It doesn't make sense

I'm still trying to wrap my head around a senseless violent act that occurred in my little town. Someone I know was murdered. It was in the middle of the day and some punk 17 year old kid stabbed her to death in her own front yard. She lives right across the street from the Middle/High school my boys attended. They are friends with her daughter. This young girl is now trying to understand why. We are all trying to understand why. Marilyn didn't have much. Nothing that was worth stealing and definitely not worth murdering someone over. The details are still sketchy. One of the coaches from the high school witnessed her struggling with a young kid. The coach alerted the school resource officer and they went to help Marilyn. The kid took off running. It took three blocks but the officer caught him. Life Flight landed at the high school, which was immediately put on lock down. Marilyn died on the way to the hospital. The speculation is that the kid was trying to steal her car. I don't know if he was a student or if he is telling the truth to the cops. He has been arrested. He received cuts to his hand during the incident. I hope it gets infected and he has to suffer.

This is just so stupid. I am sick and tired of all the violence in this world. Why can't people just get along and help one another? What ever happened to following the Golden Rule? Why is this 23 year old girl having to help make funeral arrangements for her mother? Children are supposed to bury their parents but not at this young age.
