17-year-old Clair Davis was shot by 18-year-old Karl Pierson Friday afternoon and is now in critical condition at Littleton Adventist Hospital.

Both were seniors at Arapahoe High School. Students had no bad words to say about Davis who was an active equestrian.

“She is just a really sweet, smart girl,” said student August Clary

It appeared that she was in the wrong place at the wrong time.

“I think she was just a bystander,” said a student.

Students say she and the gunman were both seniors in top classes.

“He’d just have bad days sometimes,” said Clary.

Clary has known Karl Pierson since third grade.

“He would kind of get a little angry with people but I could usually get him to calm down,” said Clary.

He says something was different in Spanish class Wednesday when Karl apparently thought he was locked out of class.

“He just yells ‘I’m not the one who locked the door!’ and everyone was just like ‘who what happened'” said a student.

“He was kind of quick to aggression but I never saw any physical aggression,” said another student.

The Arapahoe County Sheriff Grayson Robinson said that Pierson had threatened the speech and debate coach in the past but no one had known how serious he was.
