Nevada Governor Brian Sandoval signs Brianna's Law on May 29, 2013.
CARSON CITY, Nev. (AP) - After clearing the state Legislature on its second try, Brianna's Law is now Nevada law.
Republican Gov. Brian Sandoval signed SB243 on Wednesday as dozens of family members and friends of the law's namesake looked on.
It passed the Senate unanimously and cleared the Assembly by a single vote earlier this month.
The bill mandates a DNA cheek-swab whenever a person is booked for a felony arrest. If the arrest is deemed legitimate, the DNA would be cross-referenced with DNA from other crime scenes to see if the arrestee was involved.
The proposal is named after Brianna Denison who was raped and murdered by James Biela in Reno in 2008. Proponents believe such a law may have saved Denison because Biela had a prior felony arrest.
