LINCOLN, Neb. (AP) — A man who spent 30 years on Nebraska’s death row for two cult murders died of complications from a rare cancer in his salivary glands.

As we reported earlier, Michael Ryan died May 24th at the Tecumseh State Correctional Institution. At the time, officials said Mr Ryan died of complications related to a brain tumor. But, a death certificate obtained by The Associated Press lists the cause of death for Michael Ryan as “metastatic carcinoma or parotid gland origin.”

Ryan was convicted in the 1985 torture and killing of 25-year-old James Thimm and in the beating death of five-year-old Luke Stice, at a farm near Rulo, Nebraska.

Ryan’s son was sentenced to life in prison for second-degree murder in Thimm’s death. Authorities said Dennis Ryan delivered the gunshot that killed Thimm after a month of torture. He was later released after winning a new trial and being convicted of a lesser charge.

Cult member Timothy Haverkamp was also convicted in the case.  Haverkamp was released after serving 23 years.
