GRAND RAPIDS, MI -- Jeffery Klein, the 625-pound man who claimed his weight prevented him from making court dates for more than two years, has been sentenced to a minimum 18 months in prison on a bomb threat charge.

Klein, 44, was sentenced to 18 months to four years in prison Friday, Jan. 23, in Kent County Circuit Court.

Klein pleaded with Judge Dennis Leiber to allow let him go free with time served and probation.

But Leiber wasn't moved by the plea.

"All of this was done because of your sadistic desire for revenge," Leiber said.

Klein has been in jail since Jan. 1 when he was arrested by Grand Rapids police for driving on a suspended license.

Prior to his arrest, he had complained that health issues related to his weight made him bed-bound and confined him to his home.

Klein pleaded guilty to making a bomb threat.

At that time, in August 2012, he lived at the Cedar Springs Mobile Estates and apparently was in a dispute with the park managers.

In court Friday, Klein's family cried as they heard the judge deliver the sentence.

They said they are worried about his health and how he will cope in prison.
