What about Georgia's statute of limitations?

My whole life I've heard of the "statute of limitations" and I've always understood that "after 7 years" a person's warrants for arrest and bad debt were history. I've always heard stories of child molesters who got away with their bad deeds because it was "too late" for the victim to report them... after 7 years. So, anyway, a woman I work with just got arrested on Saturday for writing a check for $13 which she did not have in her checking account way back in 1994!!!!! She got pulled over by a cop when she accidentally ran off the road while driving (we work night shift) and the cop told her there was a warrant for her arrest because of that bad check she wrote in 1994! Yep, she was arrested and went to jail and had to pay a fine and still has a court date. Unbelievable that she's having to go through all that for $13! So, the question is, what the heck is the "statute of limitations" for things in Georgia? Where do I go to learn about this stuff anyway?
