Authorities say they uncovered a “dungeon” in Portway’s basement. CBS Boston reports the room was sound-proofed and contained handcuffs and a child-sized coffin. Disposable scalpels were also uncovered, the Associated Press reports.

“This man looks like he went beyond just having ideas,” Northeastern University criminologist Jack Levin told CBS Boston. “He made plans. He prepared by investing in a torture chamber. I think he would have done it.”

Portway may try to argue that the chats were part of a “fantasy life,” prosecutors said the memo, but they say “evidence clearly shows that is untrue.”
