The criminal case involving a 6-year-old Virginia boy who shot his elementary school teacher earlier this year is now in the hands of the local prosecutor, as police have completed their investigation into the matter, officials said. 

Newport News, Virginia, Police Chief Steve Drew said Tuesday his department had handed over its investigation regarding the January shooting of Abigail "Abby" Zwerner to the office of the Commonwealth’s Attorney.

Zwerner was teaching her first-grade class at Richneck Elementary School on Jan. 6 when her 6-year-old student used his mother’s 9mm handgun to shoot her, police have said.

The case is more complicated because so many of the witnesses were first-graders, and interviews therefore require parents’ permission and assistance from a child psychologist, Drew said.  

Howard E. Gwynn , the Commonwealth’s Attorney, told The police submitted three binders containing evidence and investigative details, in addition to body camera footage of the shooting aftermath.
