Alexis Tubbs was making a casserole when she looked out her kitchen window and saw half a dozen FBI agents pointing guns at her 14-year-old son.
Tubbs' son was playing with his Airsoft gun Monday when FBI agents raided a nearby residence at Mountain Creek Apartments.
The raid - at the home of a widowed woman and her six children, Tubbs said - was carried out to investigate a lead about an associate of Mohammad Youssef Abdulazeez. Tubbs said one of the widow's sons knew Abdulazeez.
A day of tribute, remembrance for the fallen
Puzzling out answers, pouring out grief
An FBI official in the Knoxville field office said Tuesday he couldn't discuss the ongoing investigation.
