It was this guilty verdict that that led Lammers' family to tears.
"You believe that the law is out there to help you and to help protect individuals," said Patricia Lammers, Blaec Lammers' mother. "I went to them thinking i could protect my son and help my son."
The decision came after witness testimony and evidence on Thursday and closing arguments on Friday.
There's no reason to purchase two guns when you're not familiar with guns and just want something to practice with," said Polk County Prosecutor Kenneth Ashlock.
"He didn't buy guns with the intent to do anything," said Donald Cooley, Lammers' attorney.
According to Lammers' mother's testimony, she notified police in November 2012 after she discovered her son-- who has a history of mental illness- had purchased guns.
"I went with the intention of letting them know he had purchased a weapon and I didn't want my son to kill himself," said Patricia Lammers.
The prosecution stressed the potential of Lammers to plot a mass shooting at a Walmart-- or possibly a local movie theater. Now, he may face up to 18 years in prison.
"My plan is to continue working with his mother and his father and developing some inroads into trying to get the mental health system to understand what kind of desperation position people like Blaec are in," Cooley said.
Prosector Kenneth Ashlock said the system worked and hopefully this would eliminate a threat to the area.
"I figured the judge would do the fair thing and do the legal thing," said Patricia Lammers. "My son did not commit a crime."
The sentencing is set for March 20. Lammers was denied bond and will remain at the Polk County Jail until his sentencing. Cooley said he plans to file an appeal.
