An arrest has been made in the death of NFL star Steve McNair.

Nashville police have taken Adrian J. Gilliam Jr. into custody as the man allegedly responsible for selling Sahel Kazemi the gun she used to kill her lover and then herself.

Kazemi, McNair's mistress, reportedly purchased the weapon for $100 on July 2, two days before she took her own life in a horrific murder/suicide.

Prosecutors are expected to announce the charges against Gilliam later today.
