The mother of the Nashville school shooter who killed six people – including three 9-year-olds – appeared to be a gun control activist who once urged friends on Facebook to sign a petition calling to keep firearms out of schools.

“So important!” Norma Hale wrote in a March 8, 2018 Facebook post that she was sharing a petition from the Sandy Hook Promise Foundation that said “Keep Guns Out of School.”

The domain for the petition page didn’t seem to be there anymore.

In another post from February 21, 2018, Hale shared another petition from Sandy Hook Promise that asked lawmakers to “Make Large-Capacity Gun Magazines Illegal.”

Hale’s adult child, Audrey Hale, carried out Monday’s horrific mass shooting at The Covenant School Monday morning.

The 28-year-old, believed to be a former student at the small Christian school, was carrying at least two assault rifles and a handgun, police said.

In other Facebook posts from several years ago, Norma Hale, who seemed to work as a coordinator at The Village Chapel, a church in Nashville, gushed about her two children and their accomplishments.

She also said in an August 2015 post that Audrey “wrote thank-you notes to all her professors at the end of her summer semester,” including one teacher who had lost her son in a car accident the year before.

“These are some of the things she said… “Don’t let anything or anyone take away your happiness. You have a reason and a purpose to be here.’ Hale wrote and added, “Wow, Dre. I love you.”

In other posts, she talked about her son a lot and didn’t hide the fact that she was lucky to have two kids.

In an Oct. 6, 2017 post, she wrote “Just grateful to be the Mom of these 2 awesome kids!” with photos of Audrey and her brother growing up through the years.

“Mother’s Day 2014,” she posted in May 2014 with a photo of her and her two children. “I get to be these awesome kids’ Mom!”
