MONROE — The boyfriend of a missing Monticello mother is scheduled for a jury trial Wednesday, April 13, on misdemeanor charges — even as the investigation in the disappearance of the 37-year-old woman continues.

While he has yet to be charged in the girlfriend’s case, Derek Hammer of Shannon, Ill., was arraigned on three disorderly conduct charges related to a domestic incident involving the woman, Melissa Trumpy, and her family in Monticello. 

District attorney Craig Nolen has asked the judge for a large pool of potential jurors in advance of the trial. The case has — and continues to be — the subject of numerous media reports and assertions by relatives who contend that Hammer was the last person to see Trumpy; and likely knows what happened to her.

The trial and jury selection is set for 8:30 a.m. Wednesday before judge Faun Marie Phillipson. Court records indicate Hammer is being represented by attorney Michael Shannon Murphy.
