Allen Roberts, author of "Salamander," will discuss the Mark Hofmann forgeries and bombings on Sunday, Feb. 5, from 8 to 10 p.m. on KTKK Radio 630AM's weekly "Religion on the Line" show. Listeners will be invited to call in with comments regarding the Hofmann murders, which occurred in 1985 as a cover for Hofmann's business of forging historical documents, including many concerning the history of the LDS Church.
