Ann Marie Harrison (February 22, 1974 – March 22, 1989) was a 15-year-old American girl who was kidnapped, raped, and murdered by two men in Raytown, Missouri.

[1][2] Her two killers: Michael Anthony Taylor (January 30, 1967 – February 26, 2014) and Roderick Nunley (March 10, 1965 – September 1, 2015) were executed for the crime by the state of Missouri via lethal injection, in 2014 and 2015, respectively.

Figuring her daughter was still inside the house, she instructed the bus driver to move on, saying she would drive her to school.

As Harrison pleaded with them to let her live, both men stabbed her to death with kitchen knives as she lay in the trunk of the car.

[7] Thirty-six hours after Harrison's abduction, a neighbor reported the abandoned blue '84 Monte Carlo.

After calling the owner to collect it, he arrived and opened the trunk, discovering Harrison's body.

[8] Three months after Harrison's murder, the reward for information leading to the capture of her killers had reached $9,000.

[10] In 1993, the Supreme Court of Missouri overturned the death sentences for Nunley and Taylor without commenting or providing a reason for doing so.

[12] Taylor was first scheduled to be executed on February 1, 2006, but was granted a stay by the United States Court of Appeals for the Eighth Circuit, on the grounds that lethal injection in his case could be cruel and unusual punishment.

Justice Samuel Alito, in his first official act on the Supreme Court, voted with the majority (6–3) to refuse Missouri's request.

The appeals pending before the Court questioned the constitutionality of the death penalty, the sentencing of Nunley before a jury rather than a judge, and the secrecy of the state of Missouri in acquiring the drug used to perform the execution.
