Alexandria J. Baker Pierce, 23, died in the shooting along N.C. Highway 54 on June 10. Also killed were Amesha Alia Page-Smith, 24, and Adrianne Celeste Stevens, 22.
Eric Smith says he can't believe his cousin is gone.
"She was a fun outgoing energetic person," he recalled. "If you wanted to know the truth she would tell it to you."
According to an autopsy report released Tuesday, Page-Smith was shot four times and her friend, Pierce, was shot 13 times. The women were shot with a .45 caliber handgun while sitting in a car driven by Page-Smith.
"That's a lot of bullets, that's a lot of bullets," Smith said shaking his head.
Police say they believe the women were shot by 23-year-old Brinton Millsap - who then turned the gun on himself. Millsap's body was found near the women's car.
Smith grew up with the women and went to school with Millsap. He says Millsap was quiet, into basketball and not a person you would think could do something so tragic.
"He was just a all-American guy, he played basketball, he was into his books, he wasn't a trouble maker so I can't really see him doing nothing like this," Smith added.
He believes a mental health issue may have played a role in the shooting.
"It is upsetting because if his family knew about his issues or if he was telling somebody or he was reaching out to somebody, somebody should have told somebody," Smith said.
Now, Smith is calling for more awareness in the community and encouraging others to speak up before it's too late.
