The Milwaukee Journal Sentinel reported there were a half-dozen people who paid $30 each to take the tour Saturday, about a dozen others who showed up to protest the attempt to make "blood money" off the grisly Dahmer saga and another half-dozen reporters recording the event.
One customer, Paul Smith of Waukesha, said he decided to take the informational tour rather than spend his money in a bar, the newspaper said. Another, who gave his name only as John, said it was no different that going on a tour of Auschwitz Nazi death camp.
One of the protesters, Janie Hagen, whose brother Richard Guerrero was one of Dahmer's 17 victims, said it is just trying to cash in on a tragedy.
"If they are going to make a buck, it's blood money," she said.
Tour guide Nicholas Vollmann told his customers they were there to "learn from history."
"Unfortunately we can't bury our heads in the sand," he said. "This is the center of what would have been Jeffrey Dahmer's hunting ground.".
But, he added, he would not be delving into the cannibalism engaged in by Dahmer, the Journal Sentinel said.
Dahmer was killed by a fellow inmate in 1994 following his arrest and conviction.
