Incident began when police got report that Walmart employee was attacked, statement says

Police: Nine suspects, believed to be from the same family, "immediately" began attacking them

(CNN) One of the nine suspects was killed. Another was shot in the stomach. All eight responding officers were injured, including one 10-year veteran who required surgery.

It's the aftermath of an all-out melee in a Walmart parking lot in Cottonwood, Arizona, a town of 11,000 people about an hour's drive south of Flagstaff.

But details are murky outside of the injury and arrest reports.

What's known, according to the Arizona Department of Public Safety statement released by spokesman Raul Garcia, is that someone at the store called the Cottonwood Police Department a few minutes before midnight Saturday to report that a woman who worked at Walmart "had been assaulted in the store by multiple suspects."

The suspects were in the parking lot when police responded, and they immediately attacked the officers, the DPS statement said. Two suspects were shot, one in the abdomen and one fatally, while one of the suspects shot a Cottonwood officer in the leg, according to DPS.
