Law enforcement authorities now say the shooting of a Kansas man by his wife was not an accident.

A 31-year-old Potwin woman was arrested Monday morning in her husband’s shooting at their home Sunday.

Butler County authorities originally believed the shooting was an accident, after the couple both said it was in separate statements.

Sheriff Kelly Herzet says investigators decided the shooting wasn’t accidental after interviewing the couple’s four children. He says the children told investigators the couple was arguing when the woman shot her husband.

The woman is being held in the county jail pending filing of formal charges.

The children were placed with a grandparent.

The 44-year-old husband remains in critical condition at a Wichita hospital.
