Williams had obtained an AK-47-style firearm, which he used in each of the three robberies, prosecutors said.

A day after the second robbery, Williamsโ€™ wife, Jessica Sweeney Williams, purchased a handgun.

James Williams used that handgun, as well as the rifle, in the third robbery.

James Williams fired one of the guns during the third robbery but no one was struck by the bullet, prosecutors said.
