ITHACA, N.Y. (WENY) -- The former Cornell University student accused of having bomb-making materials and other weapons will undergo a pretrial mental health evaluation. 

20-year-old Maximilien Reynolds is charged with possession of a destructive device and silencers, as well as aiding and abetting the straw purchase of a rifle. 

The latter charge means that a person who is prohibited from buying a gun used another person to buy one on their behalf.

Reynolds is on leave from Cornell University, where he studied plant science, according to his Facebook page.

According to federal records, authorities found an unassembled Savage MSR-15 Patrol rifle and a homemade silencer in his apartment, according to federal records.

Police also found fireworks that had been modified to add shotgun pellets to them, a gas mask, body armor, chemicals frequently used in homemade explosives, ball bearings that could be used as shrapnel in a bomb and pipes commonly used to assemble destructive devices.

According to the US District Court in Syracuse, Reynolds has 45 days to be examined. 

The evaluation will determine if he was insane at the time of the crime and whether or not an insanity plea will hold up in court.
