An arrest report obtained by the station detailed the altercation that led to the stabbing. 

A witness in the victim’s car told police that the fight began when a passenger in an SUV parked next to their car opened their door and dinged it. The victim, who has not been identified, got out to check the damage and was immediately confronted by the driver of the SUV, believed to be Marselles Brown. 

Brown allegedly confronted the man aggressively and the two engaged in a heated verbal altercation. The victim’s girlfriend said she witnessed her boyfriend slap the side mirror of the SUV.
