True, but Corll did most of the killings and was well into his murder spree before Henley came into the picture. Corona is also another prolific serial killer that has pretty much been forgotten about, but his crimes weren't nearly has horrendous as Corll's. Hell, I'd rather end up in a Nazi death camp than on Corll's "torture board." And John Wayne Gacy was basically a copycat killer who was inspired by Corll's crimes. That's where he got the idea for his own "torture board." But even Gacy, as bad as he was, didn't do some of the terrible things that Corll did. I found this quote from Peter Sotos on the Usenet:

"The tender boy victims were shackled to a large, yellow, wooden plank
that had handcuffs attached to the corners... Dean would lick and suck on
the boys flacid from fright dicks and then violently rape their young
*******s. Most of the boys were between thirteen and sixteen. The youngest
was a delisious nine year old. Dean was especially severe and brutal in
the ass. Dean also used a seventeen-inch double ended ***** on the
youngsters little **** holes. The nine year old's ass must've split in
two! Electricians tape was fastened to the victims mouths to stop their
screaming. It should also be mentioned that Dean was of a very strong
constitution-six feet tall and 200 lbs with very little fat. Rest assured
that even without the monster ***** the little boys felt tremendous pain
as Dean pummelled and ripped into them with his hard and mighty cock. Most
of the boys were not homosexual but were straight young things from the
suburbs, making their *******s all the more pleasurable as Dean forced his
thick flesh up their blood and **** covered *******s. Dean also performed
ingenious and glorious tortures on the poor young babies. He would insert
long thin rods of glass into the little tykes ***** holes and then snap
the rod in two-leaving the end of the tube in the childs penis to torture
him unceasingly until he was finally allowed to die. The pain was
extreme-an intense pressure building up from inside the cock, blood
forcing itself out in slow, numbing drools, the constant reminder of the
pain fromthe brittle glass against the torn and bloody meat inside."
