Live from NPR News in Washington, I'm Shay Stevens.

Authorities are reviewing social media postings by the 23-year-old gunmen who killed two people and injured 18 others at the Catholic School Church in Minneapolis.

Investigators say the assailant was a former student who idolized mass killers.

NPR's Jason DeRose spoke with a young survivor of

Wednesday's attack. Right. Rosie Stiggy is eight years old. She just began third grade and was sitting

with her class yesterday morning during the first mass of the school year. So we were like just in the

middle of mass and then like big like the big, like, the sounds went on.

And then it was, like, really smoky.

And we all had to, like, run to preschool rooms.

And the police came and got him.

Meanwhile, an 8-year-old Fletcher Merkel and 10-year-old classmate Harper Moiske were killed in the attack,

Merkel's father says he wants his son to be remembered for the person he was and not the act that ended his life.

And as NPR's Windsor Johnston reports, the Minneapolis shooting is renewing fears over school safety.

Children were inside the church when the gunfire began. Some were praying. Others were hiding.

Now families are being forced to explain why a place that was supposed to be safe suddenly wasn't.

Psychologist Melissa Brimer advises parents to check in with themselves before talking to their kids.

Take that breath, acknowledge that what feelings are coming up, and then have that

conversation with your child about first what have they heard about the event, and what do

they need before they go to school? Mental health experts say it's crucial to let children

talk, ask questions,

and feel what they feel, especially when violence hits close to home. Windsor Johnston, NPR News.
