Radice was last seen near his home in downtown Lancaster, California on May 15, 1995. He was visiting a neighbor in the vicinity of 10th Street West and Avenue J-4 at the time. He has never been heard from again.

Radice was born in New York, but he lived in the Lancaster area for most of his life and was well-known in the neighborhood. He fed the local birds and stray cats, sold jewelry door-to-door, and told stories, wrote poems and made posters concerning local history. He is a World War II veteran and was given awarded Silver Stars for distinguished service. He lived with his adult grandson at the time of his disappearance. His grandson did not report him missing; a friend did instead. Radice's grandson stated he was puzzled by his grandfather's disappearance but hadn't thought to go to the police.

Authorities believe Radice is missing under suspicious circumstances. His case remains unsolved.
