Miami, FL – A complex scheme to illegally divert and smuggle freon within the United States culminated in multiple convictions and sentences throughout 1995, with Adi Dara Dubash receiving a 22-month federal prison sentence. The case, investigated by the Environmental Protection Agency’s (EPA) Criminal Investigation Division, exposed a network of individuals exploiting loopholes in environmental regulations for financial gain.
The investigation began to unravel in early 1995, with Dubash initially indicted on January 5th, alongside several co-defendants. The core of the operation involved fraudulently documenting shipments of freon – a refrigerant regulated under the Clean Air Act – as exported, while in reality, the substance remained within U.S. borders. This allowed the defendants to bypass required EPA consumption allowances and avoid associated costs and regulations. Customs broker Tominelli played a crucial role in the scheme, facilitating the transportation of the freon and falsifying export paperwork.
However, Tominelli eventually became a cooperating witness, providing valuable information to investigators about the wider operation. This testimony proved pivotal in securing guilty pleas and convictions against multiple individuals. Patel entered a guilty plea on May 3rd, while Dubash followed suit on May 5th. Zborovsky and Prieto were also indicted, with Zborovsky pleading guilty on June 12th and Prieto being convicted after a trial that concluded the same day. Notably, charges against one individual were dropped after Zborovsky stated during debriefing that the defendant was unaware of the freon being smuggled.
The sentences handed down reflected the varying degrees of involvement in the conspiracy. Dubash, on July 24th, received 22 months of incarceration, a $200 special assessment, and a $6,000 fine. Patel received 36 months of probation for each count, to be served concurrently, alongside a $200 assessment. Zborovsky faced a combined sentence of four months incarceration, 36 months probation, and a $5,000 fine. Prieto received a more substantial 26-month prison sentence, also with 36 months of probation. Tominelli, as a cooperating witness, received 36 months probation and a $2,000 fine.
