Virginia ? The college student dubbed the “cell phone bandit” was sentenced to 12 years in prison Friday for robbing banks while chatting on the phone with her boyfriend.

Candice R. Martinez, 20, told the judge she was still unsure what prompted the crime spree.

Martinez tearfully apologized to the bank tellers – two of whom were in court.

Martinez gained notoriety after one of the four robberies was captured on a surveillance video. In a tape broadcast around the world, she was seen calmly talking on her cell phone while a nervous teller complied with typed instructions demanding cash.

U.S. District Judge Gerald Bruce Lee sentenced her to five years for conspiracy to commit bank robbery and seven years on a firearms charge. In one of the robberies, Martinez pulled a .38 caliber revolver.
