Allah and Salah Salahadyn are charged with felony robbery in the case. Salahadyn pleaded not guilty last month.
Prosecutors in Allah's case handed over about 20 CDs worth of evidence Wednesday. Allah's public defender, Paul Ksicinski, says he can't comment until he's had a chance to look through all the material.
A criminal complaint says Allah provided the stun gun used to attack and rob a violin concertmaster. The complaint says Salahadyn had been plotting to steal a Stradivarius.
Police recovered the 300-year-old violin in good condition.
