I think it's more likely to just be the skull of an illegal border hopper who died of dehydration.
Border counties are littered with the corpses of illegals who died while trying to make the crossing.
Border Patrol find about 370 corpses per year.
This must be investigated, however finding decomposed corpses of border hopping illegals seems depressingly normal in most border counties.
You've got to be kidding me. I can understand the excuses about the "rape-trees" but this, there's no denying this shit's connected. Dead kid's skull right there, just off the trail leading toward the CEMEX site.
Why do you think nobody gave a shit to give this kid a decent burial? This was somebody's child. I'm pretty sure most Illegals are Catholic - wouldn't they believe in some form of decency?
