The 40-year-old Hartford City woman was sentenced Tuesday after pleading guilty last month to dangerous control of a child. The charge refers to cases where a parent or guardian permits a child to possess a firearm.
The Star Press reports she acknowledged to investigators she was aware her son had a firearm, but never discussed the matter with him.
The boy, who had been in trouble related to guns before, took the weapon to Blackford High School on Oct. 30, resulting in a lockdown and a delay in dismissal of students that day.
The Associated Press isn’t identifying the woman to avoid identifying her son.
