Dolla, whose real name is Roderick Anthony Burton II, was gunned down while he and rapper D.J. Shabbazz waited in the valet area of the parking structure of the mall where the hip-hop artists had been shopping, Burton's publicist Sue Vannasing told the Times.
Police told the newspaper two suspects fled the scene and a "person of interest" was later detained as he attempted to board a flight out of Los Angeles International Airport.
