Ok Gigtu. Really close. The street Wyandotte is not marked on any street signs. The handler said Mari walked partway down Wyandotte but we were not sure exactly where she was referring to...I thought maybe it was further down Lindley. After seeing it on your map, these is what I have come up with.
The green line indicated Mari's path of travel. Out of GW, down the strip along the sidewalk close to the building (although my lines are in the parking lot) then into Jon's. Out the front door of Jon's, then cut across at an angle to the front door of the church (there is a fence there, that's pretty much the only way to that entrance and we know she went in there). Then out the side door to the back left of the parking lot. See the little roundabout...it's just a little dead end (full of needles and drug paraphernalia) BUT that entire church parking lot is also fenced on the Jon's side. The only entrance/exit back into the parking lot is through that roundabout and back up. Therefore, she had to have gone to the back of Jon's AFTER the church. From there, she cut back across the church parking lot and out at the back corner onto Lindley. She went up a little further than what my map shows but not much. She then doubled back down the same side of the street and cut across to Kaiser. On the map, I drew the green arrows just going in one door out the other, but she could also have walked around either side of the building...although the side next to Lindley would be the most probable of the two. Then to the far corner of the parking lot.
The red x's are where we found items that might be hers. We suspected she might have gone out behind Jon's first, where she spent a few minutes, before heading to the church. Now, I am not sure that item was Mari's. Or that theory is still correct and she doubled back to the church also.
The purple dots are where the dogs indicated a hiding/chasing pattern or "holding". There were three. In the church. Right outside the front door of Kaiser tucked by a wall and beside/behind the dumpster.
The blue in the two and a half parking lots are because we are not exactly sure what her exact path was. The dog became "animated" in those two lots and there were "multiple" points of interest. Not sure if this means she criss-crossed, was moving quickly or the dog was just unsure. I know where the entrances/exits are to those lots and have noted where there were more definite type hits.
Does this help at all or just make it more confusing?
After this, I really have to finish up a bit for work and get some sleep. Otherwise, I'll be useless tomorrow.
