Study Finds Texas Capital Punishment Had Deterrent Impact on Homicides

As many as 60 people may be alive today in Texas because two dozen convicted killers were executed last year in the nation's most active capital punishment state, according to a study of death penalty deterrence by researchers from Sam Houston State University and Duke University. A review of executions and homicides in Texas by criminologist Raymond Teske at Sam Houston in Huntsville and Duke sociologists Kenneth Land and Hui Zheng concludes a monthly decline of between 0.5 to 2.5 homicides in Texas follows each execution. “Evidence exists of modest, short-term reductions in the numbers of homicides in Texas in the month of or after executions,” the study published in a recent issue of Criminology, a journal of the American Society of Criminology, said. The study adds to decades of academic dissection of the death penalty and deterrence. Results over the years vary from capital punishment saving more lives than suggested in this study to no conclusive effect.
