Two Witnesses Claim They Saw Tupac's Killers

March 3 [10:00 EST] -- Two members of Tupac Shakur's entourage told the "Los Angeles Times" that they informed police they saw who murdered the late rapper, but authorities have never asked them to review photos of suspects.

According to the "Times" report, the men (Malcolm Greenridge, one of Shakur's back-up performers, and Frank Alexander, Shakur's bodyguard) contend that they were driving in a car behind Shakur's when the rapper was fatally shot on September 7.

The men also reportedly claim that they told Las Vegas police that they witnessed the murder, but also told reporters that they were never contacted by police about the incident.

However, Las Vegas police told the "Times" the witnesses' stories were different on the night of Tupac's murder. Las Vegas Metro Police Sgt. Kevin Manning told the "Times," "Malcolm Greenridge and Frank Alexander gave us taped statements on the night of the shooting that are totally inconsistent with what they told the 'L.A. Times.' We would welcome their additional information and are surprised that they haven't contacted us sooner."

In light of the "Times" report, police have reportedly contacted one witness, and are planning to contact the other.

Greenridge and Alexander paint a clear picture of what they saw, and their information could certainly prove to be helpful for police.

"I saw four black males in a white Cadillac as it rolled by our car just before Tupac got shot," Greenridge told the "Times."

"I couldn't see which of those four people pulled the trigger, but I saw the gun come from the back seat out through the driver's front window, and I saw the driver. I did see all four faces for a few split seconds before the shooting though, and I told the police that. I can't promise you I could identify them, but nobody has ever even asked me to try."

Alexander reportedly said, "Could I identify the killer of my friend Tupac Shakur if the police showed me photos or a lineup of suspects? Possibly so. The thing is that the Las Vegas Metro Police never even tried to show me a photo of the shooter. Nor did they call me at any time for a lineup or to ask me anything concerning the shooting and death of Tupac."
