So they may look close on the map they’re not that close to each other those two addresses however I lived on appeal is blocked at the time of the disappearance and there was a sex offender living on the same street who was targeting children in that age group. I’m not sure if anyone ever investigated that matter as for the ice cream truck I was told that they never found the driver because the Mr. softies trucks or privately owned and they have no way of knowing who was in the neighborhood at the time I agree that if they picked up the sent all the way to Metro North that she must have been on foot and not in a car however we don’t know with Home and the sightings at the video store seem unlikely it’s possible that whoever took her got her onto a train to get her far away quickly perhaps there was some pre-planning...
It's frustrating because, you're right, the two addresses aren't exactly close together... but they're not that far apart either.
Here's a map of the distance between the residences of Equilla (E. 194th & Briggs) and Jeremiah (2111 LaFontaine Ave), via E. 194th & Webster, where Equilla's scent was last picked up, by the Metro-North tracks. It's less than half-an-hour on foot—totally doable for someone who likes to walk, especially in the summer when it's light out till around 8:30 p.m. Could it have been someone that lived in between those addresses?
The scent thing bothers me a bit. Although the Fordham train station is about two blocks away, I doubt a kidnapper would've taken a kid aboard a train where there would be witnesses. August 12, 1985 was a Monday so there could've still been people commuting home from later shifts in the city.
I feel like the only reason a kidnapper would go there is to dispose of a body. As we observed in the Carlos Diaz thread, Metro-North runs "underground," meaning at a lower level than the regular sidewalk; it's not covered. It's also not a closed system, like the subway. Tickets are marked on board Metro-North trains so anyone can enter the station, and from there walk to the trees and bushes that separate it from the street. Here are some pictures to show what I mean.
As for Jeremiah, there was a park nearby where his remains could've been disposed of, assuming this is what happened. And, of course, the Botanical Gardens to the east could've also been chosen to discard remains.
