A Far North Peoria man accused of killing his wife on Valentine’s Day was apparently involved with a young Lithuanian woman in the United States for school.

Peoria County State’s Attorney Jerry Brady stopped short of saying Thursday the relationship was a motive for the death of 39-year-old Denise Leuthold, but it was clear from a 20-minute question-and-answer session with a Peoria police detective during Nathan Leuthold’s bond hearing that police believe there is some significance.

New details came out during the hearing in Peoria County Circuit Court where Nathan Leuthold, 37, whose address is listed as 700 W. Mossville Road, the home of his in-laws, was charged with first-degree murder in connection with the Feb. 14 death of his wife, Denise. He faces 20 to 60 years in prison if convicted.

One new revelation was a note police found a day after the slaying. The note, which is believed to be in Denise Leuthold’s handwriting, was found in a day planner and indicates she believed her husband wanted her dead and that he was making her look bad by running around with a 20-year-old woman.

The woman, named Aina, who is attending a Christian college in Chicago, initially told police her relationship with Nathan Leuthold was strictly professional. She later admitted the man came to Chicago and the two got a hotel room “less than 20 times.” Aina denied there was a physical relationship, the detective said, but also admitted Nathan Leuthold shared a bank account with her, bought clothing for her and largely funded her living expenses.

Peoria police Detective Jason Leigh also told Judge Richard McCoy they learned the woman was previously dismissed from a similar college in Pensacola, Fla., for having an inappropriate relationship with Nathan Leuthold.

McCoy set bond at $2 million and ordered Nathan Leuthold to hand over his passport as Brady maintained the missionary who has gone overseas several times was a flight risk.

Nathan Leuthold, seen over a video-conferencing monitor wearing a Peoria County Jail jumpsuit, said little during the hearing. His attorney, Thomas Penn Jr., has indicated in the past he wouldn’t comment on the case.

As Nathan Leuthold listened, a Peoria police detective gave a summary of what he and fellow officers had learned. That’s highly unusual as prosecutors, not police, usually give such a statement during a bond hearing.

Responding to Brady’s questions, Leigh told McCoy that Denise Leuthold died from a single gunshot wound to the head and was found inside the home, but there were no signs of forced entry.

Also, the detective said a neighbor had seen Nathan Leuthold about 12:20 p.m. the day his wife was killed, walking on Mossville Road toward the house and away from a parking lot where police later found a car the couple used.

That was important, as Nathan Leuthold had told police the night of the shooting that he left the home about 11:15 or 11:30 a.m. and didn’t return again until about 3 p.m. when he found a door ajar.

Leigh said the neighbor, who didn’t know who Nathan Leuthold was, then called police a few days later to say she saw the man who was walking on Mossville Road driving a grey SUV near the family’s home. The man scared her because, at the time, many in the neighborhood, which has few violent crimes, were on edge because of the apparent break-in and slaying.

Another neighbor reported to police hearing a gunshot sometime between 12:30 and 12:45 p.m. Feb. 14, the detective said, which gives a rough time frame as to when things happened.

Nathan Leuthold, a Baptist missionary who went often to Lithuania for his work, called police about 3:15 p.m. after picking up his youngest child to report a break-in. Police arrived and found his wife just inside the front door.

Initially, police investigated the case as a break-in gone bad and asked Nathan Leuthold what he thought would be missing. He told them two rings, a laptop computer and a digital camera, all which were later found missing and none of which have been recovered, Brady said after the hearing.

Also missing were his two firearms, a .40-caliber Glock and a .22-caliber handgun. Nathan Leuthold said the Glock was locked up in a gun case but the gun and the case were missing. Police found on a computer — it wasn’t said where or whose computer — information about how to silence a .40-caliber Glock and how to kill someone with insulin or by electrocuting them in the bathtub.

A grand jury likely will hear the case before the April 4 preliminary hearing. It wasn’t known if Peoria County prosecutors would seek to terminate Nathan Leuthold’s parental rights to the couple’s three children, a common practice when there is a familial homicide. Such a proceeding would occur in juvenile court and be off limits to the general public.
