Prosecutors in Phil Spector's murder case have asked a judge to allow testimony from a former assistant who says the famous pop music producer twice pointed a gun at her head.

Devra Robitaille, who worked at Warner Spector Records from 1974 to 1977, alleges he placed a shotgun or rifle against her head when she attempted to leave a party at his Los Angeles home. She claims a similar incident took place a decade later.

In court documents filed April 3, Deputy District Attorney Alan Jackson said the testimony demonstrates Spector's "long history of gun-related violence directed at women." Phil Spector's attorney did not immediately comment.

Spector, whose age has been given as 66 or 67, faces life in prison if convicted of fatally shooting actress Lana Clarkson at his home in February, 2003. He has pleaded not guilty, claiming she committed suicide.

An April 10 hearing was scheduled to consider the prosecution's request. Prosecutors plan to present testimony from four other women who claim Spector threatened them with a gun.
