Phil Spector's blood was not found on the gun used to kill the actress he is accused of murdering, a court has heard.

Forensic expert Steve Renteria testified only Lana Clarkson's DNA was discovered on the .38-caliber revolver found at her feet at the music producer's Los Angeles mansion on February 3, 2003. A large smear of blood on a staircase banister next to where Clarkson's body was found slumped in a chair also only showed her DNA.
