 21 and younger.
