(Knoxville, Iowa) -- A Pella woman accused of murder is admitting to stabbing her estranged husband's girlfriend.
Michelle Boat took the stand in court today, as she faces first-degree murder charges in the 2019 stabbing of Tracy Mondabaugh. Boat admitted to the stabbing, but said it happened in the heat of the moment.
Boat said she had followed Mondabaugh to find out where her husband, Nick Boat, was staying and planned to beg him to come home.
The prosecution asked her about previous threats she'd made against Mondabaugh, which she said were to scare Mondabaugh away from her husband.
The prosecution is arguing the murder was pre-meditated. The defense is arguing that Boat was not in her right mind at the time of the stabbing.
Closing arguments in the trial begin Tuesday.
