Gov. Haley Barbour has signed into a law a bill that requires the state to preserve biological or DNA evidence gathered in felony investigations.
Many law enforcement agencies across the state gather DNA during investigations, but the samples aren't always preserved.
The bill goes into effect immediately. It requires the evidence to be maintained by either by the Mississippi State Crime Lab or local law enforcement.
Among the bills signed by Barbour Monday were those that would:
-- grant visitation rights to grandparents who cared for a child for an extended period of time while the child's parent was in jail or serving military duty.
-- make it a misdemeanor for a person under age 21 to show false identification to purchase alcohol.
