Steve Tucker ended a ten-year federal prison sentence last year. He served his time for selling light bulbs--specifically grow lights--that, while themselves legal, were sold to some customers that were using them to grow marijuana. Even though he and his brother asked any customers who so much as mentioned marijuana to leave and refused to sell any products which had any visible references to marijuana, they were successfully prosecuted on conspiracy charges because they had knowledge that some of their customers were using their products to grow marijuana.
His brother Gary, who was given a fifteen-year sentence that was reduced to ten after a successful petition to apply a change in policy from the U.S. Sentencing Commission, died of cancer at about the time his sentence was served.
