RIP-Robert Culp

Robert Culp, the actor who teamed with Bill Cosby in the racially groundbreaking TV series "I Spy" and was Bob in the critically acclaimed sex comedy "Bob & Carol & Ted & Alice," died Wednesday after collapsing outside his Hollywood home, his agent said. Culp was 79.

His manager, Hillard Elkins, said the actor was on a walk when he fell. He was taken to a hospital and pronounced dead just before noon. The actor's son was told he died of a heart attack, Elkins said, though police were unsure if the fall was medically related.

Los Angeles police Lt. Robert Binder said no foul play was suspected. Binder said a jogger found Culp, who apparently fell and struck his head
