Cleveland, OH – Roger L. Pryatel avoided prison time but received a probationary sentence in 1999 after attempting to illegally dump hazardous waste into Lake Erie and then escalating into threats against a potential witness. The case, investigated by the Environmental Protection Agency (EPA) and prosecuted as a criminal matter, highlights the lengths to which some individuals will go to conceal environmental crimes—and the serious consequences of witness intimidation.
According to court documents, Pryatel solicited the aid of an acquaintance in May 1998, requesting the use of the man’s boat to transport and dispose of eight drums of unidentified hazardous waste directly into Lake Erie. The acquaintance, described as an environmentalist, immediately refused to participate in the illegal dumping scheme and promptly alerted authorities to Pryatel’s intentions. This act of responsible citizenship would then subject him – and his girlfriend – to a campaign of harassment and escalating threats.
Rather than abandoning his scheme, Pryatel allegedly began a pattern of intimidation directed at the acquaintance who reported him. Investigators state Pryatel repeatedly threatened both the man and his girlfriend with bodily harm, including death, in an attempt to silence them and prevent their cooperation with the ongoing investigation. This behavior quickly transitioned the case from an environmental violation to a serious federal crime involving obstruction of justice and witness tampering.
Legal Ramifications
Pryatel was indicted on four counts of retaliating against a witness, victim, or informant on May 6, 1998, specifically violating 18 U.S.C. 1513, a statute designed to protect individuals involved in federal investigations. He later pleaded guilty to two counts of the indictment on November 10, 1998. The prosecution successfully argued that Pryatel’s actions weren’t simply harassment, but a deliberate attempt to obstruct a federal investigation and silence those who might testify against him.
Sentencing and Penalties
On March 22, 1999, Pryatel received a sentence of 36 months probation, with the first six months to be served under home detention. He was ordered to cover the costs associated with his home confinement, totaling approximately $819, and pay a $200 special assessment fee. While the sentence was less severe than imprisonment, it underscores the seriousness with which federal authorities treat threats against witnesses and those who report environmental crimes. Had Pryatel been convicted on all four original counts, he faced significantly harsher penalties, including potential imprisonment.
