Brown was an intelligence analyst who was found unresponsive July 20 in a car on Bragg. Investigators haven't released any details surrounding his death.
The Article 32, similar to a civilian grand jury, will continue Saturday at Fort Bragg. The prosecution rested its case late Friday.
A witness testified Friday that the 27-year-old Brown complained about the price of beer and got in a fight at a bar before the seven soldiers, members of his own unit, punched, kicked, choked and restrained him. He later died.
The seven soldiers were charged with involuntary manslaughter, which has a maximum 10-year sentence.
The trial is being currently being held for five of the soldier, the other two soldiers are scheduled to appear Feb. 27. The division commander will then decide whether to convene a formal trial, or court-martial.
The seven men are assigned to the division's Headquarters and Headquarters Company, as was Brown.
The division identified the soldiers charged as Sgt. Christopher Mignocchi, 22, of Hollywood, Fla.; Sgt. Kyle G. Saltz, 25, of Richland, Wash.; Sgt. Justin A. Boyle, 28, of Rocky Point, N.Y.; Spc. Ryan Sullivan, 23, of Mount Laurel, N.J.; Spc. Joseph A. Misuraca, 22, of Harper Woods, Mich.; Spc. Charles B. DeLong, 24, of Dade City, Fla., and Pfc. Andrey Udalov, 21, of Brooklyn, N.Y.
The soldiers also face charges of conspiracy to commit battery.
