Davis and Brown were taken into custody Monday night at a short-term rental property close to where Saturday's shooting erupted, according to police. Davis was allegedly carrying an assault-style rifle with a loaded extended magazine at the time of his arrest, authorities said.
In April, Davis was convicted of robbery, felony gun possession and felony drug possession charges, according to police. He received a 10-year probated sentence to the Community Corrections Program, according to the Nashville police.
"The shooters had no regard for human life and put a crowd of innocent persons, including children, in extreme danger. The entire criminal justice system must treat violent gun crime with the seriousness it demands with resulting incarceration for those convicted," Police Chief John Drake said in a statement following the arrests.
The shooting unfolded around 5 p.m. local time at an off-campus homecoming celebration event, several blocks east of the Tennessee State campus.
The shooting left a 24-year-old man dead, police said. Of the nine people injured, three were juveniles ranging in age from 12-14 years old, police said.
Five victims were taken to local hospitals via ambulance. Five others were transported by private vehicle, according to police.
