NEWPORT NEWS - A grand jury has indicted the mother of a 6-year-old boy who shot his teacher on charges of child neglect and failing to secure her handgun in the family’s home, a prosecutor said Monday.

A grand jury sitting in Newport News charged the boy’s 25-year-old mother with felony child neglect and a misdemeanor charge of endangering a child by reckless storage of a firearm, Commonwealth’s Attorney Howard Gwynn said in a news release.

The Associated Press isn’t naming the mother to shield the identity of her son.

The boy shot first-grade teacher Abby Zwerner on Jan. 6 inside her classroom at Richneck Elementary School. Police said the boy’s mother legally purchased the gun. Her attorney, James Ellenson, has said the gun was secured on a top shelf in her closet and had a trigger lock.

Mr. Ellenson said Monday that his client plans to turn herself in later this week. He did not comment on the indictments, which were first reported by the Daily Press.

The decision to charge the boy’s mother is the latest development to cascade from the shooting in this shipbuilding city of about 185,000 people near the Chesapeake Bay.

“Every criminal case is unique in its facts, and these facts support these charges, but our investigation into the shooting continues,” Mr. Gwynn said.

Mr. Gwynn said his office has petitioned the court to empanel a special grand jury to continue an investigation into any security issues that may have contributed to the shooting.

“The safety and security of Newport News students is of utmost importance. The Special Grand Jury will investigate to determine whether additional charges against additional persons are justified by the facts and the law,” Mr. Gwynn said.

Diane Toscano, an attorney for Ms. Zwerner, said there were “failures in accountability at multiple levels” that led to the shooting.

“Today’s announcement addresses but one of those failures,” Ms. Toscano said in a statement, referring to the indictments against the boy’s mother.

Days after the shooting, school of- ficials revealed that administrators at Richneck Elementary had suspected the child may have had a weapon before the shooting occurred. But they didn’t find it, despite searching his backpack.

At a subsequent School Board meeting, parents and teachers lambasted administrators for what they called a misguided emphasis on attendance over the safety of children and staff. They said students who assaulted classmates and staff often faced few consequences, while Ms. Zwerner’s shooting could have been prevented if not for a toxic environment in which teachers’ concerns were ignored.

In a lawsuit filed last week seeking $40 million in damages, Ms. Zwerner’s attorneys accused school officials of gross negligence and of ignoring multiple warnings from teachers and other school employees the day of the shooting that the boy was armed and in a “violent mood.”

In the lawsuit, Ms. Zwerner’s attorneys said all of the defendants knew the boy “had a history of random violence” at school and at home, including an episode the year before when he “strangled and choked” his kindergarten teacher.

“Our lawsuit makes clear that we believe the school division violated state law, and we are pursuing this in civil court,” Ms. Toscano said Monday.

Virginia’s law on felony child neglect states any parent, guardian or other person responsible for the care of a child “whose willful act or omission in the care of such child was so gross, wanton, and culpable as to show a reckless disregard for human life” is guilty of a Class 6 felony. The charge is punishable by up to five years in prison.

The misdemeanor charge states it’s against Virginia law to “recklessly leave a loaded, unsecured firearm in such a manner as to endanger the life or limb of any child under the age of fourteen.” That charge is punishable by up to one year in jail.

Police Chief Steve Drew has repeatedly characterized the shooting as “intentional.” He said there was no warning and no struggle before the child pointed the gun at Ms. Zwerner and fired one round, striking her in the hand and chest.
