I am cursed with dial-up that is carried on barbed wire to the rural wasteland. Can you re-cap?
Pretty much what we already know: Derick O'Dell. Shot in upper arm. Was in class, second floor. Shooter came inside classroom, shot a full round. Shooter was a young Asian male, maroon hat, black coat. Said nothing, only shot and then left. Some in critical condition. They barricaded the door to prevent shooter to come back; shooter tried to shoot door down. Shooter left. Police came inside hall, cleared them for ambulance.
