My next door neighbor comes over and we're all watching the NHL skills challenge while playing Yahtzee (exciting Friday night I know) and all of a sudden my dog starts going apeshit at the front door. I open it and I can hear someone yelling "HELP! HELP!" repeatedly at the top of their lungs. I look over and two houses down (new neighbors. We thought it was two gay dudes but apparently they're brothers) there is a big commotion with a bunch of people running around. It was dark so all I could make out was their silhouettes. Next I hear someone else screaming "He fucked my wife!" over and over and I can kinda see someone stomping someone else on the ground. Then a large pickup burns rubber away and down the street. I can make out the silhouettes of some guys trying to pick up the someone off the ground while screaming "come on lets get him right now!". At that point I went back inside and about 30 minutes later a cop came to the door and I described what happened and filled out a brief statement. This morning a detective called me asking if i knew anything else and referred to it as a homicide investigation. Sorry for the long winded post but i had to tell someone Tldr: apparently my new neighbor fucked someone else's wife and got beat to death for it.
