It was a fascinating day in court as day two of testimony continued in the murder trial against Duane Davis, the former gang leader who prosecutors say orchestrated the murder of rapper Tupac Shakur 30 years ago.

Meantime, the medical examiner showed jurors and the courtroom never before seen autopsy photos of Shakur, prompting several family members to leave the courtroom.
