The snub-nosed Colt Cobra revolver was not registered and never definitively linked to Spector, though prosecutors argued he used it to shoot Lana Clarkson in the mouth on February 3, 2003.

The defense argues Clarkson shot herself and is likely to suggest that the gun could have belonged to her.

She had accompanied Spector to his Alhambra mansion after meeting him at her job as a hostess at the House of Blues just hours before her death.

Detective Mark Lillienfeld also showed jurors photographs to point out a holster in an open drawer of a bureau near the spot where Clarkson's body was found slumped in a chair. The holster also fit the gun, Lillienfeld testified.

Lillienfeld also testified about Spector's small arsenal, including two fully loaded blue steel handguns, an unloaded 12-gauge pump shotgun and ammunition tucked away in his home. The dozens of rounds of ammunition were the same types found in the gun that killed Clarkson, he said.

Spector's briefcase was on a chair next to Clarkson's body, Lillienfeld said, adding it contained some over-the-counter medications and a tinfoil with one Viagra pill and empty spaces for two more.

The prosecution previously called several women from Spector's past to testify that he had threatened them with guns when they picked up their purses and tried to leave his presence.

Prosecutor Pat Dixon made extensive use of the bloody pictures of Clarkson's body and each time they were shown he signaled her mother and sister to look away.

Defense attorney Bradley Brunon, setting the stage for an effort to show evidence contamination and mishandling, showed the jurors photos of detectives and investigators surrounding Clarkson's body, most of them barehanded.

Lillienfeld said he and others did not wear gloves because they did not touch anything.

Spector, 67, rose to fame with the hit-making "Wall of Sound" recording technique in the 1960s.

Clarkson was best known for her role in the 1985 movie Barbarian Queen. ASSOCIATED PRESS
