Bio: Kurt Bowman was a police officer at the Metropolis PD before
he was sentenced to death after it had turned out he killed a woman and
then covered up and pinned the blame for the murder on another man.
Bowman attempted to kill both Lois Lane and Clark Kent for getting too
close (had Clark Kent not been Superman, he would have succeeded in
finishing off Clark, multiple times), but eventually the truth came out.
In Bowmanís last breath, he figured out Supermanís secret identity, but
died in the gas chamber before he could tell anyone.
