exactly, and look at the time of day the perp chose to commit the crime - 7:30AM on a week day. this says to me he did care about who was around - he waited until her parents were gone and from what we've gathered on most days cb would have been gone as well. on top of that, if cb's timeline is accurate, the perp wasn't in a rush. it also says to me that this is someone who planned this out. given that she's a young woman with an active social life, i would be willing to bet there would be other opportunities to grab her (leaving a party, driving home at night, stopping for gas, etc) but the perp chose a really tight window of time (her parents leave at 7:00ish, she leaves 30 - 45 minutes later). he had no way of knowing if she'd leave early that morning or if her parents would leave late but he still went for that specific opportunity as opposed to other situations in which there might have been an opportunity to grab her. again, imo, this speaks to someone who knew her routine, who had watched the pattern of the family, and who was confident that morning that his plan would work. it also says to me that this is someone who wouldn't be missed by family or coworkers at 7:30AM on a week day but who might not have that same opportunity late at night or on a weekend.
