LAS VEGAS (AP) — A man who prosecutors say orchestrated the 1996 drive-by shooting of rapper Tupac Shakur was arrested and charged with murder Friday in a long-awaited breakthrough in one of hip-hop’s most enduring mysteries.

Duane “Keffe D” Davis, 60, has long been known to investigators as one of four suspects identified early in the investigation. He isn’t the accused gunman but was described as the “shot caller” by authorities Friday at a news conference and in court.

Davis himself admitted in interviews and in his 2019 tell-all memoir, “Compton Street Legend,” that he provided the gun used in the drive-by shooting.

Davis was arrested early Friday while on a walk near his home on the outskirts of Las Vegas, hours before prosecutors announced in court that a Nevada grand jury had indicted the self-described “gangster” on one count of murder with a deadly weapon.

The grand jury also voted to add a sentencing enhancement to the murder charge for gang activity that if he’s convicted, could add up to 20 additional years.

The first-ever arrest in the case came more than two months after Las Vegas police raided Davis’ home in the nearby city of Henderson for items they described at the time as “concerning the murder of Tupac Shakur.”
