Lynda Lyon Block

Sibley filed a hand-written petition asking the Alabama Supreme Court to block his execution, claiming that Block had fired the shot that killed Motley. He was executed on August 4, 2005, by lethal injection.

Block was executed on May 10, 2002. Her execution occurred at the Holman Correctional Facility near Atmore, Alabama.

Block, Alabama Institutional Serial #Z575, entered death row on December 21, 1994. While on death row, she was held at the Julia Tutwiler Prison for Women in Wetumpka, Alabama.

On October 4, 1993, Block's common-law husband, George Sibley, and Block's nine-year-old son were in a parked car in the parking lot of a Walmart store in Opelika, Alabama. A passer-by expressed concern for Block's son to Opelika Police Sergeant Roger Motley, saying it appeared to her as if the boy wanted help. She also believed the family could be living in the vehicle. At that time, Sibley and Block were on the run from the law in Florida after failing to appear for sentencing on an assault charge against Block's ex-husband. Motley found Sibley's car, parked behind and approached it, and asked for Sibley's license.

Before the execution, three friends visited Block for several hours. Block also saw a spiritual adviser. She had not requested a last meal, nor did she make a final statement. At approximately 12:00 midnight, she was placed in the electric chair and at 12:01 a.m., the current was turned on. At 12:10 a.m., she was pronounced dead. She was the last person to be electrocuted in Alabama and the first woman executed in the state since Rhonda Belle Martin in 1957.

Lynda Cheryle Lyon Block (February 8, 1948 – May 10, 2002) was an American convicted murderer.

Lynda Cheryle Lyon was born February 8, 1948, in Orlando, Florida, to Francis (Frank) Stephen Lyon and Berylene Elisabeth Owen. Lynda, and her sister Denyce (born 1952), lost their father when she was 10, when he died of heart failure. Lynda and her mother were never close, and Block claimed that her mother was both physically and mentally abusive.

Her second husband, George Sibley (September 8, 1942 – August 4, 2005), claimed that a constant trait of Block was charity. While living in Key West she served as Secretary of the Humane Society, and also as animal abuse investigator. She was also active in civic work besides her service to the Humane Society: for two years she served as president of the Friends of the Library in Key West and served as publicity director for a mayoral candidate.
