That is horrific. I don't think it's helping that the police are not providing any information. You are right, no place is really safe. Keep your eyes open and your gun close.
I used to live in this complex when I first moved to Sacramento. It's an interesting spin on the story by the reporter. It's not until the end that they mention the 3 "victims" were the aggressors.
Detectives say witnesses told them that three men confronted the 26-year-old man outside a second-story apartment and a fight began.
The man retreated into his apartment, causing the trio to break in and continue the assault. During the fight, the suspect picked up a handgun and shot all three.
