The mother of the 6-year-old Virginia boy who used her gun to wound his teacher, Abigail Zwerner — boasting, “I shot that bitch dead” — pleaded guilty Tuesday to a felony charge in connection with the shocking case.

Deja Nicole Taylor, 26, pleaded guilty to child neglect, a class 6 felony that carries a maximum of five years behind bars, Newport News Commonwealth’s Attorney Howard Gwynn said in a statement to The Post.

In exchange for her plea, which avoids a jury trial, prosecutors agreed to drop a misdemeanor charge of reckless storage of a firearm and ask for a sentence within state guidelines, which is up to six months.

However, Circuit Judge Christopher Papile has the authority to give the maximum of five years when Taylor is sentenced on Oct. 27, the Daily Press reported.

“The Court has ordered a pre-sentence report and the Commonwealth will not ask the Court to deviate from the sentencing guidelines,” the statement said.

“Ultimately any sentence of incarceration and any terms of probation or other conditions of the sentence will be decided in the sole discretion of the Judge,” he statement added.

Without the agreement, Taylor faced up to six years in the slammer — five on the child neglect count and another year on the firearm access charge.

“We are thinking of Ms. Zwerner and all the students and faculty who experienced these events as our office continues its investigation,” Gwynn said.

“The safety of our schools is of paramount importance, and we will continue to support the victims as they work through the effects of this incident,” he added.

Taylor has also pleaded guilty in federal court to using marijuana while owning a firearm, which is illegal under US law, and lying on a federal background check form when she bought the weapon.

The federal charges carry up to 25 years combined, but prosecutors have agreed to ask for between 18 months and two years. Sentencing on those charges is scheduled for Oct. 18.

Taylor’s defense attorney, James Ellenson, said Monday that Papile would be able to take Chief US District Judge Mark Davis’ federal sentence “into consideration” and could decide to run the two terms concurrently.

“We don’t want any incarceration, but if we have some incarceration, then we would probably prefer that it happened in the federal system,” he told the Daily Press.

“Simply because there’s probably more opportunities for rehabilitation and counseling than might be afforded in the state system,” Ellenson said.

The lawyer sought a deal in which Taylor would plead guilty to the misdemeanor and not a felony, but he said prosecutors held firm on the child neglect count, the outlet reported.

Ellenson noted that prosecutors stressed that the boy gained access to the firearms despite significant behavioral problems that his mom was or should have been aware of.

The first-grader shot his teacher, Abigail Zwerner, at Richneck Elementary School in Newport News on Jan. 6.

“I did it … I shot that bitch dead,” the pint-size pistol packer bragged, according to recently unsealed search warrants. “I got my mom’s gun last night.”

The boy “fired one round that struck Zwerner in her left hand and upper torso,” an affidavit states.

The 25-year-old teacher, who suffered a collapsed lung and other grave injuries, has filed a $40 million lawsuit accusing school officials of ignoring multiple warnings about the student leading up to the incident. She has since resigned.

Ellenson has said Taylor believed her gun was secured on a high closet shelf with a trigger lock, adding that it was unclear how her son got ahold of it.

The attorney has said his client faced mental health issues after having an ectopic pregnancy and miscarriage.

He recently told CNN that Taylor’s son, who is now in the custody of his great-grandfather, Calvin Taylor, “had extreme emotional issues, and we are all working to see that he improves every day.”
