The mother, Deja Taylor, faced up to five years in prison. This sentence is greater than the original plea deal with prosecutors for a reduced sentence to six months. She is also to serve two years’ probation.

Calls to the prosecutor to confirm the sentencing and a call to the defence attorney seeking comment were not immediately returned to Reuters.

Taylor, 26, whose son shot his teacher Abby Zwerner at Richneck Elementary School in Newport News, previously pleaded guilty to gun charges in a separate federal case and was sentenced to 21 months in federal prison in November. As part of the state plea deal, she can serve her state sentence concurrently.

According to police, the boy had taken the 9mm pistol from his mother’s purse, hid it in his backpack and took it out while Zwerner was teaching class, firing a single shot through her hand and into her chest.

Zwerner survived the wounds and was hailed as a hero for evacuating students from her classroom.

Zwerner’s lawyer, who filed a US$40 million lawsuit against school administrators on her client’s behalf, has said that Richneck Elementary officials had been warned three times the day of the shooting that the boy was armed.

Zwerner has not returned to the classroom, media accounts say.
