During Stu's life as a GCPD detective, he became a corrupt cop involved in convicting innocent and frequently poor inmates with ADA Angus Stanton and Judge Raymond Calverick. He took the credit of his victims' arrest as a way to raise his reputation.
Targeted by the Executioner
In 2019, Stu was targeted by the Executioner who managed to kill him by setting up a trap inside a building at 200 Rucka Avenue, claiming he barricaded himself with some hostages and wanted to talk only to Stu. However, after he entered the building, it was a recorded voice and the officer was killed by a machine that could shoot bullets.
Sometime after Stu's death, his past crimes were subsequently exposed to the public by Kate Kane (under the persona of Batwoman). As a result, the District Attorney and Judge Davis Wellington re-opened all cases that were tainted by Stu and his co-conspirators' actions;
According to Luke Fox, Stu was an heroic individual and never stop until he brought the guilty to justice, however, this was ultimately nothing more than a façade.
In truth, Stu was a selfish, greedy, dishonourable and corrupt individual, as he and his co-conspirators, Angus Stanton and Raymond Calverick, framed several innocent individuals for crimes they did not commit, for his own personal gain in order to raise his reputation, and feeling no guilt, shame and remorse for his immoral actions; regardless whether or not these said individuals were wrongfully incarcerated or executed for crimes they did not commit; which eventually led to Stu's deserved death at the hands of Bertrand Eldon.
