Looking for a willing victim, Meiwes posted an advertisement at a website, The Cannibal Cafe, whose disclaimer mentions the distinction between reality and fantasy. Meiwes' post stated that he was "looking for a well-built 18 to 30-year-old to be slaughtered and then consumed".[7] Bernd Jürgen Brandes answered the advertisement. Many other people responded to the advertisement, but many backed out and none were forced to do anything they didn't want to do by Meiwes. Meiwes is openly bisexual,[8] as was Brandes.[9]
As is known from a videotape the two made when they met on March 9, 2001 in Meiwes' home in the small village of Rotenburg, Meiwes amputated Brandes' penis and the two men attempted to eat the penis together before Brandes was killed. Brandes had insisted that Meiwes attempt to bite his penis off. This did not work, though Meiwes was able to burst both of Brandes' testicles by biting them. Ultimately, Meiwes used a knife to remove Brandes' penis. Brandes apparently tried to eat some of his own penis raw, but could not because it was too tough and, as he put it, "chewy". Meiwes then sautéed the penis in a pan with salt, pepper, and garlic, but by then it was too burned to be consumed. He then chopped it up into chunks and fed it to his dog[3] According to journalists who saw the video (which has not been made public), Brandes may already have been too weakened from blood loss to actually eat any of his penis. Meiwes read a Star Trek book for three hours whilst his voluntary victim was bleeding to death in the bath. Meiwes apparently gave him large quantities of alcohol and pain killers, 30 sleeping pills and a bottle of schnapps, and finally killed him in a room that he had built in his house for this purpose, the Slaughter Room. After stabbing Brandes to death in the throat, he hung the body on a meathook and tore hunks of flesh from it; he even tried to grind the bones to use as flour. The whole scene was recorded on the two-hour video tape. Meiwes ate the body over the next 10 months, storing body parts in his freezer under pizza boxes and consuming up to 20 kg of the flesh.
