"I've seen injustices like this in the news and around the country, but I never thought it could happen to my little brother; he just turned 21 in December," said Kiera Bird.
Instead of standing tall at 6'8", "Tre," as his family calls him, is in the hospital paralyzed.
"He just wants to walk again," his sister said. "He told me if he could just move his arms he'd be happy about that."
Bird was shot in the parking lot of the Deerfield Estates Apartments after being spotted in the back seat of a car with a young girl. Initial reports say the security guard, Ricky Stone, asked for Bird's ID.
Stone says Bird refused and claims Bird tried to back over him.
"We are only seeking justice for him - we are only seeking the best for my son," said his father, Monroe Bird II.
The Tulsa District Attorney says preliminary findings show the security guard was justified in the shooting. In an earlier interview, the Assistant DA told News On 6 the security guard's description of what happened matched up with what they found at the scene.
The family says that's not true, and they hired attorneys Solomon-Simmons and Crump to fight the DA's decision.

"We want a fair investigation done," Crump said at a news conference at Greater Grace Temple.
"This family is only asking for simple justice. They aren't asking for anything extraordinary; they aren't asking for anything any other citizen would deserve."
"If the security guard believed there was some illegal activity going on he should have called the police, and we believe if that would have happened, we wouldn't be here today in these tragic set of circumstances," said stepfather Johnny Magness.
"Families shouldn't have to deal with this. Families shouldn't have to go through something like this."
The family says it's hard reliving what happened that day, but they hope by speaking out, they'll reveal what they say is the truth and find justice for Tre. They say the attorneys can prove that their son wasn't backing up towards the security guard when he was shot, due to the nature of the wound.
We spoke to the district attorney today on the phone, and he says based on the information presented to him, the security guard was justified in his actions; however, if new evidence is presented to suggest otherwise he'll take it into consideration.
He says the door to this case isn't completely closed.
