Robert Luke, assigned prisoner number 1118AZ, arrived at Alcatraz Federal Penitentiary on April 14th 1954 and was paroled on April 29th 1959.

It was the smell of fresh mown grass wafting across the island from somewhere in San Francisco that spurred him to go the straight and narrow path.

Luke has been out of prison for 57 years, but it was only six years ago when he first confided to anyone other than his immediate family that he is an ex-con. Robert Luke authored a revealing book about his life on the Rock, Entombed on Alcatraz.

He now returns to Alcatraz Island on a regular basis where he has achieved “Rock” star status, regaling visitors from around the world about his recollections of his life at Alcatraz, and of course, autographing his top-selling book.

Join correspondent Tom Wilmer on Alcatraz Island for a conversation with Robert Luke and discover just how a whiff of fresh-cut grass transformed his life.

Alcatraz, administered by the National Park Service is a part of the Golden Gate National Recreation Area.
