Opinions wanted on a Possible Empathetic Connection

Well for the past couple days (mainly over memorial day weekend) I had become really agitated for apparently no reason. I usually don't get real crabby that often but if I do it's only for a few hours or a day at most. I couldn't understand what it could have been. I could almost feel the evil build up in and around me but I didn't really notice the "evil" feeling until it had been too late. Finally today, something happened:

Calumet Rampage Deadly

After these events happened and after the suspect was apprehended (according to the news) I felt the agitation and aggression that was dwelling on me lift off my shoulders in a matter of minutes.

Do you think that this is why I had been feeling so agitated and felt the "evil" surround me? From the reports right after it happened - They were saying three dead and two wounded. It was rather devastating to this small village but the news actually reported only one dead and several wounded so I don't know. Either way, it was a rough time. Also, I think it might be important to mention this all happened a few houses away from mine. Finally, my girlfriend and her mother passed through the area right before the police got there. A passerby did get shot...I fear that if they would've been in the right place at the wrong time, they would've been shot and maybe killed. They got through fine though.
