The Supreme Court of Missouri last week finalized the execution date for a 45-year-old man sentenced to death for sexually assaulting and murdering a 6-year-old girl in 2002 by bashing her head in with a brick.

In a “per curiam” order from all seven justices, the court declared that Johnny A. Johnson will be put to death on Aug.1, 2023 for the horrific death of young Cassandra “Casey” Williamson. The court’s order came after the state filed a motion in November 2022 seeking to have Johnson’s death formally placed on the calendar after his numerous appeal attempts failed.

A jury in 2005 convicted Johnson on charges of first-degree murder, armed criminal action, kidnapping, and attempted forcible rape. Jurors recommended a sentence of death on the murder charge and life without parole on the remaining charges, which the presiding judge accepted.

According to court documents, Casey lived with her mom and siblings at her grandfather’s house on Benton Street in Valley Park, about 20 miles west of St. Louis. Her father was staying across the street with another couple so he could remain close to his children. That couple also allowed Johnson, then 24, to stay at the house for a few nights.

On the night of July 25, 2002, Casey also stayed at the residence so she could be with her father.

On the morning of July 26, 2002, Johnson woke up on the living room couch with Casey standing in the room watching television. Johnson then decided “this was his best opportunity to have sex with her,” former Justice William Ray Price, Jr. wrote in a 2006 ruling in the case.
