McCahren began to wrestle around jokingly after arguing about a paintball game. He said McCahren then got a semi-automatic shotgun, walked into the kitchen area and pointed it at him, according to the arrest affidavit filed by a detective.
• The witness said he heard the gun click, then saw McCahren take a shotgun shell out of a drawer, load the gun and point it at him again. The teen said he then heard another click.
• The witness told police he was trying to leave the house through a sliding glass door when Williams stepped between him and McCahren. He said the gun fired, and Williams was hit.
• Pierre Police Chief Bob Grandpre confirmed the argument and the wrestling occurred between the witness and McCahren.
• Grandpre said the department had an extra officer at Riggs High School on Wednesday and Thursday, more to answer students' and teachers' questions than to provide extra security.
• Some officers know the teenagers involved because the boys were involved in anti-drug programs run by the department, Grandpre said.
• "It's a real close-knit community. It's a smaller community, so we feel these things pretty deeply," Grandpre said.
• Pierre School Superintendent Kelly Glodt said school counselors and others were available to talk with students, but classes went surprisingly well Wednesday and Thursday. School officials appeared to succeed in keeping school activities as normal as possible, he said.
• However, students who were close to the three boys involved in the shooting are having a tougher time dealing with the incident than other students, Glodt said.
• "This is not something that's going to go away immediately. We're going to be dealing with it for quite some time," the superintendent said.
