The North Carolina Legislature is trying to work out a compromise to a bill letting investigators collect DNA samples from suspects when they are charged with serious crimes.
The House gave final approval Wednesday night to its version of the measure directing law enforcement to take samples before a suspect is convicted and send them to a state lab. A Senate judiciary committee also agreed to its own bill Wednesday evening.
Civil liberties advocates say taking DNA samples from people who haven't been convicted of a crime are unconstitutional.
Bill supporters argue a wider DNA database will solve more crimes.
Lawmakers have tried to win over opponents with amendments that would remove samples quickly from the database if a suspect isn't convicted.
