Agree. Convenient.Although LE said that she was shooting randomly. Also, this pastor and daughter weren't at the school and church years ago when the shooter was a student there.
JMO, but I think it was random and she was not targeting indivdiuals at the school. Just a convenient place for her to carry out her plan.
A big bang for the buck.
The murderer wanted to make a mark and punish society....and what better way than slaughtering little children. Imho
