"I am convinced that the thorough and accurate investigation of the evidence by the Los Angeles sheriff's department, its criminalists and the county coroner will prove that Phil Spector is innocent of any crime," attorney Robert Shapiro told The Associated Press, speaking publicly about the case for the first time since his client's Feb. 3 arrest.

Spector, 62, was arrested for investigation of murder and released after posting $1 million bail. He has not been charged, and authorities say they are investigating.

Shapiro was responding to a Los Angeles County Sheriff's Department statement issued earlier Tuesday that said investigators had discounted suicide as a possible cause of Clarkson's death.
