PAW PAW, Mich. (WOOD) - A Van Buren County man filed to divorce his wife a week after authorities say he killed her.

Brent Bogseth filed to divorce his wife, Kimberly, on Sept. 8. He's accused of murdering her seven days earlier on Sept. 1.

Brent Bogseth said in the divorce documents that his wife had cheated on him. The documents allege he confronted the man with whom his wife was having an affair and that man admitted to it, apologized and then told Kimberly Bogseth he would "no longer see her."

The documents state that Kimberly Bogseth "left the marital home in a huff" and that even though Brent Bogseth had tried to find her, he was unsuccessful.

The divorce petition also alleges Kimberly Bogseth had other extramarital affairs and that she "abandoned" the couple's young son and left the state. Brent Bogseth asked the court to grant him custody of the boy.

24 Hour News 8 was told that neighbors found Kimberly Bogseth's body on Sept. 9 near the Bogseths' Columbia Township home in Van Buren County.

After his wife's remains were discovered, Brent Bogseth left Michigan and headed to Chicago where the couple used to live.

The Van Buren County Sheriff's Office issued a warrant for his arrest and he was picked up by the Chicago Police Department. He saw a Cook County judge Friday morning to discuss extradition back to Michigan where he'll face open murder charges.
