A fifth woman testified yesterday that music producer Phil Spector, accused of having murdered actress Lana Clarkson, threatened her at gunpoint.

Devra Robitaiile told jurors yesterday about her romantic relationship with Phil Spector and how he threatened her at gunpoint twice. Robitaiile worked for Spector for several years at Warner Spector Records.

She told how she had been at a party held in Spector’s house in the late 1970s. When she wanted to leave, the music producer, who had consumed alcohol, locked the door and threatened her with a gun. He eventually allowed her to leave. No one was injured.

Four other women have already spoken of similar experiences with Spector, which the prosecution claims to be a pattern: he drinks and threatens women when they reject him sexually.

Actress Lana Clarkson was found dead, shot in the mouth, in his home, in February 2003. The two had met that night at House of Blues on the Sunset Strip, where Clarkson worked as a hostess. He invited her to his home, “just for a drink.”

The defense claims that Lana Clarkson accidentally shot herself, as she was depressed at the time due to her failed career as an actress and financial woes. Spector has maintained to this day that he is innocent.

Also on Tuesday, the 67-year-old Phil Spector formally waived his right to testify on his own trial. His lawyers then told Los Angeles Superior Court Judge Larry Paul Fidler they would conditionally rest their case.

The judge told the jury testimony would probably end this week.

Spector has been free on $1 million bail ever since his arrest. If he is convicted, he faces between 15 years and life in prison.

The music producer is famed for having created the “Wall of Sound” recording technique in the 1960s. He has worked with the Beatles, the Ronettes, Ike and Tina Turner and Sonny and Cher. He was inducted into the Rock and Roll Hall of Fame in 1989.
