mamamia, from your photo on this post, I think the Cooper St. house is the one just below the Celis' home. See where the yellow line ends and you can look up and see the Celis' house? I think the dog hit there. It's right where the video of the 5 walkers was. The video of the guy lurking in the shadows.
It doesn't look like Prof is on line right now, but when she returns I bet she'll clarify.
ETA here's the video and part of the caption: "They may have been walking in the direction of or directly to East Cooper Street"
