Teresa Lewis became the first woman to be executed by the U.S. state of Virginia since 1912, and the first woman in the state to be executed by lethal injection.

Teresa Wilson Bean Lewis was an American murderer who was the only woman on death row in Virginia prior to her execution. She was sentenced to death by lethal injection for the murders of her husband and stepson in October 2002. Lewis sought to profit from a $250,000 life insurance policy her stepson had taken out as a U.S. Army reservist in anticipation of his deployment to Iraq.

Virginia, officially the Commonwealth of Virginia, is a state in the Southeastern and Mid-Atlantic regions of the United States between the Atlantic Coast and the Appalachian Mountains. The state's capital is Richmond and its most populous city is Virginia Beach. Its most populous subdivision is Fairfax County, part of Northern Virginia, where slightly over a third of Virginia's population of more than 8.8 million live.

Lethal injection is the practice of injecting one or more drugs into a person for the express purpose of causing death. The main application for this procedure is capital punishment, but the term may also be applied in a broader sense to include euthanasia and other forms of suicide. The drugs cause the person to become unconscious, stop their breathing, and cause a heart arrhythmia, in that order.
