The trial of Duane "Keffe D" Davis, the only suspect ever charged in the 1996 murder of rap superstar Tupac Shakur, commenced Monday in Las Vegas. Davis, 63, a former gang boss, has pleaded not guilty to charges of murder with a deadly weapon with the intent to promote, further or assist a criminal gang.

Shakur was killed in a drive-by shooting on September 7, 1996. The details surrounding the event and Davis's alleged involvement have been the subject of intense public and legal scrutiny for decades. This trial marks a significant development in a case that has remained unsolved for nearly three decades, bringing the focus of the justice system to the suspect's alleged role in the rapper's death.
