WATAUGA COUNTY, N.C. (WGHP) — A ballistic helmet likely saved the life of a Boone police officer during the deadly standoff in Watauga County on Wednesday.

K-9 Deputy Logan Fox and Sgt. Chris Ward were responding to a home off Hardaman Circle for a welfare check at 9:44 a.m. Wednesday.

They were trying to find someone who didn’t show up for work on Wednesday. Both were fatally shot when they entered the home.

During an initial rescue attempt of the deputies, one Boone police officer was hit by gunfire. The Boone officer was protected by his ballistic helmet and was uninjured, according to the Watauga County Sheriff’s Office.

On Thursday, the sheriff’s office released a picture of the officer’s helmet, showing where a bullet made impact.
