Robert Durst denies killing his friend in murder trial testimony

Robert Durst took the stand at his California murder trial Monday and immediately denied killing his best friend, who prosecutors say was about to reveal to investigators his involvement in the 1982 disappearance of his wife.

"Bob, did you kill Susan Berman?" Durst's attorney Dick DeGuerin said to open the testimony of the 78-year-old New York real estate heir. "No," Durst answered.
