Diamond, who found that Spisak also had "inappropriate sexual contact" with two other male inmates, said the former corrections officer's conduct was "appalling." The sentence was twice what the high end of the sentencing guidelines recommended.
Spisak pleaded guilty in March to one count of engaging in a sexual act with a ward.
J.W. testified that after he had been transferred to the FDC in 2009, Spisak saw him every day the corrections officer worked and repeatedly "made advances" on him and threatened him if he didn't cooperate with Spisak's sexual demands.
On Jan. 5, 2010, J.W. said, Spisak took him into his office and said he would set off his body alarm and tell authorities J.W. tried to assault him unless he performed oral sex.
According to court testimony, J.W. spit onto his own T-shirt after Spisak ejaculated, then covered it with his overalls. DNA tests subsequently matched the stained shirt to Spisak.
Inmates identified as J.M. and M.C.J. said Spisak granted them special jobs within the prison. Assistant U.S. Attorney Michelle Rotella said it was part of a pattern of "calculated, premeditated" conduct by Spisak in order to have more direct, frequent and close contact with his victim inmates. (Spisak was not criminally charged regarding his alleged acts with J.M. and M.C.J.)
J.M. testified he was subjected to twice-daily strip searches for more than a month in a maintenance closet and that Spisak touched his genitals and plied him with food, cigarettes and even "antidepressant pills" to ensure his cooperation.
When victim J.M. objected to Spisak's touching, Spisak allegedly taunted him, asking, "Who's going to believe you?"
Spisak, who worked at the FDC for nine years, resigned after investigators tried to question him about his assault of J.W.
