Joint Base Lewis-McChord , Washington ( CNN ) -- It was the middle of the night in southern Afghanistan 's Panjwai district when Haji Naim says he was awakened by the sound of barking dogs and gunshots . Moments later , a man clothed in U.S. military fatigues and a T-shirt burst through the door of Naim 's home and opened fire , hitting him in the neck , Naim testified early Saturday at a hearing for an Army soldier accused in a mass killing of Afghan civilians . `` I said 'What are you doing ? What are you doing ? ' Naim told the court at Joint Base Lewis-McChord , near Tacoma , Washington , during a live satellite uplink from a base in Kandahar , Afghanistan . `` He did n't say anything ... He just started shooting . '' Afghan anger kept U.S. agents from killing scene . Naim and his two sons were among the survivors of the March 11 , 2012 , rampage that military prosecutors allege was carried out by Army Staff Sgt . Robert Bales . Naim 's testimony came amid the fifth day of an evidentiary hearing to determine whether there is enough evidence to support the military 's case against Bales , who faces 16 counts of premeditated murder and six counts of attempted murder in the predawn attack . The outcome of the Article 32 hearing will determine whether Bales , 39 , is court-martialed , and whether he will face the death penalty . Bales has not entered a plea in the case , though his attorneys have said Bales suffers from post-traumatic stress disorder and suffered a traumatic brain injury during a prior deployment to Iraq . Naim 's son , 13-year-old Sadiquallah , testified he was awakened by a neighbor screaming that an American was killing people . The teen said he ran to a storeroom , hiding behind the curtain that covered the entrance way . Still , he said , he suffered a wound when he was grazed in the head by a bullet . `` I saw him once , '' Sadiquallah said of the shooter . That was when he entered the compound and `` shot up the family . '' Sadiquallah 's older brother testified the man was wearing military camouflage pants and a T-shirt , and was carrying a rifle with a flashlight . Stunned friends recall good deeds of suspect . Neither Naim nor his sons identified Bales as the shooter . During testimony late Friday , a relative of some of the victims testified about the discovery of the bodies . Khamal Wazir told the court he found his cousin 's mother on the floor , her body beside the door of the family compound . `` She was shot in the head , '' he said . Inside , he found the bodies of other relatives -- each apparently shot in the head -- piled on top of each other and partially burned . The fire was out when he arrived , though smoke lingered in the house . `` Yes , the bodies were burned , '' he told the court . Two Afghan guards at Camp Belambay , a small U.S. outpost near the two villages , laid out a possible timetable for the attacks . One guard told the court he encountered a man who was walking onto the base about 1:30 a.m. and told him to stop . He said the man approached and said , 'How are you ? '' in Pashtun and went inside the base . Another guard said he saw an American man leaving the base around 2:30 a.m . The man also greeted him in Pashtun , asking `` How are you ? '' Neither guard was able to identify Bales as the shooter . Afghan villagers describe slaying 's horror . CNN 's Chelsea J. Carter contributed to this report .
