Nobody believed him. His family told him to get help. But Timothy Trespas, an out-of-work recording engineer in his early 40s, was sure he was being stalked, and not by just one person, but dozens of them.
He would see the operatives, he said, disguised as ordinary people, lurking around his Midtown Manhattan neighborhood. Sometimes they bumped into him and whispered nonsense into his ear, he said.
“Now you see how it works,” they would say.
At first, Mr. Trespas wondered if it was all in his head. Then he encountered a large community of like-minded people on the internet who call themselves “targeted individuals,” or T.I.s, who described going through precisely the same thing.
The group was organized around the conviction that its members are victims of a sprawling conspiracy to harass thousands of everyday Americans with mind-control weapons and armies of so-called gang stalkers. The goal, as one gang-stalking website put it, is “to destroy every aspect of a targeted individual’s life.”
