The lawsuit alleges the parents of the 13-year-old shooter "should have known."

"I'm not killing myself. I have to take other people's lives before I take mine," the suspect said in a video filmed on the day of the shooting.

Less than two months after they were wounded in the shooting at Noblesville West Middle School, Ella Whistler and Jason Seaman took center stage at the Noblesville Fourth of July Parade.

Noblesville Mayor John Ditslear announced Saturday that Noblesville West Middle School student Ella Whistler and seventh-grade science teacher Jason Seaman have agreed to take part in the parade.

In a statement released Monday, the family of 13-year-old Ella Whistler detailed her life-threatening injuries for the first time.

Ella Whistler, 13, is being treated for gunshot wounds at Riley Hospital for Children in Indianapolis.
