An Adelaide drug dealer accused of murdering a man in his former high school's car park had no "murderous intent" and was just a "bully boy" wanting to send the victim a message, a Supreme Court trial has been told.
Kain Mazomenos, 26, Thomas Nicholls, 31, Thomas Pinnington, 25, and Jeremy Sandell, also 25, are standing trial for the murder of 24-year-old Victor Codea in an Adelaide High School car park in August 2020.
