VIDEO: California Deputies Tell Story of Their Shootout with San Bernardino Terrorists

For three San Bernardino County Sheriff's deputies, the day two terrorists went on a deadly shooting spree Dec. 2, will be a day they never forget.

Deputy Shaun Wallen recalled the moment he came face-to-face with Syed Rizwan Farook and Tashfeen Malik -- a husband and wife team that killed 14 people and wounded 22 others at the Inland Regional Center.

"It was very, very frightening. I was very scared," Wallen said. "I exited the vehicle. Both suspects were firing at me."

The confrontation happened on San Bernardino Avenue, where he and a Redlands police officer engaged in a gun battle with Farook and Malik, NBC 4 reports.
