Keandre Lamont Johnson, arrested in Nashville, faces federal charges for possessing drugs, a modified Glock, and while out on bond, an aggravated assault charge.

Authorities said Montgomery resident Jaquez Myrick, 25, was seen leaving the scene of the shooting. Myrick was allegedly found in possession of a handgun with a machine gun conversion device and was arrested Sunday on a federal charge of possession of a machine gun, an Alabama Law Enforcement Agency spokesman said.

State lawmakers will hold a press conference Friday morning at 10 to address the recent mass shooting at Tuskegee University.
