Closing statements were scheduled Wednesday in federal court in Cleveland.
Prosecutors say the defendants planned or took part in at least one of five attacks last fall, cutting off Amish men's beards and women's hair because the hair carries spiritual significance in the faith. The suspects were charged with hate crimes because prosecutors believe religious differences between the Amish brought about the attacks.
None of the defense attorneys denied that hair-cuttings took place. Some said their clients participated, but they said what happened didn't amount to hate crimes.
Prosecutors wrapped up their case Tuesday, and defense attorneys didn't call witnesses.
The defendants are from the Bergholz settlement in eastern Ohio.
