So, my teachers Husband is Murdered, am i supposed to call her up and console her or something??

Her first Husband died a long time ago and this was her second marriage to a much older guy. He was rich and used to lend money to people. A few days ago he asked back money from a guy who borrowed it from him and threatened that guy as well. So yesterday evening, that guy came to his house to ask him for a few more day's time to repay. He didn't agree and the guy stabbed him to death. My teacher wasn't home then and when she returned, she found her husband dead, in a pool of blood.

So...... she isn't that sad or anything. She was my class teacher in 5th grade.I am wondering weather i should call her or something.i don't know what i should say even.
