DULUTH -

The former owner of the Duluth head shop, Last Place on Earth, was dealt a huge blow Tuesday, October 11, after the U.S. Supreme Court refused to hear his appeal.

Owner, Jim Carlson was found guilty of selling synthetic drugs in 2013 and is serving a 17 and a half year prison sentence.

FOX 21 spoke with his attorney, Randall Tigue, today. He believes that his client wasn't given a fair shake, saying Carlson has a chance for clemency in the future, with the possibility of the lessening of sentences for non-violent offenders.

Lava Haugen, Carlson's former girlfriend, is currently serving a five-year sentence in connection with the crime.

His son, Joseph Gellerman, avoided prison and is serving probation.

Both of them were also seeking an appeal from the Supreme Court, which was denied.
