SYCAMORE – A DeKalb County judge on Tuesday sentenced Michael G, Kulpin to 60 years in prison for the June 2016 murder of his girlfriend, 19-year-old Moorea Des Roches.
Kulpin, 22, was convicted in April of first-degree murder in the killing of Des Roches at the apartment the two were to share in the 900 block of Kimberly Drive. Prosecutors said Kulpin killed Des Roches on the day she moved in with the couple's infant son.
He beat Des Roches over the head with a frying pan until the handle broke, then repeatedly stabbed her while their infant son was in the next room, prosecutors said at Kulpin's April trial.
After killing Des Roches, he ditched his clothes and the knife in a dumpster outside the apartment. He took their son to a St. Charles motel before texting Des Roches’ parents the next day, pretending to be Moorea as he arranged dropping off the baby.
Then he went back to his apartment, wrapped Des Roches' body in a tablecloth, fitted sheet and shower curtain liner, and moved her from the bathroom to the adjacent bedroom. Police arrested him at the apartment around 10 p.m. on June 5, 2016, after finding Des Roches body.
There was a history of abuse in their relationship, and because Kulpin previously had been convicted of domestic battery against Des Roches, he faced between 20 and 100 years for her murder.
He also was sentenced to three years' imprisonment for concealing the murder.
Kulpin told police after his arrest that he was angry about social media postings he had seen and because Des Roches had not quickly responded to his text messages.
Kulpin had asked the Judge Robbin Stuckert to find him guilty of second-degree murder, arguing that it was a crime of passion.
