This week, See No Evil looks at the murder of Shirley Shell and the role surveillance footage played in bringing Michael Gary to justice for her murder.
On June 5, 2007, Michael Gary broke into the Shell family home in Edmond, Oklahoma. In the house, he found 67-year-old Shirley Shell and her mother-in-law; he held them both hostage while trying to obtain their credit card PINs.
Gary then murdered Shirley by stabbing her in the throat and fled the scene with $100 in spare change and the family’s credit cards.
Police initially struggled to come up with a suspect. Unfortunately, Shirley’s mother-in-law was blind, so she was unable to describe the killer. Neighbors had noticed a red car parked outside the home but were unable to identify the make or model.
However, when Gary began driving towards Ohio, he started making mistakes. He used one of the stolen credit cards along his route, which alerted investigators to his movements.
Investigators tracked Michael Gary across the country
Detectives began tracking him from Joplin, Missouri, up to Cleveland, Ohio.
A lengthy study of surveillance footage from a highway turnpike camera allowed detectives to finally identity Gary and his vehicle.
A search of Gary’s car revealed a key chain that belonged to the Shell family. Gary had absentmindedly grabbed the chain when he took a pile of loose change from their home. The police now had more than enough evidence to link him to Shirley Shell’s murder.
Gary had a lengthy criminal record, which included aggravated burglary, grand theft, sex offender violations, and other offenses. There was also a local open warrant for his arrest at the time of the murder.
Gary repeatedly claimed his innocence until after a suicide attempt when he finally decided to accept the weight of evidence against him and confessed to the crime.
He was sentenced to life in prison without parole. He was also convicted of burglary, possession of the stolen cards, and unauthorized usage of the cards.
Gary apologized to the Shell family; he said: “I’m sorry. I really am sorry.” The family thanked him for taking responsibility for what he had done.
