Reyna was arrested in September for calling in threats at River Oaks, St. Fredrick, and Ouachita Christian School.
Reyna is out of jail on a $200,000 bond.
The trial of a former River Oaks School teacher accused of calling in bomb threats to three schools is scheduled to begin Monday.
Reyna is accused of calling in bomb threats at River Oaks, St. Fredrick, and Ouachita Christian School.
During a court hearing in October, Ouachita Parish Sheriff's Senior Investigator John Spires took the stand and discussed details of the investigation into Reyna.
Spires said after finding Reyna's phone in a dumpster old Old Sterlington Road investigators searched the phone's record which later lead them to identifying the phone as David Reyna's.
Sheriff Jay Russell, Chief Deputy Marc Mashaw, Major Jason Pleasant and Spires all went to Reyna's house where Spires said he first denied making the 911 calls but later admitted to making the calls. Spires said when they asked Reyna why he made the calls he said he didn't know.
In court documents Reyna said he used illegal drugs, suffers from emotional issues such as depression, does not sleep, and is having martial trouble and difficulty with his newborn child.
His bond is set for $200,000.
