Dr. Randeep Mann's attorneys filed a motion asking federal prosecutors to file a bill of particulars detailing the charges against him. Mann is charged with using a weapon of mass destruction and attempting to destroy a vehicle in the explosion that hurt Dr. Trent Pierce.
U.S. District Judge Brian Miller had earlier granted prosecutors' request for Mann to say whether he intended to use an alibi defense. But the doctor's attorneys argue that the indictment never says whether Mann was the person who ignited the bomb at Pierce's home in West Memphis.
The defense argues that the indictment is unclear, which makes it difficult to determine whether an alibi defense would be appropriate.
