Court records show officers had responded to the home of a man fatally shot by sheriff's deputies in West Tennessee at least twice before for reports of domestic violence.

The Tennessee Bureau of Investigation says two Shelby County sheriff's deputies fatally shot 48-year-old Jimmy Lee Lawson of Arlington on Saturday night after he confronted them in his driveway and threatened them with a knife.

TBI spokeswoman Susan Niland said deputies were responding to a domestic call at the home.

The Commercial Appeal (http://memne.ws/2hzQrIB) reports court records show deputies had been called to the home at least twice this year for domestic problems and used pepper spray on one occasion to subdue Lawson. During one call, Lawson's wife said he was bipolar and off his medicine.

Lawson was white. The sheriff's office hasn't released the names or races of the deputies, but said both were placed on routine administrative leave.
