GRAND CANYON

Body of missing hiker believed to be found

Authorities say they have found a body in Grand Canyon National Park in Arizona and believe it's that of a Northern Arizona University student missing on a hiking trip.

Search and rescue crews have been looking for 20-year-old Bryce Gillies since Tuesday.

Park officials say a body, presumptively identified as Gillies, was found Saturday morning less than half a mile from the confluence of Bonita Creek and the Colorado River on the North Rim, along with a backpack and personal items.

They say the Coconino County Medical Examiner's Office will try to identify the body and determine the cause of death.

Search crews found Gillies' car Wednesday.

Authorities say he started his hike July 18 with plans to come home Monday.

Gillies' father called park officials Tuesday when his son failed to return.

72 arrested in crime operation in Arizona

The Maricopa County Sheriff's Office arrested 72 people during a three-day crime sweep in Chandler and Queen Creek southeast of Phoenix.

Sheriff Joe Arpaio said the operation started as an attempt to control illegal immigration, but new federal guidelines prevent deputies from arresting illegal immigrants solely for being in the United States illegally.
