Once again, I'm on a different page/chapter (?) than everybody else, hope nobody minds too much. Something has been bothering me for a couple of days now, and I haven't seen it mentioned yet - although with connection problems, I may have missed it. Her brother said he dropped her off from work at about 5:30, and he tried to contact her the next morning to see if she needed a ride home that day. That sounds to me like she normally has a ride to work, but sometimes needs a ride home. If that's the case, I'm wondering who usually took her to work, and why that person didn't mention something being wrong when she wasn't there and hadn't called saying she didn't need a ride. I'm sure there's a good explanation or LE would have already shown interest in the person.
I live in a town 10+ times the size of Brooklyn, and we have no real public transportation (you have to schedule a ride ahead of time for the small bus service we have and the taxis are few in number and expensive). If she was going to walk/run to or from work, it would make a lot more sense to have a ride in the morning and hoof it on the way home. Has this been brought up at all yet?
