During their marriage, Kim became sexually involved with the Dorseys' friend Lance Kirkpatrick. In October 2012, while Derrick was out of town, Kirkpatrick went to the Dorsey home where he and Kim had an argument. According to Kirkpatrick, there was a struggle and Kim fired a gun at him. He said he “was fighting for his own life and was scared.” Kim Dorsey was beaten with a pool stick and stabbed in the throat with a kitchen knife. When Derrick Dorsey returned home the next day, he discovered his wife’s beaten dead body in their bedroom.
