PEORIA, Ill. -- In his first court appearance, state prosecutors revealed Nathan Leuthold had a complex relationship with a young Lithuanian woman and his wife knew about it.
Leuthold is charged with one count of first degree murder for the shooting death of his wife, Denise, who was found dead in her parents' home on Mossville Road.
Many details about the Valentine's Day murder emerged during Thursday's 20 minute hearing, including an apparent love triangle although the other woman involved denied a sexual relationship with Leuthold.
Police also revealed they found a note, which is believed to be in Denise Leuthold’s handwriting, in a day planner. It says she believed her husband wanted her dead and that he was making her look bad by running around with a 20-year-old woman.
"There is a Lithuanian woman involved, yes," said Peoria County State's Attorney Jerry Brady.
Brady confirms to News 25 that the woman, Aina Dobilaite, is a 20-year-old Lithuanian student the Leuthold's brought to the states to attend school.
Police detective Jason Leigh says she moved to Chicago after she was kicked out of a Florida Christian College for an inappropriate relationship with Nathan Leuthold. She told police he has stayed in a luxury hotel suite with her less than 20 times since August. The two also share a bank account and he supports 90 percent of her finances.
Brady says he has not heard that Leuthold had any other source of income, outside of his missionary work.
Brady described Leuthold's murder as an execution, as she was shot in the head with a .40 caliber Glock, a gun police say Leuthold owned. Detectives say Leuthold told police he was not home from 11:15 a.m. until 3 p.m., when he reported the burglary. Yet, one neighbor told police she saw him walking on Mossville around 12:20 and another says she heard a gun shot 15 minutes later.
Brady says the burglary was staged. Police also found evidence on Nathan's computer that he had searched for the best way to kill someone, including how to muzzle a gunshot.
"All cases are difficult, this case has a lot of circumstantial evidence," said Brady. "It also has a lot of hard evidence."
Brady wanted a $4 million dollar bond, but after Leuthold agreed to give up his passport, bond was set at $2 million.
"I know he has funds available to him, I know he was employed. Whether he has enough to make that amount of bond, I don't know," said Brady.
He faces 20 to 60 years in prison if convicted.
