and the Dallas police led the investigation into Mr. Rivello, and the police said he sent the strobe light knowing
that it was likely to lead Mr. Eichenwald, who has publicly discussed his epilepsy, into a seizure.
“But this is distinguishable because it is a targeted physical attack that was personal, using a plain-Jane tool.”
Investigators also searched one of Mr. Rivello’s digital accounts and found a screenshot of Mr. Eichenwald’s Wikipedia page
that had been altered to show a fake date of death of Dec. 16, 2016, the day after the strobe light attack, the Justice Department said.
“This electronic message was no different than a bomb sent in the mail or anthrax sent
in an envelope,” said Mr. Lieberman, who is working on the case as a pro bono service.
When Mr. Eichenwald clicked on the file, the strobe light triggered the seizure, his lawyer said.
