Legendary music producer Phil Spector's defense presented evidence on Tuesday to his murder retrial that they said proves his innocence in the 2003 shooting death of actress Lana Clarkson.

"Phillip Spector did not kill Lana Clarkson. That's what the evidence shows," lawyer Doron Weinberg told jurors as part of closing arguments to the 69-year-old music impresario's trial.

The prosecution, said Weinberg, "relies on the starting proposition that Phillip Spector is a bad person," and has focused on proving he killed Clarkson.

But "the forensic evidence shows that Phillip Spector is innocent," said Weinberg as he listed scientific clues he said bolstered arguments that Clarkson shot herself.

The B-movie actress died at age 40 of a gunshot wound at Spector's Alhambra mansion in eastern Los Angeles. The record producer has long been a suspect in her death but his attorneys say Clarkson committed suicide.

Spector has maintained Clarkson, best-known for her role in Roger Corman's 1985 cult classic 'The Barbarian Queen' but whose career had stalled at the time of her death, killed herself in the entrance hall to his mansion.

In closing statements on Monday, prosecutor Truc Do told jurors that Clarkson's shooting was "a death waiting to happen in (Spector's) world", following previous gun-related confrontations the producer had with five other women between 1975 and 1995.

"When he's ignited, he always does the same thing — he grabs a gun," Do said, noting incidents such as instigating alcohol-fueled games of Russian roulette with the women.

Prosecutors continue final statements on Wednesday before handing the responsibility for a verdict to the jury.

Spector's second trial began in October last year after a jury had been deadlocked 10 to two in the previous September 2007 trial, with the majority in favor of convicting Spector of second-degree murder.

Spector, still free six years after the alleged murder thanks to a million-dollar bail, is considered a rock-and-roll genius for having invented the "wall of sound" technique in the 1960s, which he used for artists like John Lennon, the Righteous Brothers and the Ronettes.
