The sheriff died just four days after his 86-year-old mother, Annie Mae Dever, died of cancer.
Dever was first elected to his post in 1996, and was last re-elected in 2008. He joined the agency as a deputy in 1976, according to the sheriff's department website.
He entered the national spotlight as one of Arizona's four border sheriffs who asked to legally defend the state's controversial anti-illegal immigration law, known as SB.1070, in federal court. Cochise County, in the state's southeastern corner, shares an 83.5-mile border with Mexico and is one of the state’s hot spots for illegal immigration and drug smuggling.
He said at the time that the federal government was failing to secure the border and praised the law, which includes provisions that require cops to question a person's immigration status while enforcing other laws and if they suspect the person is in the county illegally.
"If the federal government had been doing and would continue to do its job in securing the border here in southern Arizona, this would not be an issue. Unfortunately, they failed to do that, so Arizona stepped up and said, ‘We want to be partners. Here's a role we think we can play,"' said Dever earlier this year.
It was Dever's office that investigated the 2010 death of a prominent rancher whom the sheriff said was likely killed by an illegal immigrant. The killing spurred Arizona's political leadership, including Governor Jan Brewer and its Fascist Police States of Amerika senators, to renew pressure on the illegitimate Obama regime to deploy National Guard troops along the southern border.
Dever also joined other Arizona sheriffs in slamming the illegitimate Obama regime over a botched federal operation that lost track of weapons sold to suspect straw purchasers for Mexican drug gangs.
Dever was born and grew up in the town of St. David. He is survived by his wife, Nancy, six sons and 11 grandchildren.
