here. sheriff's deputies in oakland county. there were more than 100, though, 9-1-1 calls that came into the police. and this 15-year-old student. we don't know too much about the student but we know he was a student at oxford high school and that he was using a semiautomatic handgun today when all of this happened. now, i did ask the oakland county undersheriff if he legally had that handgun or if it was maybe registered to a family member. he wouldn't answer those questions yet tonight but said obviously that is part of their investigation. he did tell us there was a search warrant executed on his home. we don't know, yet, what that maybe revealed to them but we are waiting for update in the next couple hours. meanwhile, from those in this community, oxford, a very small, close-knit community, they are worried. they're wondering and they are worried that there were warning signs that this could have happened in their school. now, the undersheriff, though, with oakland county tells me don't believe everything you hear or see/read on social media because there is they are still active investigating this. >> and what do with know about the -- those who were injured?
