Roderick Anthony Burton II, otherwise known as the rapper Dolla, was murdered yesterday at the Beverly Center shopping mall in Los Angeles. The Atlanta-based rapper was standing near the mall’s valet parking area when he was shot in the head. The suspect then fled in a silver Merecedes SUV, and a 20-year-old “person of interest” was apprehended about an hour later at LAX. Police have not yet announced a motive. Considered up-and-coming, Dolla’s first album was scheduled for release this summer. His first single, “Who the … Is That?”, was released in 2007.
