My brother and cousin fight with a knife

Date: 9/13/2020

I was in a house with my family and my family let my cousin, Vince, in with us. People were chasing him so we had to be careful but he was good with a knife so I eased me for a while. Groups of people kept targeting our family mainly because of my cousin. My brother took out a small knife then a giant kitchen knife on my cousin and in response he billed out an average knife and they started attacking each other. Later I see my brother with some red strips on his arms.
