Former Atlanta lawyer Fred Tokars, who arranged the murder of his wife in 1992, has died in federal prison, his longtime defense attorney confirmed Wednesday.

Jerry Froelich said Tokars’ brother was notified of his death by a prison chaplain last weekend. Froelich said he has not been told of the precise cause of death, although he said Tokars had a form of multiple sclerosis that had left him unable to walk for the past decade.
