April 20 (Reuters) - Authorities in Alabama on Thursday said they had made two more arrests in connection with last week's shooting at a "Sweet 16" birthday party that left four people dead and 32 others wounded.
The Alabama Law Enforcement Agency said in a written statement that Willie George Brown Jr., 19, of Auburn, and Johnny Letron Brown, 20, of Tuskegee, were both arrested on Thursday, bringing the total number of suspects arrested to five.
The other three suspects arrested are: Ty Reik McCullough, 17, and Travis McCullough, 16, both from Tuskegee; and Wilson LaMar Hill Jr., 20, of Auburn.
The shooting followed separate outbreaks of deadly gun violence in Tennessee and Kentucky that prompted local leaders to call for tighter gun control measures.
The nonprofit group defines a mass shooting as any in which four or more people are wounded or killed, not including the shooter.
