(CNN) The body of a 6-year-old girl believed to be from India was found in a remote desert area in Arizona this week, officials said.

US Customs and Border Protection said the girl was trying to cross into the United States with a group of people from her country. Her body was discovered 17 miles west of Lukeville, just over the US-Mexico border.

The group was trying to get into the US after human smugglers dropped them off near the Mexico border, the agency said in a statement Thursday. Temperatures in the rugged wilderness where agents found her remains Wednesday hovered around 108 degrees.

Pima County Chief Medical Examiner Gregory Hess identified the girl Friday as Gurupreet Kaur, who was a month shy of turning 7. Her death was accidental and caused by hyperthermia , Hess said.

Border Patrol agents got the information on her movements from two women from India who told officials they'd been separated from a woman and two children traveling in their group hours earlier.
