About John Thanos
Lived 1949 – 1994 (aged 45). John Thanos was a spree killer.
John Frederick Thanos (March 28, 1949 – May 17, 1994) was an American spree killer who was convicted in 1992 of the murders of three teenagers: Gregory Taylor, Billy Winebrenner, and Melody Pistorio. He was executed for the murders in 1994, becoming the first person to be executed in Maryland since 1961.
Early life Thanos was born in Dundalk, Maryland to John Steven and Patty Thanos. Steven was described as a mentally ill World War II veteran who severely abused John Thanos and even drugged his wife. Thanos was expelled from school and spent many years in and out of prison for various crimes he committed. He was charged for the offense and was sentenced to twenty-one years in prison. At his trial, he threatened the judge, and later attempted to break out of prison in 1971. He succeeded in escaping but was recaptured shortly afterwards and had eight years added to his sentence. Thanos was released from prison in April 1986. However, he returned only a month later after he committed an armed robbery at a convenience store. He was sentenced to a further eight years in prison. On April 15, 1990, Thanos was accidentally released early due to a mistake by a prison official who was later fired.
Upon his release, Thanos went to work as a bricklayer and then as a chicken processor in Salisbury. In the summer of 1990, he exposed himself to a woman who gave him a ride. The woman charged him for the offense and Thanos feared he would be returned to prison. Thanos would later reveal in a videotaped confession that he embarked on a crime spree because he was worried his parole was going to be revoked.
On August 31, Thanos encountered 18-year-old Greg Taylor while hitchhiking. Holding him at gunpoint while in his car, Thanos ordered Taylor to drive to a wooded area along a deserted logging road, where he intended to tie him to a tree. When Taylor refused to comply with his demands, Thanos laid Taylor down and murdered him by shooting him in the head three times. He then stole Taylor's car and altered his appearance to look more like him.
On September 1, Thanos arrived at a gas station and traded his father's watch to 16-year-old Billy Winebrenner for $20 and some gas. The two made a deal in which Thanos could return to the gas station and pay $60 to get the watch back. The following day, Thanos robbed a convenience store in Salisbury and shot the clerk in the head. The clerk survived the shooting and Thanos stole $96.
The officer followed the car into a parking lot and police surrounded the vehicle. The motorist then fled from the car on foot and Thanos began shooting at the police. Three officers returned fire at Thanos and a shootout erupted in the parking lot. Thanos then surrendered after he emptied his gun. No one was injured in the shootout but several vehicles were hit during the exchange of gunfire. On September 5, Delaware police turned over Thanos to Maryland State Police.
Execution Thanos was executed on May 17, 1994, by the state of Maryland via lethal injection, becoming the first person to be executed in Maryland since 1961, and the state's first post-Gregg execution. He was also the first person to be executed in Maryland via lethal injection. Thanos was 45 years old; his last words were "Adios!"
