That makes sense, especially if her garage door faces the street like the front door does. It might be easier to navigate while using her cane (or walker if she uses one). Again, I've missed a lot because this thread has gotten huge quickly.
Just struck me as strange that she entered through her garage, but the abductor(s) brought her out the front door (as evidenced by the blood found). Her home isn't exactly close to neighbors where they would hear the garage door go up/down, is it?
I'm probably overthinking it.
IMO.
