A decade of death

Crossing the border illegally in the searing summer heat is lethal — about 2,000 bodies have been found in Southern Arizona's desert since 2001.

Few carry identification, and the effects of the sun and animals leave many bodies unrecognizable.

Figuring out how they died is the easy part — in most cases their internal temperatures rose so high they became delirious, fell unconcious and died. But determining who they were is a difficult, often gruesome task, that has transformed the Pima County Medical Examiner's Office.

There are so many bodies that taxpayers are paying for more staff and an extra storage cooler.

Summer, when the dead arrive daily, pushes the forensic scientists to their limits as they try to solve each mystery, and find answers for families desperate for word of their missing loved ones.

The special section that ran as a print exclusive Sunday is now available to online readers.
