Twenty-year-old Mackenzie Glade Hunter also will serve 36 months of supervised release.

Hunter apologized in court, saying, "It's really bad that I was even involved in it. I wish I hadn't sold that gun."

Before imposing sentence, U.S. District Judge Dale Kimball denied a request to delay the hearing, as sought by the parents of a woman fatally shot with the .38-caliber Smith & Wesson.

In a motion filed this afternoon, Sue and Ken Antrobus of Cincinnati asked Kimball to give them three weeks to try to overturn a ruling that their daughter is not considered a victim of the illegal sale.

The two had requested the designation under the federal Crime Victims' Rights Act. They hoped it would allow them, as their daughter's representatives, to ask Kimball to impose a stiffer sentence on Hunter.

Hunter entered court for today's hearing in a gray and white jumpsuit, giving a thumbs up and waving to his parents.

He had pleaded guilty to two charges in connection with his sale of the gun to Talovic, who killed five shoppers and injured four at Trolley Square mall. Vanessa Quinn, 29, was the only one killed with the handgun.

Prosecutors contended the gun was stolen and sought the enhanced term of 15 months; Hunter's attorney wanted up to nine months, saying Hunter bought the gun from the owner's son.

The Antrobuses wanted to argue for a 99-month sentence.

However, Kimball ruled that Quinn was not a victim of the gun sale that took place about eight months before her death and declined the parents' request to speak at the sentencing.

The judge also has denied the Antrobuses' motion for access to documents in Hunter's case that they believe would show a lengthy prison term is appropriate. On Friday, a three-judge panel of the Denver-based 10th U.S. Circuit Court of Appeals upheld Kimball.
