Teresa Mikesell Miller was 51 when she was found dead in her Knoxville, Iowa, home on January 7, 2011, the victim of a fatal gunshot wound. Investigators concluded her death was not accidental and soon centered on people close to her.

Authorities alleged Teresa’s husband, Michael Jamey Miller, conspired with a colleague, Terry Tobias Cobbins Jr., because Michael was having an extramarital affair and feared the financial consequences of a divorce. Prosecutors say Michael offered to pay Cobbins to kill his wife, arranged a rental car for Cobbins on the day of the killing, and both men were arrested and charged with first-degree murder after Teresa’s body was discovered.

What details about Teresa’s life or the people around her might help explain how this plot unfolded, and does anyone have information about the case or the victims?
