Unless there is a condition of bond that prohibits you from relocating, yes you can move. However, it is imperative that you keep the court and your bondsman notified of your current address at all times.
What you describe is an armed robbery. I encourage your girlfriend to seek out competent counsel at her earliest convenience. You or her family may have to assist as it may be awhile before she is taken before a Superior Court Judge for a bond hearing.

However, I would strongly urge you to speak with an attorney regarding the matter so that all of your options are fully explored.
