QUINCY -- A Liberty man was sentenced to 20 years in the Illinois Department of Corrections after an Adams County jury found him guilty of one count of home invasion with a dangerous weapon last year.
John A. Martineau faced up to 30 years in prison at Friday's sentencing in connection with the April 18, 2017, home invasion in Liberty.
Martineau, 53, was convicted Sept. 12 of entering the home of Ricky Liesen and threatening him with a knife. Prosecutors said Martineau rubbed the blade of the knife on Liesen's neck and face, leaving cuts. The jury found Martineau not guilty of one count of home invasion with a firearm.SClBMartineau was reportedly angered that Liesen had provided information on him to police officers in a different case.
Josh Jones, lead trial attorney for the states attorney's office, argued that Judge Amy Lannerd should sentence Martineau to 24 years in prison.
"(Liesen's) blood was on the knife," Jones said. "Mr. Martineau's fingerprints were on that knife. His DNA was on the knife."
Jones also blasted Martineau's claims in the pre-sentence investigation that he was acting in self-defense, noting he made no reference to defending himself in his interview with the Adams County Sheriff's Department.
"Now all of a sudden we hear, ‘I was in fear for my life," Jones said.
Martineau's attorney, Public Defender Babs Brennan, said Martineau told Lannerd that he was a combat medic in the Marines and after being honorably discharged, he worked in the medical field, eventually becoming a nurse.
She said he was diagnosed with post-traumatic stress disorder in 1995 and cognitive disorder in 2008, which prevented him from working.
Brennan called the incident "isolated" and asked that the minimum sentence of six years be imposed.
"He did not cause any major injuries before he stopped himself," she said.
In addressing the court, Martineau said he was remorseful for what happened, but claimed the actions were taken in self-defense. He said Liesen "flipped out" at him and reached for a kitchen drawer where there was a .45 calbier handgun Liesen said he had just gotten back from his stepson.
Martineau said he thought Liesen was going to shoot him, so he reached for his knife in self-defense.
"If I had to do it all over again, I wouldn't have gone over there," he said.
Martineau was given credit for 270 days served in the Adams County Jail. He will also be eligible for day-for-day credit for good behavior in prison.
