A woman who identified herself as a former grade school classmate of the Minneapolis church shooter said that she knew something wasn’t right with him. 

Josefina Sanchez made the admission to KSTP on Wednesday after a 23-year-old born with the name Robert Westman, who later identified as Robin Westman, opened fire at a Mass being held at the Annunciation Catholic Church, which was attended by students from the attached school. The attack left children dead and 17 others injured, 14 of whom were children. 

“Something I knew was off, but I was a kid how would I know like what to do?” Sanchez told KSTP, which reported that she was a seventh-grade classmate of Westman. 

“When you see something erratic, it doesn’t leave your mind so… [Westman] would put up his hand and say like ‘praise Hitler,’” Sanchez added.

“I think it’s actually a spiritual battle,” Sanchez said to KSTP in reference to the video. “I don’t think it’s this world, it’s demonic, I’m sorry, but it is. I think we need Jesus. [Westman] needed him.” 

“I wish I could have said something sooner, but I was little, how do I know?” she also said. 

Police said Wednesday that Westman had no prior criminal record and all the weapons used in the mass shooting were “lawfully purchased.”

“This was a deliberate act of violence against innocent children and other people worshiping. The sheer cruelty and cowardice of firing into a church full of children is absolutely incomprehensible,” Minneapolis Police Chief Brian O’Hara said.
