More information came out during the trial, including that Calderon and her co-worker friend, Robert Harden, had met up in the early afternoon for a drink and then visited the Grove before finding themselves in Hollywood that Tuesday evening. Harden also did not notice Calderon had been stabbed until after they left the scene. Police were able to quickly find the suspects based on the photos Calderon and Harden had taken of them.
According to CBS, Kinnear had previously been arrested some 46 times, including seven times for assault with a deadly weapon. California doesn't consider that a violent crime, though, and Kinnear was apparently released early based on realignment.
