PHOENIX -- Arizona officials have released the name of an on-duty U.S. Border Patrol agent who was killed in a rollover accident on Interstate 10 near Benson.
Another agent was injured in Wednesday morning's accident, but neither his name nor his condition has been disclosed yet.
The office of Arizona Gov. Jan Brewer identified Alexander Giannini as the officer who died in the crash.
Brewer's office say Giannini was based out of the Willcox Station and had been with the Border Patrol since 2009.
The governor has ordered that flags at all state office buildings be lowered to half-staff from sunrise to sunset Thursday in honor of Giannini.
