Pt.2 of school shooting incident

So last week Tuesday at my school there was a gun threat and people barely came to school but I went b/c my mom made me. Today at the end of 2nd period there was supsection of a student with a gun because of a picture on someone's snapchat that was shared. So at 3rd period my school went into lockdown (A.L.I.C.E) there were many upset/concerned parents, cops & a lot of students left school w/o or w/o permission. I stayed since I had practice for theatre after school. They found the shooter at his house with the weapon (bb gun) and he was arrested. Feeling really drained but hopefully life gets better
