John F. Baker

John F. Baker was a low-level criminal who frequently did small jobs, including those relating to sabotage.

History
John F. Baker was an unremarkable criminal involved in an extensive list of crimes, mostly small jobs. He eventually was hired on Christmas Eve by Enigma to sabotage an access panel at the Covetry Tower's network tower, rigging the device to detonate when someone tries to access it with a passkey. Enigma hired him to do this to ensure no one tried to access the network tower that Enigma had sabotaged earlier. This action resulted in the death of the Gotham Optics technician David Shannon. Batman, after uncovering the murder and deducing what happened, managed to evade Baker's rigged trap via his encryption device. Baker himself, however, would end up killed by Enigma in the Diamond District by the time Batman arrived at the tower, to eliminate anyone with knowledge on what happened, as Alfred revealed to Batman upon analyzing the fingerprints left on the device.
