not the JLU cartoon. he used to be a regular on Superman TAS but was killed by darksied in one of the season finales (damn good episode too) besides that he's been a cop in the superman comics for some time now till the crisis
In S:TAS Turpin was drawn to resemble Kirby.
He was also around a lot in the Superman comics from the late 80's on. I think he disappeared from the pages around when Loeb took over (I wonder why...fuckin' Loeb
).
