The alleged ringleader of a foiled plot to massacre Somali Muslims in southwest Kansas is appealing his conviction and prison sentence.

The attorney representing Patrick Stein on Monday filed a notice of appeal to the 10th Circuit Court of Appeals.

Stein was among three militia members convicted of plotting in 2016 to blow up a mosque and apartments housing Somalis in Garden City.

A judge last month sentenced Stein to 30 years in prison for conspiracy to use a weapon of mass destruction and 10 years for conspiracy against civil rights. The sentences will run concurrently.

Stein will return to federal court on Feb. 22 for a change-of-plea hearing and sentencing in a separate indictment alleging possession of child pornography. The material was discovered during searches in the bomb case.
