Jeffrey Willis, the man charged with kidnapping and killing Jessica Heeringa, made a court appearance Monday, Oct. 3.

Willis' attorney asked Judge Raymond Kostrzewa to step aside because he used to work in the Muskegon County prosecutor's office. The judge said he was not involved in the Heeringa investigation and refused to step aside.

The court schedule listed Willis as having a preliminary hearing Tuesday, but that has now been delayed until Tuesday, Oct. 25. Officials expect that'll be a full day of testimony detailing why Willis is charged with Heeringa's murder.

Willis, 46, was charged late last month in connection to the April 2013 kidnapping and murder of Heeringa.

“In my opinion, we found Jessica’s killer,” Muskegon County Prosecutor DJ Hilson said at a news conference announcing the charges in September.

He's also charged with the murder of 36-year-old Rebekah Bletsch, who was shot in the head during a jog in 2014.
