Teresa Post was still at the home when police arrived. She told police the victim was her husband and that she had stabbed him, according to the arrest affidavit.
Officers found a kitchen knife in the front yard near the suspect.
Post told police she and Perkins were arguing inside the house when he asked for a divorce. He walked outside, and she watched him through the window, according to the affidavit.
The 50-year-old said she saw Perkins leaning down by the tires of their vehicle, and she thought he was going to cut them.
Post went outside and pushed Perkins away from the car, at which point she allegedly saw a box cutter in his hand. When he stood up and turned around, she “stuck him one time with the kitchen knife,” according to information in the arrest affidavit.
David Perkins' death was ruled a criminal homicide by the medical examiner's office. Teresa Post was booked and charged with murder in his death.
