A young woman who killed an intruder may be heading to prison, even now that authorities have ruled the shooting justified.

In December, Krissy Noble shot a man named Dylan Stancoff with her husband's gun when Stancoff forced his way into her Fort Smith, Arkansas, home. Noble was 11 weeks pregnant. The case was sent to the Sebastian County Prosecutor's Office, which determined that the shooting was justified.

But Noble still faces felony gun charges because of a previous drug-related conviction. In 2017, Noble pleaded guilty to felony possession of marijuana with intent to deliver as well as possession of drug paraphernalia. (She had been pulled over while riding in a vehicle with friends. Each person in the vehicle received the same charges when no one claimed the items.) She got a five-year suspended sentence, and as part of that was prohibited from either possessing or using firearms.

After Stancoff's death, the authorities filed a petition to revoke Noble's suspended sentence. She has since been charged with being a convicted felon in possession of a gun. Yesterday Noble turned herself in, was booked, and was released on a $2,500 bond.

Noble gave birth to her son earlier this year. If convicted, she tells ABC News, she could spend a maximum of 24 years in prison. "That's my baby's life," she lamented. "I won't even know my child."
