LATEST: All four suspects, Arthur Moore, Nadin Hiko, Devonte Wash and Devon Phillips have pleaded not guilty in the murder of Aric Brill. They each face multiple charges including robbery, assault and murder.
Wednesday was the first time Brill's family members were able to see the suspects in person. Brill's mother, Karen Brill-Kelley, says she made it a point to look all four men in the eye.
13 Action News obtained court documents from grand jury proceedings. According to the court documents, one of the men accused of the murder, Nadin Hiko, confided to his cell mate that he was involved in Brill's murder.
According to the court documents, back in 2009, Hiko was in prison for a different crime. He apparently spoke to his cell mate and shared details about the 2009 murder. At the time, the murder had only happened a month earlier.
It took investigators several years to make the arrests.
"I'm just glad to finally look at these creeps and let them know we're not afraid of them," says Aric's father, Donald Brill.
Authorities said the case was reassigned twice and things began to come together over the past few months.
Police say they received tips even 7 years after the murder from witnesses -- people who remained anonymous -- and even information from suspects trying to help themselves.
Police added that they are working to identify and arrest a possible fifth suspect.
UPDATE: Seven years after the deadly shooting of Aric Brill, we're hearing from a witness for the very first time.
"It gets my blood racing," said the man who didn't want his identity released. "It's depressing."
That witness just testified before a grand jury in Clark County. He described how a night out with friends quickly changed.
"I didn't see nobody until guns was drawn and they were in my face," he said.
The man said one gunman fired approximately 17 shots. Brill was killed. A second person was also shot but survived.
The witness said Brill was a brilliant young man who kept mostly to himself. He told 13 Action News that night forever changed his life.
"I socially closed myself out from everybody," he said. "Stopped going out."
The suspects are due in court next week, according to Brill's family members.
LAS VEGAS (KTNV) -- The killers of 16-year-old Aric Brill may finally be brought to justice.
The teenager was killed outside of a house party in February 2009 near Charleston and Nellis boulevards. He was one of two people shot that night during a robbery.
Four suspects were indicted by a grand jury on Thursday.
The suspects are Arthur Moore, Nadin Hiko, Devonte Wash and Devon Phillips.
They are facing charges of murder with use of a deadly weapon, attempted murder with use of a deadly weapon, conspiracy to commit robbery, and robbery with the use of a deadly weapon.
The attempted murder charge is for Joseph Bently, who survived the shooting. Brill was shot in the back of the head as he was attempting to run away. He later died at University Medical Center.
In January of this year, Brill's mother offered a $100,000 reward to anyone who came forward with information that led to the conviction of the person or persons who killed her son.
