The sense of relief went away by Monday afternoon, Jan. 29. Alexander Vue attending his morning classes at James Madison Academic Campus and had lunch with his sister.

"They walk different paths, so he patted her on the back and said 'I'm going to go this way' and that's the last time she's seen him as well," Xiong said.

The school's principal said they're following policy and cooperating with police, but on a personal note, said this is troubling, and Vue is a good kid who is always smiling.
