What's the Matter With Kingsville?

I found the following at www.christusspohn.org/locations_kleberg:

"CHRISTUS Spohn Hospital Kleberg

CHRISTUS Spohn Hospital Kleberg resides in the heart of a town known for its ranching history and rich Texas culture: Kingsville, Texas. Licensed for 100 beds, the hospital is a general acute-care facility offering complete medical and surgical services including pediatrics, obstetrics and skilled nursing, as well as emergency, intensive care, cardiac and comprehensive diagnostic services. The emergency department is designated as a Level IV trauma center."

I'd still like to know why they took the critically injured man Cheney shot to Christus Spohn hospital in Corpus Christi 45 miles further instead of Christus Spohn Hospital in Kingsville, which was nearby? And why did it take them 3 hours to do so?
