The wife and a friend of former Arizona Gov. Raul Castro are calling for changes in Border Patrol procedures after agents recently detained the frail 96-year-old in 100-degree heat for more than a half-hour.

Castro said he was traveling from his home in Nogales, Ariz., to celebrate his 96th birthday in Tucson when his vehicle triggered a radiation sensor at the Border Patrol checkpoint on Interstate 19 north of Tubac.
