The TENNESSEAN reports that the man who sold the gun that killed Steve McNair will be facing federal gun charges.

U.S. Attorney Ed Yarbrough has called a 1 p.m. ET media conference at the federal courthouse in Nashville to formally announce the charges against the gun seller. Police have previously determined that 20-year-old Sahel Kazemi shot & killed McNair before turning the gun on herself. Kazemi reportedly purchased the gun just two days before she used it on the ex-Titans QB.

WSMV-TV has learned the identity of the arrested gun seller: Adrian J. Gilliam, Jr., a convicted felon who is not allowed to sell firearms:

A criminal complaint unsealed Friday in Nashville says that Gilliam — who was convicted of murder and attempted armed robbery in 1993 in Florida — admitted he sold the gun to the woman who later shot McNair.

…

The complaint, signed by ATF agent Mickey French, charges Gilliam with illegally possessing a firearm, which he is barred from doing as a felon.

Detectives traced the gun to its 2002 sale at a pawn shop, according to the complaint. Gilliam eventually bought it from an individual for $100 about a year ago. According to court documents, Gilliam admitted to detectives he sold the gun to Kazemi for $100.
