I am not sure...I was doing some news search...Let me take a look...
Every map I've seen places the Mitchells closer to Bonita Circle than the La Sombra and Buena Vista location of the alleged sighting. Looks to be quite a distance. Early reports had the Mitchells living at the intersection of La Sombra/Buena Vista but according to these maps, they aren't even close.
Map Stick pin is 231 Buena Vista
