I live in Phoenix Arizona & my husband just got charged with armed robbery. He got caught with an accomplice who ran off & got caught later on, he stayed didn't attempt to run or anything, he has been cooparating with the cops in everything. Also the weapon they used was a fake toy gun, nobody got hurt in the process, he has no prior criminal history, this is his first offence. What's is the minimum and maximum prison time that I should expect him to get? Will getting the help from a good lawyer do any good?
