Charlotte, NC-- The mother of a teenager killed four months ago in a shooting in Columbus County is urging prosecutors to press charges.

Carletta McNeil held a news conference Friday in Charlotte, telling reporters her 16-year-old daughter was killed in a racially-motivated crime.

Authorities say Jasmine Thar was visiting her godmother and a friend in Chadbourn when all three were shot by a single bullet from a rifle, killing the teen.

The man who fired the rifle says he was taking the gun from its case and it fired without him pulling the trigger.

The FBI's civil rights unit is investigating the shooting. The victim's family says a local prosecutor told them they turned the case over to the FBI because of evidence found in the shooter's home
