Normally I post an obituary or a news article relating to a person's death, however for Camper none are available as far as I know. In fact, this is all that I have to go on:

Camper died December 7, 2010, however his death (at the age of 58) was not noticed until recently. He pitched for the Indians in 1977 and went 1-0 with a 3.86 ERA in three games. He collected his lone big league win in his very last big league game (and his only start), when he pitched 5 1/3 innings against the Blue Jays. He faced off against fellow rookie Jim Clancy and came out victorious. He pitched seven years in the minors, winning 59 games.
