Winneconne man sentenced to 8 months in jail on federal ammunition charge
GREEN BAY – The drunken and angry wrath of a Winneconne man at an ex-girlfriend, which has led to charges of cyberstalking and possession of ammunition as a criminal, was sentenced to eight months in jail this week by a federal court for the ammunition offense.
In October, Jon E. Janikowski, 37, learned that an uncle had died of COVID-19 and he contacted a former girlfriend with whom he had a long-term but “toxic” relationship, his lawyer wrote at court.
The two went to a bar, drank, used drugs and prescription drugs. The next morning, they were back angry with each other and causing arguments.
Janikowski left and, while still under the influence, tried to phone the woman, but she did not answer his calls. Hurt and enraged, Janikowski used Facebook Messenger to leave angry and obscene comments.

Oshkosh Police were contacted and found Janikowski in his truck. They eventually convinced him to get out of the vehicle and after that he threw a knife into the bed of the truck. Several knives, drug paraphernalia and a briefcase containing a shotgun and rifle cartridges were found in the cab of the truck, police said.
At the time, Janikowski was under extended surveillance following a domestic violence conviction in Waushara County. His arrest, alcohol consumption, and contact with the ex-girlfriend violated his conditions of supervision. In March, his surveillance was revoked and he was sentenced to 3.5 years in prison.
Janikowski pleaded guilty to the ammunition charge in April and on Monday his lawyer Krista Halla-Valdes requested a six-month sentence concurrent with the length of his state sentence.
Halla-Valdes also told District Judge William Griesbach that Janikowski suffered a head injury while in the military in Iraq and is considered 100% disabled. He also suffers from post-traumatic stress disorder, which he sometimes self-treats with drugs and alcohol.
Assistant U.S. Attorney Daniel Humble said Janikowski’s possession of ammunition remains a serious matter given her criminal history, anger and mental health issues and requiring a handgun from the woman.
Griesbach imposed a sentence below the advisory guideline range and allowed Janikowski to serve it at the same time as his current sentence, as they both involved the same conduct.
