The murderer wpi;d be at least as pretty were she smiling in that picture like the victim is smiling.
The victim was on student council, robotics club, color guard, and in several other substantive groups. She appeared to be an achiever and I would not doubt in the least she was an A student. She seemed like the type of student any teacher would love to have in their classroom. The perp, on the other hand, appears to be trouble. I can almost tell the story of what transpired without actually knowing the story because its all too common, and it involves a good girl who got mixed up with a bad boy who was the boyfriend of a bad girl who got provoked into attacking the new girlfriend by the boyfriend because it stoked his ego.
