The man arrested for a bank robbery last week in Minoa is a math teacher at Cicero-North Syracuse High School. Mark Gurniak, 28, of Minoa, taught 11th graders for six years.
According to C-NS Principal James Froio, the school was aware that Gurniak had previous trouble in regards to the law, but not to this degree.
In January, Gurniak was charged with criminal possession of stolen property in the town of Clay and will answer to those charges next week.
Superintendent Jerome Melvin also commented on an arrest last summer.
"To my understanding, the June 2008 arrest ended in an adjournment in contemplation of dismissal," Melvin said in an interview with News10Now Allison Lazarz. "So there was no decision as far as he was not found guilty."
Gurniak is accused of entering a Chase Bank in Minoa with a shotgun and demanding money. He was arrested May 17 after a joint investigation with the FBI, and is charged with first-degree robbery. He was jailed at the Onondaga County Justice Center on $150,000 cash bail.
"This was very disturbing and shocking to the students and to the teachers here," Froio said about the robbery.
Froio said he told Gurniak's students they were welcome to talk to counselors if needed. He said he didn't feel it was necessary to bring in additional counselors for school-wide sessions because Gurniak only had a class load of about 140 students.
