Stephen Anthony Mobley (July 13, 1965 – March 1, 2005) was a convicted murderer executed by the State of Georgia for the 1991 killing of John C. Collins, a 25-year-old college student working nights as a Domino's pizza store manager.
[3] According to relatives, Stephen Anthony Mobley had been a "difficult" child who had a history of lying, cheating, stealing, vandalizing, setting fires, and being cruel to animals.
[4] School records showed further evidence of lying, stealing, destruction of property, use of profanity to teachers, assaults on other students, and expulsions.
More serious offenses followed in Mobley's adolescence and by his mid twenties, he had served prison sentences for forgery and began a series of armed robberies.
[5] A number of social workers and psychologists had evaluated Mobley during his youth for possible learning disability or organic brain disorder, and despite finding him "manipulative, self-centered and impulsive," found no evidence of either.
[9] His attorneys argued that recent research that associated a mutation in the monoamine oxidase A (MAOA) gene with antisocial behavior in a Dutch family with a similar history should be allowed to be considered as mitigating evidence.
[6] Mobley's father apparently at this point replaced his son's attorneys, dropping the genetic arguments in favor of different lines of appeal.
[1] At 7:25 p.m., after the high court had denied the appeals, Mobley was prepared by prison officials by strapping him to a gurney and affixing a needle that would deliver the mixture of drugs designed to stop his heart.
