The Last Postal Shooting

The last postal shooting that gets attention is in 2006 when a woman named Jennifer San Marco walks into a post office in Galletta, California with a handgun and she shoots six people. To this day, the deadliest shooting ever carried out by a woman has not been solved. The most chilling detail from this is that there's a guy who is listening to his headphones, doesn't hear the screaming, the shooting, the running, anything, and she just walks up behind him and shoots him in the head. Oh no. Awful.
