Prosecutors say the dispute over $20 led Chiselom to take a duffel bag belonging to Law's girlfriend as he left the apartment.
Law then followed and kicked Chiselom down a stairway outside the apartment.
Prosecutors say Law then stabbed Chiselom at the bottom of the stairs. A defense attorney argued Chiselom ran back up the stairs attacking Law, who reacted in self defense.
The jury decided against the more serious charge of voluntary manslaughter.
